51 Questions — 2014
Q1 ⚖️ Polity & Constitution Amendment Procedure
Which Schedule of the Constitution of India contains provisions regarding disqualification of the members of Parliament and State Legislatures on the ground of defection?
  • A Second Schedule
  • B Fifth Schedule
  • C Eighth Schedule
  • D Tenth Schedule
✓ Correct answer: D — Tenth Schedule
The Tenth Schedule was added to the Constitution by the 52nd Constitutional Amendment Act, 1985 under Prime Minister Rajiv Gandhi. It provides for disqualification of members of Parliament and State Legislatures on the grounds of defection from their political party. A member is disqualified if they voluntarily give up their party membership or vote against the party's direction without prior permission. The only exception is a merger, which requires at least two-thirds of the members of the legislature party to agree. The Presiding Officer (Speaker/Chairman) decides defection cases, subject to judicial review. The Second Schedule lists emoluments of constitutional functionaries; the Fifth Schedule deals with Scheduled Areas and Scheduled Tribes; the Eighth Schedule lists official languages. UPSC 2014 confirmed the Tenth Schedule as the anti-defection provision schedule.
Q2 ⚖️ Polity & Constitution Parliament
Which one of the following is the largest Committee of the Parliament?
  • A The Committee on Public Accounts
  • B The Committee on Estimates
  • C The Committee on Public Undertakings
  • D The Committee on Petitions
✓ Correct answer: B — The Committee on Estimates
The Estimates Committee, with 30 members, is the LARGEST committee of the Parliament. All 30 members are drawn from the Lok Sabha — the Rajya Sabha has NO representation on this committee, which is unusual among financial committees. Its function is to examine the estimates included in the budget and suggest 'economies' in public expenditure, alternative policies, and improvements in organisation. By contrast, the Public Accounts Committee (PAC) has 22 members (15 from LS + 7 from RS), the Committee on Public Undertakings has 22 members (15 from LS + 7 from RS), and the Committee on Petitions has 15 members. The Estimates Committee was first constituted in 1950 on the recommendation of John Mathai, the then Finance Minister. It is sometimes called a 'continuous economy committee'. UPSC 2014 official answer: B.
Q3 ⚖️ Polity & Constitution Centre-State Relations
The sales tax you pay while purchasing a toothpaste is a:
  • A tax imposed by the Central Government
  • B tax imposed by the Central Government but collected by the State Government
  • C tax imposed by the State Government but collected by the Central Government
  • D tax imposed and collected by the State Government
✓ Correct answer: D — tax imposed and collected by the State Government
At the time UPSC asked this question (2014), Sales Tax / Value Added Tax (VAT) on intra-state sales of goods like toothpaste was both IMPOSED AND COLLECTED by the State Government under Entry 54 of the State List (List II) of the Seventh Schedule. Each state had its own VAT Act. Only inter-state sales (Central Sales Tax) were levied by the Centre but collected and retained by the originating State. Hence Option D was correct in 2014. NOTE FOR CURRENT CONTEXT: Since 1 July 2017, the Goods and Services Tax (GST) replaced most indirect taxes including state VAT and central excise. Under the GST regime, intra-state sales of toothpaste attract CGST (Central) + SGST (State) — collected by the respective governments and shared. Inter-state sales attract IGST (collected by Centre, then apportioned). So the modern answer would be different — but the historical 2014 answer remains D, reflecting the pre-GST taxation structure. UPSC 2014 official answer: D.
Q4 ⚖️ Polity & Constitution Constitutional Schedules
Which one of the following Schedules of the Constitution of India contains provisions regarding anti-defection?
  • A Second Schedule
  • B Fifth Schedule
  • C Eighth Schedule
  • D Tenth Schedule
✓ Correct answer: D — Tenth Schedule
The Tenth Schedule of the Constitution contains the anti-defection provisions, added by the 52nd Constitutional Amendment Act, 1985 during Rajiv Gandhi's prime ministership. It lays down the grounds for disqualification of legislators (MPs and MLAs) on grounds of defection: voluntarily giving up party membership, voting/abstaining contrary to party whip without prior permission, an independent member joining a political party after election, and a nominated member joining a party after six months. Originally it allowed split (1/3 of legislators) but the 91st Amendment 2003 removed this loophole and now only mergers (2/3 of legislators) are exempt. The Speaker/Chairman is the deciding authority, with the decision subject to judicial review (Kihoto Hollohan v. Zachillhu, 1992). The other options: Second Schedule deals with salaries/allowances of constitutional functionaries; Fifth Schedule with administration of Scheduled Areas and tribes; Eighth Schedule with the 22 recognised languages. UPSC 2014 official answer: D.
Q5 ⚖️ Polity & Constitution DPSP
In the Constitution of India, promotion of international peace and security is included in the:
  • A Preamble to the Constitution
  • B Directive Principles of State Policy
  • C Fundamental Duties
  • D Ninth Schedule
✓ Correct answer: B — Directive Principles of State Policy
The promotion of international peace and security is a Directive Principle of State Policy under Article 51 of the Constitution, which directs the State to: (a) promote international peace and security, (b) maintain just and honourable relations between nations, (c) foster respect for international law and treaty obligations in dealings of organised peoples with one another, and (d) encourage settlement of international disputes by arbitration. Article 51 reflects India's foreign policy ethos rooted in the freedom struggle and the Nehruvian commitment to non-alignment, peaceful coexistence (Panchsheel), and multilateralism. It is non-justiciable like all DPSPs but provides constitutional backing for India's positions at the UN and in international fora. The Preamble (Option A) declares broader objectives like sovereignty, socialism, secularism, justice, liberty, equality, fraternity — but does not specifically mention international peace. Fundamental Duties (Option C, Article 51A, added by 42nd Amendment 1976) lists ten/eleven duties for citizens but international peace is a DPSP, not a Fundamental Duty. Ninth Schedule (Option D) contains laws protected from judicial review under Article 31B. UPSC 2014 official answer: B.
Q6 ⚖️ Polity & Constitution Constitutional Foundations
A Constitutional Government is one which:
  • A places effective restrictions on individual liberty in the interest of State authority
  • B places effective restrictions on the authority of the State in the interest of individual liberty
  • C places effective restrictions on both individual liberty and State authority
  • D places no restriction on individual liberty and State authority
✓ Correct answer: B — places effective restrictions on the authority of the State in the interest of individual liberty
Constitutionalism, the foundational principle behind a constitutional government, is the doctrine that government power should be limited by the rule of law and that the authority of the State must be effectively restrained — most importantly to PROTECT individual liberty against arbitrary state action. A constitutional government distinguishes itself from despotism precisely by accepting limits on its own authority. These limits come through written constitutions (like India's), separation of powers, judicial review, fundamental rights enforceable in courts, federalism, and free elections. Famous formulation: 'Constitutional government is limited government.' Option B captures this exact concept. Option A is the opposite — that's authoritarianism. Option C is too broad and misses the point that liberty is the END and state restraint is the MEANS. Option D describes anarchy. India embodies constitutionalism through Part III (Fundamental Rights), Articles 32 and 226 (writ jurisdiction), the Basic Structure doctrine (Kesavananda Bharati 1973), and federal/judicial checks on government. UPSC 2014 official answer: B.
Q7 ⚖️ Polity & Constitution State Government
Which of the following are the discretionary powers given to the Governor of a State? 1. Sending a report to the President of India for imposing the President's rule 2. Appointing the Ministers 3. Reserving certain bills passed by the State Legislature for consideration of the President of India 4. Making the rules to conduct the business of the State Government Select the correct answer using the codes given below:
  • A 1 and 2 only
  • B 1 and 3 only
  • C 2, 3 and 4
  • D 1, 2, 3 and 4
✓ Correct answer: B — 1 and 3 only
The Governor's discretionary powers are exercised WITHOUT the aid and advice of the Council of Ministers, unlike the President's powers which are constitutionally bound by Cabinet advice (after the 42nd and 44th Amendments to Article 74). (1) Sending a report to the President recommending President's Rule under Article 356 — DISCRETIONARY. The Governor reports on whether the constitutional machinery in the State has broken down; this report can be made even against CM's advice. CORRECT. (2) Appointing Ministers — NOT discretionary. The Governor appoints Ministers on the advice of the Chief Minister under Article 164(1); the Governor's role is formal except in unusual situations. INCORRECT. (3) Reserving certain bills passed by the State Legislature for consideration of the President under Article 200 — DISCRETIONARY. The Governor 'shall reserve' bills that derogate from the High Court's powers, and 'may reserve' other bills if he/she considers them ultra vires, contrary to DPSPs, against national interest, etc. CORRECT. (4) Making rules for the conduct of State Government business — NOT discretionary. Article 166(3) requires the Governor to make rules 'for the more convenient transaction of the business of the Government of the State', but these are made on Cabinet's advice, not unilaterally. INCORRECT. Hence 1 and 3 — Option B. Other discretionary powers (not in this list) include: appointing CM when no party has majority, dismissing a CM who has lost majority, and special responsibilities under Articles 371-371J for certain states. UPSC 2014 official answer: B.
Q8 ⚖️ Polity & Constitution Union Executive
With reference to the Union Government, consider the following statements: 1. The Constitution of India provides that all Cabinet Ministers shall be compulsorily sworn as Privy Councillors before assuming office. 2. The Union Cabinet Secretariat operates under the direction of the Ministry of Parliamentary Affairs. Which of the statements given above is/are correct?
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: D — Neither 1 nor 2
Both statements are incorrect. (1) The Constitution of India does NOT provide for a Privy Council or for swearing in of Ministers as Privy Councillors. The 'Privy Council' was a colonial institution under the British Crown that ceased to be the appellate body for India in 1949 when the Supreme Court was established. India has no 'Privy Council' — Ministers are sworn in under the third schedule of the Constitution which prescribes oaths/affirmations of office and secrecy administered by the President under Article 75(4). The oath does not contain any reference to a Privy Council. INCORRECT. (2) The Cabinet Secretariat is a SEPARATE secretariat that functions DIRECTLY under the Prime Minister, NOT under the Ministry of Parliamentary Affairs. It is headed by the Cabinet Secretary, who is the senior-most civil servant of the Government of India and works as an aide to the PM. Its functions include providing secretarial assistance to the Cabinet and Cabinet Committees, coordinating administrative actions across ministries, and monitoring policy implementation. The Ministry of Parliamentary Affairs is a separate ministry that handles government business in Parliament — it does NOT direct the Cabinet Secretariat. INCORRECT. Hence Neither 1 nor 2 — Option D. UPSC 2014 official answer: D.
Q9 ⚖️ Polity & Constitution Parliament
With reference to the Parliament of India, consider the following statements: 1. A motion for adjournment of the proceedings of the House cannot be made unless 50 members support it. 2. To repeal an Act of Parliament, a fresh Bill has to be brought. Which of the statements given above is/are correct?
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: C — Both 1 and 2
Both statements are correct. (1) The Adjournment Motion is an extraordinary device used to draw the attention of the House to a definite matter of urgent public importance. Under the Rules of Procedure of Lok Sabha, the motion needs the support of at least 50 members to be admitted; only then can the Speaker permit it to be moved. Because it interrupts normal business and contains an element of censure against the government, the Rajya Sabha is not permitted this device. CORRECT. (2) An Act of Parliament can ONLY be repealed by another Act of Parliament — the standard legislative process. There are two ways: (a) a Repeal Bill, which is a fresh Bill specifically introduced to repeal one or more existing Acts (e.g., the Repealing and Amending Acts that periodically clean up the statute book); or (b) a substantive new Bill that contains a clause repealing the earlier Act. Either way, a fresh Bill MUST be brought to repeal an Act — the Constitution does not allow informal abrogation of statutes. CORRECT. Hence Both 1 and 2 — Option C. UPSC 2014 official answer: C.
Q10 💰 Indian Economy National Income
Increase in absolute and per capita real GNP do not connote a higher level of economic development, if
  • A Industrial output fails to keep pace with agricultural output
  • B Agricultural output fails to keep pace with industrial output
  • C Poverty and unemployment increase
  • D Imports grow faster than exports
✓ Correct answer: C — Poverty and unemployment increase
Economic development is a broader concept than mere GNP growth — it requires reduction in poverty, unemployment, and inequality alongside increases in national income. GNP growth can reflect income gains concentrated among a small elite while the majority remain poor and unemployed, meaning growth has not been inclusive. If poverty and unemployment increase simultaneously with rising GNP, the benefits of growth are not percolating to the population, and this does not constitute true development. Options A and B relate to structural composition of growth and are not directly linked to the development–growth distinction. Option D (imports exceeding exports) affects the trade balance but does not by itself negate development. UPSC tests the Amartya Sen/HDI-framework distinction: growth (quantitative) versus development (qualitative, multidimensional).
Q11 💰 Indian Economy Taxation
Which one of the following is not a feature of "Value Added Tax"?
  • A It is a multi-point destination-based system of taxation
  • B It is a tax levied on value added at each stage of production
  • C It avoids double taxation
  • D The tax burden ultimately falls on the consumer
✓ Correct answer: A — It is a multi-point destination-based system of taxation
Value Added Tax (VAT) as implemented in India before GST was an origin-based multi-point tax, not a destination-based one — the "destination-based" principle was a hallmark of GST (from 2017), not VAT. The description in Option A applies to GST, not VAT, making it the NOT-a-feature of VAT. VAT is indeed a multi-point tax levied on value added at each stage of production/distribution through the input tax credit mechanism (Option B correct feature). The input tax credit mechanism in VAT prevents tax cascading (double taxation), as tax is paid only on the value added at each stage (Option C correct feature). VAT is an indirect tax whose burden is ultimately borne by the final consumer through the price (Option D correct feature). India's state-level VAT (replaced by GST in 2017) was origin-based: revenue accrued to the producing/originating state rather than the consuming state — a major deficiency that GST's destination principle corrected.
Q12 💰 Indian Economy Five Year Plans & NITI Aayog
Which of the following is the theme of the Twelfth Five-Year Plan (2012–2017)?
  • A Inclusive Growth
  • B Faster, More Inclusive and Sustainable Growth
  • C Growth with Social Justice and Equity
  • D Faster and More Inclusive Growth
✓ Correct answer: B — Faster, More Inclusive and Sustainable Growth
The 12th Five-Year Plan (2012–2017) had the official theme "Faster, More Inclusive and Sustainable Growth" — the addition of "Sustainable" distinguishing it from the 11th Plan's theme. The 11th Five-Year Plan (2007-2012) had the theme "Faster and More Inclusive Growth" (Option D), which the 12th Plan built upon by adding the environmental sustainability dimension. The 10th Plan (2002-2007) focused on "Growth with Equity," and earlier plans emphasised different economic transformation objectives. The 12th Plan targeted an average GDP growth of 8% per annum, with sub-targets for poverty reduction, education, health, and sustainability. It was India's last Five-Year Plan — the Planning Commission was dissolved in January 2015, and from 2017-18, India moved to three-year Action Plans, seven-year strategies, and fifteen-year visions under NITI Aayog. The "Sustainable" addition in the 12th Plan reflected post-climate-change-awareness thinking integrated into development planning.
Q13 💰 Indian Economy Banking
Which of the following is the most likely consequence of implementing the "Inflation Targeting" framework in India?
  • A The exchange rates will become more stable.
  • B The currency will be appreciated permanently.
  • C GDP growth will not be significantly affected.
  • D India will become a developed economy in a shorter period.
✓ Correct answer: A — The exchange rates will become more stable.
Credible inflation targeting provides a stable and predictable nominal anchor — by committing to and maintaining low, stable CPI inflation, the central bank reduces macroeconomic uncertainty, anchors inflation expectations, and improves confidence in the domestic currency, all of which contribute to exchange rate stability (Option A correct). Research on countries that adopted inflation targeting frameworks shows improved exchange rate stability as a consistent outcome, since currency volatility is often driven by inflation uncertainty and unpredictable monetary policy. Option B (permanent currency appreciation) is incorrect — inflation targeting stabilises but does not permanently appreciate currency; exchange rates fluctuate with many other factors. Option C (no effect on GDP) is too dismissive — credible monetary policy has significant growth implications through lower risk premiums and improved credit environment. Option D (becoming developed economy faster) is an extreme overstatement of inflation targeting's scope. India formally adopted the flexible inflation targeting framework in May 2016 (4% CPI ±2%); the framework was extended to March 2031 in 2026.
Q14 💰 Indian Economy External Sector
With reference to Balance of Payments, which of the following constitutes/constitute the Current Account? (1) Balance of trade, (2) Foreign assets, (3) Balance of invisibles, (4) Special Drawing Rights. Select the correct answer using the codes given below.
  • A 1 only
  • B 2 and 3
  • C 1 and 3
  • D 1, 2 and 4
✓ Correct answer: C — 1 and 3
Option C (1 and 3) is CORRECT. The BALANCE OF PAYMENTS (BoP) is a systematic record of all economic transactions between residents of a country and the rest of the world during a specific period. It has TWO MAIN COMPONENTS: the CURRENT ACCOUNT and the CAPITAL ACCOUNT. THE CURRENT ACCOUNT records all transactions in goods, services, income, and transfers (i.e., transactions that are not asset transactions). It comprises: (1) BALANCE OF TRADE (Merchandise account) — CORRECT. The difference between the value of MERCHANDISE EXPORTS and IMPORTS. India typically runs a trade DEFICIT due to high oil and gold imports. (3) BALANCE OF INVISIBLES — CORRECT. The net of trade in SERVICES (software, tourism, transport, banking, insurance), INCOME (interest, dividends, profits), and TRANSFERS (workers' remittances, gifts, grants). India runs a SURPLUS on the invisibles account thanks to large IT/software exports and remittances from the Indian diaspora. The current account balance = Trade balance + Invisibles balance. Statement (2) FOREIGN ASSETS — INCORRECT. Foreign assets like FDI, FPI investments, loans, banking capital are part of the CAPITAL ACCOUNT, not the current account. The capital account records changes in asset ownership across borders. Statement (4) SPECIAL DRAWING RIGHTS (SDRs) — INCORRECT. SDRs are international reserve assets created by the IMF — they are part of the country's OFFICIAL RESERVES (under capital account / reserve account), NOT the current account. SDRs serve as a supplementary reserve asset and unit of account for IMF members. INDIA'S CAD: India's Current Account Deficit (CAD) is closely watched as it indicates external vulnerability. UPSC 2014 official answer: C.
Q15 💰 Indian Economy Indirect Taxation
What is/are the most likely advantages of implementing "Goods and Services Tax (GST)"? (1) It will replace multiple taxes collected by multiple authorities and will thus create a single market in India. (2) It will drastically reduce the "Current Account Deficit" of India and will enable it to increase its foreign exchange reserves. (3) It will enormously increase the growth and size of economy of India and will enable it to overtake China in the near future. Select the correct answer using the codes given below.
  • A 1 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: A — 1 only
Option A (1 only) is CORRECT. Statement 1 is CORRECT. The CORE RATIONALE for GST was indeed to REPLACE the cascading multiplicity of indirect taxes — Central Excise Duty, Service Tax, Additional Customs Duties, State VAT/Sales Tax, Luxury Tax, Octroi, Entry Tax, Entertainment Tax, Purchase Tax, etc. — with a SINGLE UNIFIED TAX collected at the destination on a value-added basis. By harmonising the tax structure across India, GST aims to create ONE COMMON NATIONAL MARKET, eliminating tax-rate disparities between states and removing inter-state checkposts that previously delayed goods movement. (Note: When this question was asked in 2014, GST was still being debated; it was finally implemented from 1 July 2017 via the 101st Constitutional Amendment Act 2016.) Statement 2 is INCORRECT. GST is a DOMESTIC INDIRECT TAX REFORM and does NOT directly impact the Current Account Deficit. CAD depends on trade balance (exports minus imports), services balance, and remittances — not on the structure of domestic indirect taxes. While GST may marginally improve export competitiveness over time, it cannot "drastically reduce" CAD. Statement 3 is INCORRECT and EXAGGERATED. While GST can boost growth by reducing inefficiencies and improving tax compliance, it cannot "ENORMOUSLY" increase growth such that India would "OVERTAKE CHINA in the near future." China's economy was approximately 5x India's size in 2014; bridging that gap is a generational endeavour requiring sustained reforms across many sectors. As of 2025, China's GDP is still ~4x India's. The statement is hyperbolic. So only statement 1 is correct. UPSC 2014 official answer: A.
Q16 💰 Indian Economy Banking
Supply of money remaining the same when there is an increase in demand for money, there will be:
  • A a fall in the level of prices
  • B an increase in the rate of interest
  • C a decrease in the rate of interest
  • D an increase in the level of income
✓ Correct answer: B — an increase in the rate of interest
Option B is CORRECT. According to KEYNESIAN MONETARY THEORY (LIQUIDITY PREFERENCE THEORY), the rate of INTEREST is determined by the interaction of the DEMAND for money and the SUPPLY of money in the money market. Equilibrium occurs where money supply (Ms) = money demand (Md). When the SUPPLY of money is FIXED (constant) and DEMAND FOR MONEY INCREASES — for example, due to higher transaction needs (rising income), greater precautionary balances, or higher speculative demand — there is excess demand for money relative to supply. WHAT HAPPENS NEXT: People want to hold more money than is available. To obtain more cash, they SELL BONDS and other financial assets. This SELLING PRESSURE on bonds DRIVES BOND PRICES DOWN, which mathematically means BOND YIELDS (interest rates) RISE. The interest rate continues rising until people are willing to hold the available stock of money — i.e., until equilibrium is restored. Conversely, an excess supply of money would cause people to buy bonds, pushing bond prices UP and interest rates DOWN. WHY OTHER OPTIONS ARE WRONG: (a) A fall in the price level — In the short run, increased demand for money (with constant supply) raises interest rates; price level adjustments take longer and are not the immediate result. (c) Decrease in interest rate — The OPPOSITE of what happens; this would occur with EXCESS supply, not excess demand. (d) Increase in income — Income causes higher money demand, not the other way around (this would be reverse causality). MACRO POLICY IMPLICATIONS: Central banks like the RBI use Open Market Operations to manage money supply and influence interest rates. UPSC 2014 official answer: B.
Q17 💰 Indian Economy Public Finance
Consider the following statements: (1) Tax revenue as a percent of GDP of India has steadily increased in the last decade. (2) Fiscal deficit as a percent of GDP of India has steadily increased in the last decade. Which of the statements given above is/are correct?
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: D — Neither 1 nor 2
Option D (Neither 1 nor 2) is CORRECT. This question was asked in UPSC 2014, so "the last decade" refers to approximately 2004-05 to 2013-14. Statement 1 is INCORRECT. India's TAX-GDP RATIO did NOT steadily increase in this period. It actually FLUCTUATED — reaching a peak of about 11.9% in 2007-08 (during the boom years), then DECLINING during the global financial crisis to around 9.7-10.0% in 2009-10 to 2011-12, before partially recovering. The tax-GDP ratio in 2013-14 was approximately 10.1% — LOWER than the pre-crisis peak. So it did not "steadily" rise. India's tax-GDP ratio has historically been low compared to developed economies (15-25%) and even comparable emerging markets. Statement 2 is INCORRECT. India's FISCAL DEFICIT as a percentage of GDP also did NOT steadily increase. Under FRBM (Fiscal Responsibility and Budget Management) Act 2003, the government targeted bringing fiscal deficit down. Fiscal deficit was around 4-4.5% in 2004-05, FELL to 2.5% in 2007-08 (the best year due to high tax buoyancy), then SHARPLY ROSE to 6.5% in 2009-10 due to stimulus during the global financial crisis, and was being brought down again to around 4.5% by 2013-14 under fiscal consolidation. So fiscal deficit FLUCTUATED — it did not steadily rise. Both statements describe smooth monotonic trends that did not actually occur. The correct answer is therefore "Neither 1 nor 2". POST-2014 UPDATE: India achieved a tax-GDP ratio of about 11-12% in recent years, while fiscal deficit briefly spiked to 9.2% in COVID year 2020-21 before being brought down to ~5% by 2024-25. UPSC 2014 official answer: D.
Q18 🌍 Geography Monsoon
Consider the following statements:
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: B — 2 only
Only Statement 2 is correct. Winds blowing between 30°S and 60°S in the Southern Hemisphere are indeed Westerlies — these are the Roaring Forties (40°S), Furious Fifties (50°S), and Shrieking Sixties (60°S), powerful westerly winds that encircle the globe in the Southern Ocean. Statement 1 is incorrect: Trade Winds blow from the subtropical high-pressure zones (around 30° latitude) toward the equatorial low, covering approximately 0°–30° latitudes in both hemispheres. The belt between 30°N and 60°N corresponds to Westerlies in the Northern Hemisphere (also called the Prevailing Westerlies or Anti-Trade Winds), not Trade Winds. This confusion between wind belts is a classic UPSC exam trap.
Q19 🌍 Geography Soils
Consider the following pairs:
  • A 1 only
  • B 1 and 3 only
  • C 3 only
  • D 1, 2 and 3
✓ Correct answer: C — 3 only
Only pair 3 is correctly matched. Thorn forests (scrub forests in arid and semi-arid zones receiving less than 70 cm annual rainfall) develop on sandy, loamy, and dry desert soils in Rajasthan, Gujarat, and the Deccan. Pair 1 is incorrect: Moist tropical evergreen forests (Western Ghats, Assam) typically occur on laterite and red soils, not specifically on Red and Yellow soils; Red and Yellow soils are characteristic of the semi-arid Deccan plateau and parts of Odisha where deciduous and scrub forests grow. Pair 2 is partly associative but not specifically correct: Black cotton soils are associated with both cotton cultivation and with dry/moist deciduous forests of the Deccan, but the one-to-one pairing of "dry deciduous forests" with "black cotton soils" is an oversimplification — deciduous forests also grow on red and laterite soils.
Q20 🌍 Geography World Geography
Mediterranean climate is found in all of the following regions except:
  • A Central Chile
  • B South-Western Australia
  • C South-Western parts of South Africa
  • D South-East coast of South America
✓ Correct answer: D — South-East coast of South America
Mediterranean climate occurs on the western coasts of continents between 30°–40° latitude (north or south), characterised by dry, hot summers and mild, wet winters. It is found in: the Mediterranean Basin (southern Europe, North Africa, western Asia), California and the Pacific coast of the USA, Central Chile (around Santiago, on South America's west coast), South-Western Australia (the Perth region), and the Cape region of South Africa (around Cape Town). The South-East coast of South America (southern Brazil, Uruguay, north-eastern Argentina) experiences a humid subtropical climate with year-round rainfall — not the summer drought characteristic of Mediterranean climate. This distinction between the western and eastern coasts of South America is a frequent UPSC exam point.
Q21 🌍 Geography World Geography
What is the correct sequence of occurrence of the following cities in South-East Asia as one proceeds from south to north? (Bangkok, Hanoi, Jakarta, Singapore)
  • A Jakarta — Singapore — Bangkok — Hanoi
  • B Bangkok — Singapore — Hanoi — Jakarta
  • C Jakarta — Bangkok — Singapore — Hanoi
  • D Bangkok — Hanoi — Jakarta — Singapore
✓ Correct answer: A — Jakarta — Singapore — Bangkok — Hanoi
The correct sequence from south to north is Jakarta → Singapore → Bangkok → Hanoi, based on their latitudes: Jakarta (Indonesia) lies at approximately 6°S — the southernmost and only city in the Southern Hemisphere. Singapore lies at approximately 1°N, just north of the equator. Bangkok (Thailand) lies at approximately 13°N. Hanoi (Vietnam) lies at approximately 21°N — the northernmost of the four. The question asks for a south-to-north arrangement, which follows this latitude order precisely. A common confusion arises when students use longitude instead of latitude; remembering that Indonesia is the only archipelago country straddling the Southern Hemisphere makes Jakarta the starting point. This question tests map-based locational knowledge of South-East Asian capitals, a frequently examined UPSC topic.
Q22 🌍 Geography Agriculture
Which one of the following states is the leading producer of tea in India?
  • A West Bengal
  • B Assam
  • C Kerala
  • D Karnataka
✓ Correct answer: B — Assam
Assam is India's leading producer of tea, contributing approximately 50–55% of India's total tea output. Tea in Assam is grown at low altitudes (unlike Darjeeling's hill gardens) in the Brahmaputra and Barak valley flood plains, producing the strong, malty, full-bodied CTC (Crush-Tear-Curl) tea popular for chai. Assam's tropical climate with high rainfall and humidity is ideal for tea. West Bengal (Darjeeling, Dooars, and Terai regions) is the second-largest producer and is famous for the premium Darjeeling "first flush" orthodox tea. Kerala and Tamil Nadu (Nilgiris) also produce significant quantities of tea, but both trail Assam and West Bengal. The Tea Board of India regulates tea production nationwide.
Q23 🌍 Geography Indian Geography
Which one of the following pairs of islands is separated from each other by the 'Ten Degree Channel'?
  • A Andaman and Nicobar
  • B Nicobar and Sumatra
  • C Maldives and Lakshadweep
  • D Sumatra and Java
✓ Correct answer: A — Andaman and Nicobar
The TEN DEGREE CHANNEL is a body of water in the Indian Ocean that SEPARATES the ANDAMAN ISLANDS to the north from the NICOBAR ISLANDS to the south. As the name suggests, it lies along the 10° NORTH latitude. The channel is approximately 150 km wide and ~1,000-1,300 m deep. It is an important shipping route connecting the Bay of Bengal to the Strait of Malacca and onward to Southeast Asia. STRATEGIC IMPORTANCE: The Andaman and Nicobar Islands are India's only Union Territory with a Tri-Service (Andaman and Nicobar Command established 2001) and a critical strategic outpost in the eastern Indian Ocean. Ships passing through the Ten Degree Channel are monitored, and the channel's narrowness gives India significant control over a key Indo-Pacific maritime route. Other related geographic facts: (a) The SIX DEGREE CHANNEL (along 6° N latitude) separates Great Nicobar Island (India) from Sumatra Island (Indonesia) — this is the southern boundary of Indian territorial waters in this region. (b) Nine Degree Channel separates Lakshadweep islands of Kavaratti from the southernmost Minicoy Island (along 9° N). (c) Eight Degree Channel separates Minicoy Island (Lakshadweep, India) from the Maldives (along 8° N) — important strategic chokepoint. (d) Sumatra and Java are separated by the SUNDA STRAIT (Indonesia). UPSC 2014 official answer: A.
Q24 🌍 Geography Climatology
The seasonal reversal of winds is the typical characteristic of:
  • A Equatorial climate
  • B Mediterranean climate
  • C Monsoon climate
  • D All of the above climates
✓ Correct answer: C — Monsoon climate
SEASONAL REVERSAL OF WINDS is the DEFINING characteristic of the MONSOON CLIMATE — in fact, the very word "monsoon" comes from the Arabic word "mausim" meaning "season," reflecting this pattern of wind reversal. THE MECHANISM: Monsoon climate occurs in regions where there is a dramatic seasonal shift in wind direction caused by differential heating of land and sea. (a) SUMMER MONSOON: During summer, continental landmasses heat up faster than oceans, creating LOW PRESSURE over land and HIGH PRESSURE over the cooler ocean. Winds blow from the ocean toward the land, bringing moisture-laden air that produces heavy rainfall. In India, the Southwest Monsoon (June-September) brings winds from the Arabian Sea and Bay of Bengal toward the Indian subcontinent, providing 80% of annual rainfall. (b) WINTER MONSOON: In winter, the pattern REVERSES. The continental landmass cools faster than the ocean, creating HIGH PRESSURE over land and lower pressure over the warmer ocean. Winds blow FROM land TOWARD ocean, generally dry and cool. In India, the Northeast Monsoon (October-December) brings winds from the Asian high-pressure zone southward, bringing rainfall to Tamil Nadu coast (which gets most of its rain in this season). REGIONS: Monsoon climates occur in South Asia (India, Bangladesh, Myanmar, Sri Lanka, parts of Pakistan), Southeast Asia (Vietnam, Thailand, Indonesia, Philippines), East Asia (China, Korea, Japan), parts of West Africa, and northern Australia. (a) EQUATORIAL CLIMATE — Has CONSISTENT high temperatures and rainfall year-round (no seasonal wind reversal) — characterized by tropical rainforests. (b) MEDITERRANEAN CLIMATE — Has hot dry summers and mild wet winters but the wind patterns don't fully reverse seasonally; characterized by dry westerlies in summer and cyclonic winter rains.

Q25 🌍 Geography Indian Geography
Consider the following rivers: 1. Barak 2. Lohit 3. Subansiri Which of the above flows/flow through Arunachal Pradesh?
  • A 1 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: B — 2 and 3 only
LOHIT and SUBANSIRI flow through Arunachal Pradesh; BARAK does not. (1) BARAK — INCORRECT. The Barak River originates in the Manipur hills (near Liyai in Senapati district), flows through the Cachar district of Assam, and enters Bangladesh where it splits into the Surma and Kushiyara rivers. It does NOT flow through Arunachal Pradesh. The Barak basin is the second-largest river system in northeast India after the Brahmaputra. (2) LOHIT — CORRECT. The Lohit River originates in the eastern Tibetan range and enters India in Anjaw district, eastern Arunachal Pradesh. It flows through Arunachal Pradesh's Lohit district before merging with the Brahmaputra (Siang) at Sadiya in Assam. The Lohit is one of the three principal sources/headwaters of the Brahmaputra in India (the others being the Siang and the Dibang). The Lohit Basin is geologically and ecologically significant, with several proposed hydro projects. (3) SUBANSIRI — CORRECT. The Subansiri (literally "river of gold" in Sanskrit/Assamese — for the gold dust historically panned from its waters) is the LARGEST tributary of the Brahmaputra. It originates in Tibet (~5,340 m altitude in the Himalayas) and enters India in West Siang district of Arunachal Pradesh. It flows through Arunachal Pradesh's Subansiri valley and into Assam, where it joins the Brahmaputra. The 2,000 MW Lower Subansiri Hydroelectric Project is being constructed on the Subansiri at the Arunachal-Assam border. It has been controversial due to seismic risks and impact on downstream communities. OTHER MAJOR ARUNACHAL RIVERS: Siang (the upper Brahmaputra entering India from Tibet via Arunachal), Dibang, Kameng, Tawang Chu, Kamla. Hence 2 and 3 only — Option B. UPSC 2014 official answer: B.
Q26 🌍 Geography World Geography
Turkey is located between:
  • A Black Sea and Caspian Sea
  • B Black Sea and Mediterranean Sea
  • C Gulf of Suez and Mediterranean Sea
  • D Gulf of Aqaba and Dead Sea
✓ Correct answer: B — Black Sea and Mediterranean Sea
Turkey is located in the geographically unique position between the BLACK SEA (to the north) and the MEDITERRANEAN SEA (to the south), connecting Europe and Asia. KEY GEOGRAPHIC FACTS: Turkey is a TRANSCONTINENTAL country — its small European portion (East Thrace, ~3% of land area) lies in southeastern Europe, while the larger Asian portion (Anatolia or Asia Minor, ~97%) lies in western Asia. The two parts are separated by the BOSPORUS strait, the Sea of MARMARA, and the DARDANELLES strait — collectively known as the Turkish Straits. NEIGHBOURING SEAS: (a) BLACK SEA to the NORTH — Turkey shares this with Russia, Ukraine, Romania, Bulgaria, Georgia. (b) MEDITERRANEAN SEA to the SOUTH — Turkey's southern coast faces the Eastern Mediterranean, with the island of Cyprus offshore. (c) AEGEAN SEA to the WEST — between Turkey and Greece, dotted with Greek and Turkish islands. (d) SEA OF MARMARA — an internal Turkish sea connecting the Black Sea (via Bosporus) to the Aegean (via Dardanelles), one of the world's smallest seas. STRATEGIC IMPORTANCE: The Bosporus is one of the world's busiest and most strategically important waterways — the only sea passage between the Black Sea and the rest of the world. Russia's Black Sea Fleet must pass through it to reach the Mediterranean. The Montreux Convention (1936) regulates passage. NEIGHBOURS: Turkey borders Greece, Bulgaria, Georgia, Armenia, Azerbaijan, Iran, Iraq, and Syria. (a) Black Sea + Caspian Sea — Wrong; the Caspian Sea is much further east and Turkey doesn't border it. (c) Gulf of Suez + Mediterranean — Wrong; this describes Sinai Peninsula (Egypt). (d) Gulf of Aqaba + Dead Sea — Wrong; this describes Israel/Jordan area. UPSC 2014 official answer: B.
Q27 🏛️ History & Culture Modern India
The Radcliffe Committee was appointed to:
  • A solve the problem of minorities in India
  • B give effect to the Independence Bill
  • C delimit the boundaries between India and Pakistan
  • D enquire into the riots in East Bengal
✓ Correct answer: C — delimit the boundaries between India and Pakistan
The Radcliffe Boundary Commission was constituted on 30 June 1947 under the chairmanship of British lawyer Sir Cyril Radcliffe to demarcate the boundaries between the soon-to-be independent dominions of India and Pakistan. Two Boundary Commissions — one for Punjab and one for Bengal — each had four members (two nominated by the Indian National Congress and two by the All India Muslim League), with Radcliffe presiding over both. He was given just five weeks to draw a line through provinces with mixed populations, an impossibly compressed timeline. The Radcliffe Award was published on 17 August 1947, two days AFTER independence, and triggered massive communal riots and one of the largest forced migrations in history. Option C is therefore correct. Option A (minority problem) was the broader concern of the Cabinet Mission Plan and Communal Award, not the Radcliffe Commission. Option B (Independence Bill) was given effect by the Indian Independence Act 1947, drafted in London. Option D (riots in East Bengal) refers to the Noakhali riots of 1946, which were investigated separately. UPSC 2014 official answer: C.
Q28 🏛️ History & Culture Ancient India
Which of the following Kingdoms were associated with the life of the Buddha? 1. Avanti 2. Gandhara 3. Kosala 4. Magadha Select the correct answer using the code given below:
  • A 1, 2 and 3
  • B 2 and 4
  • C 3 and 4 only
  • D 1, 3 and 4
✓ Correct answer: C — 3 and 4 only
Of the sixteen Mahajanapadas of the 6th century BCE, Buddha's life was directly associated with KOSALA and MAGADHA. (3) KOSALA: Buddha was born in Lumbini (in the Sakya republic, which was politically subordinate to Kosala), spent considerable time in Kosala's capital Sravasti, and resided at the Jetavana monastery there during many rainy seasons; King Prasenajit of Kosala was a close royal patron. (4) MAGADHA: Buddha attained enlightenment at Bodh Gaya in Magadha, frequented its capital Rajagriha, and was patronised by Kings Bimbisara and his son Ajatashatru. The First Buddhist Council was held at Rajagriha after his death. (1) AVANTI: A major Mahajanapada with capital Ujjayini in central India — Buddhism reached Avanti only later through the missionary Mahakatyayana, but Buddha himself never travelled there during his lifetime. (2) GANDHARA: In the far northwest (modern Peshawar/Taxila region) — far outside Buddha's travel range; Gandhara only became a Buddhist centre centuries later under the Mauryas and Kushanas. Hence only 3 and 4 — Option C. UPSC 2014 official answer: C.
Q29 🏛️ History & Culture Art & Culture
With reference to the cultural history of India, the term 'Panchayatan' refers to:
  • A an assembly of village elders
  • B a religious sect
  • C a style of temple construction
  • D an administrative functionary
✓ Correct answer: C — a style of temple construction
Panchayatan (Sanskrit: panch = five + ayatana = shrine/dwelling) is a Nagara-style temple architectural plan in which a main central shrine (housing the principal deity) is surrounded by four smaller subsidiary shrines at the four corners of the temple platform — together forming a quincunx of five shrines. The four corner shrines may house different deities of the principal god's family or related deities. Famous examples include the Dashavatara Temple at Deogarh (Gupta period, 6th century, Uttar Pradesh — one of the earliest), Lakshmana Temple at Khajuraho (Chandela), Brihadeshwara complex at Thanjavur (Chola), and Kandariya Mahadeva Temple at Khajuraho. The style emphasises hierarchy and cosmological symbolism — the central tower (shikhara) is taller than the four subsidiary ones. Option C is correct. UPSC 2014 official answer: C.
Q30 🏛️ History & Culture Modern India
The Partition of Bengal made by Lord Curzon in 1905 lasted until:
  • A the First World War when Indian troops were needed by the British and the partition was ended
  • B King George V abrogated Curzon's Act at the Royal Durbar in Delhi in 1911
  • C Gandhiji launched his Civil Disobedience Movement
  • D the Partition of India in 1947
✓ Correct answer: B — King George V abrogated Curzon's Act at the Royal Durbar in Delhi in 1911
The Partition of Bengal of 1905 (which divided Bengal into Bengal Presidency and Eastern Bengal & Assam, ostensibly for "administrative efficiency" but really to weaken the Bengali-speaking nationalist base by creating a Muslim majority province) provoked the massive Swadeshi Movement (1905–08) and Boycott Movement, with strong protests, picketing of British goods, and bonfires of foreign cloth. Tagore composed "Amar Sonar Bangla" (later Bangladesh's anthem) in protest. The British, finding the partition unworkable in the face of sustained agitation, formally annulled it at the Delhi Durbar of December 1911 — held to celebrate the coronation of King George V — when the King-Emperor announced the reunification of Bengal and the simultaneous shift of the imperial capital from Calcutta to Delhi. Option B is therefore correct. Option A (WWI) is wrong — the annulment came in 1911, three years before WWI began. Option C (Civil Disobedience, 1930) is much later. Option D (1947) is the second, communal partition of Bengal, an entirely different event. UPSC 2014 official answer: B.
Q31 🏛️ History & Culture Modern India
The 1929 Session of Indian National Congress is of significance in the history of the freedom movement because the:
  • A attainment of self-government was declared as the objective of the Congress
  • B attainment of Poorna Swaraj was adopted as the goal of the Congress
  • C Non-Cooperation Movement was launched
  • D decision to participate in the Round Table Conference in London was taken
✓ Correct answer: B — attainment of Poorna Swaraj was adopted as the goal of the Congress
The 1929 Lahore Session of the Indian National Congress, held on the banks of the Ravi under the presidency of Jawaharlal Nehru, formally adopted "Poorna Swaraj" (Complete Independence) as the goal of the Congress — a decisive break from the earlier dominion-status objective. The session passed the Poorna Swaraj resolution and called for celebration of 26 January 1930 as Independence Day, with the tricolour being unfurled at midnight on 31 December 1929. This date — 26 January — was later chosen as the date when the Constitution came into force in 1950, becoming Republic Day. The session also authorised the launch of the Civil Disobedience Movement, which began with Gandhi's Dandi Salt March in March 1930. Option B is correct. Option A (self-government/dominion status) was the older Calcutta resolution of 1928 (the Nehru Report). Option C (Non-Cooperation Movement, 1920) was launched at the Calcutta and Nagpur sessions. Option D (Round Table Conference, 1930–32) saw Congress boycott the first conference. UPSC 2014 official answer: B.
Q32 🏛️ History & Culture Modern India
The Ghadr (Ghadar) was a:
  • A revolutionary association of Indians with headquarters at San Francisco
  • B nationalist organization operating from Singapore
  • C militant organization with headquarters at Berlin
  • D communist movement for India's freedom with headquarters at Tashkent
✓ Correct answer: A — revolutionary association of Indians with headquarters at San Francisco
The Ghadar Party (Hindi/Urdu "Ghadar" = "revolt") was founded in 1913 in San Francisco, California, by Indian immigrants on the US West Coast — primarily Punjabi Sikh farmers and Indian students at Berkeley. The founders included Lala Hardayal (a former Stanford lecturer), Sohan Singh Bhakna (its first president), and Kartar Singh Sarabha. Headquartered at the Yugantar Ashram, San Francisco, the party published the weekly newspaper "Ghadar" in Urdu, Punjabi, Gujarati, and other Indian languages — circulated to Indian diaspora communities in North America, Asia, and Africa. Their goal was armed overthrow of British rule in India. With the outbreak of WWI in 1914, the Ghadar Party launched the abortive Ghadar Mutiny of 1915 — sending revolutionaries back to India to incite a military uprising, which was largely suppressed (the Lahore Conspiracy Case followed). Option A is correct. Option B (Singapore) refers loosely to later organisations like the Indian Independence League and INA under Subhas Chandra Bose. Option C (Berlin) refers to the Berlin Committee/Indian Independence Committee under Virendranath Chattopadhyaya during WWI — a separate revolutionary group. Option D (Tashkent) refers to the Communist Party of India founded by M.N. Roy in 1920. UPSC 2014 official answer: A.
Q33 🏛️ History & Culture Modern India
What were the objects of the Queen Victoria's Proclamation (1858)? 1. To disclaim any intention to annex Indian States 2. To place the Indian administration under the British Crown 3. To regulate East India Company's trade with India Select the correct answer using the code given below:
  • A 1 and 2 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: A — 1 and 2 only
Queen Victoria's Proclamation of 1 November 1858, read out in Allahabad by Lord Canning, formally announced the transfer of Indian administration from the East India Company to the British Crown after the Revolt of 1857 — giving effect to the Government of India Act 1858. (1) The Proclamation explicitly DISCLAIMED any further territorial expansion or annexation of Indian princely states — repudiating the Doctrine of Lapse used by Lord Dalhousie — and promised to respect the rights, dignity, and honour of native princes as their own. CORRECT. (2) The Proclamation transferred the territories, treaties, and powers of the Company to the Queen and placed Indian administration under the Crown, with the Secretary of State for India in London (replacing the Court of Directors) — the foundation of the Raj. CORRECT. (3) Statement 3 is INCORRECT — the Proclamation did not regulate the Company's trade with India because the Company's monopoly on Indian trade had ALREADY been abolished by the Charter Act of 1813 (and on China trade by the Charter Act of 1833); by 1858 the Company's commercial functions had ended decades earlier and only its administrative role survived, which the Proclamation now ended too. Hence 1 and 2 only — Option A. UPSC 2014 official answer: A.
Q34 🏛️ History & Culture Medieval India
Ibadat Khana at Fatehpur Sikri was:
  • A the mosque for the use of Royal Family
  • B Akbar's private prayer chamber
  • C the hall in which Akbar held discussions with scholars of various religions
  • D the room in which the nobles belonging to different religions gathered to discuss religious affairs
✓ Correct answer: C — the hall in which Akbar held discussions with scholars of various religions
The Ibadat Khana ("House of Worship") was a meeting hall built by Mughal Emperor Akbar at Fatehpur Sikri in 1575. Initially intended as a venue for theological discussions among Sunni Muslim ulama, Akbar progressively opened it to scholars of Shia Islam, Hindus, Jains, Zoroastrians (Parsis), Sikhs, and even Jesuit Christian missionaries from Goa (Aquaviva, Monserrate, and Henriques). The discussions held there from 1575 to 1582 reflected Akbar's growing interest in comparative religion and culminated in his proclamation of the Din-i-Ilahi (Divine Faith) in 1582 — a syncretic ethical code drawing from multiple religions, intended for his court elite. The Ibadat Khana itself was eventually closed when Akbar's religious experimentation provoked orthodox opposition, especially after the Mahzar of 1579. Abul Fazl's Ain-i-Akbari and Akbarnama record many of these debates. Option C is correct — it was a hall where AKBAR himself held discussions with scholars. Option D is wrong because it was Akbar (the emperor), not just the nobles, who presided over discussions. UPSC 2014 official answer: C.
Q35 🌿 Environment & Ecology Biodiversity
Which of the following criteria must a region satisfy to be declared a Biodiversity Hotspot by Conservation International?
  • A Must contain at least 1,500 endemic vascular plant species AND have lost at least 70% of its original habitat
  • B Must contain at least 5,000 endemic vertebrate species AND have less than 20% original vegetation remaining
  • C Must have a per-hectare species count above the global average AND receive international funding
  • D Must contain all major biome types AND be located in a tropical belt
✓ Correct answer: A — Must contain at least 1,500 endemic vascular plant species AND have lost at least 70% of its original habitat
Conservation International defines a Biodiversity Hotspot using two strict, non-negotiable criteria: (1) the region must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and (2) it must have lost at least 70% of its original primary native habitat. These thresholds were established by Norman Myers in his 1988 paper and refined by CI. Currently, 36 regions worldwide qualify as hotspots — they cover just 2.4% of Earth's land surface but support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species. India has four biodiversity hotspots wholly or partially within its territory: the Himalayas, Indo-Burma, Western Ghats & Sri Lanka, and Sundaland (which includes the Nicobar Islands). The criterion of "70% habitat lost" emphasises that hotspots are areas of both exceptional biodiversity and critical endangerment.
Q36 🌿 Environment & Ecology Ecology
A particular state in India has the following characteristics: (i) It is located on the same latitude which passes through northern Rajasthan. (ii) It has over 80% of its area under forest cover. (iii) Over 12% of India's forest cover is found in this state. Which one among the following states has all the above characteristics?
  • A Arunachal Pradesh
  • B Assam
  • C Himachal Pradesh
  • D Uttarakhand
✓ Correct answer: A — Arunachal Pradesh
Arunachal Pradesh satisfies all three conditions. It lies approximately between 27°N and 29°N latitude, which corresponds to the latitude band passing through northern Rajasthan. Approximately 79–80% of Arunachal Pradesh's area (about 83,743 sq km out of its total area of 83,743 sq km) is recorded as forest land — the highest forest cover percentage among larger Indian states. Arunachal Pradesh contributes approximately 11–12% of India's total forest and tree cover, making it one of the most forested states by absolute area as well. Its forests range from sub-tropical semi-evergreen forests in the foothills to temperate broadleaved, coniferous, and alpine meadows in the higher Himalayan zones, supporting exceptional biodiversity including the clouded leopard, Hoolock gibbon, and hundreds of orchid species.
Q37 🌿 Environment & Ecology Biodiversity
Consider the following statements about the IUCN Red List categories:
  • A 1 and 2 only
  • B 2 and 3 only
  • C 1 only
  • D 1, 2 and 3
✓ Correct answer: A — 1 and 2 only
Statements 1 and 2 are correct. The IUCN Red List uses nine categories: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD), and Not Evaluated (NE). Critically Endangered represents the highest extinction risk for species still surviving in the wild — species categorised CR face an extremely high risk of extinction (meeting specific quantitative criteria around population decline, small size, or small range). "Extinct in the Wild" (EW) applies to species that survive only in captivity, in cultivation, or as a naturalised population outside the historical range — examples include Père David's Deer and the Scimitar-horned Oryx. Statement 3 is incorrect: "Data Deficient" (DD) means there is inadequate information to assess the species' conservation status — it explicitly does NOT indicate the species is non-threatened; a DD species could in fact be highly threatened, but lack of data prevents formal categorisation.
Q38 🔬 Science & Technology Energy Technology
With reference to technologies for solar power production, consider the following statements: 1. "Photovoltaics" is a technology that generates electricity by direct conversion of light into electricity, while "Solar Thermal" is a technology that utilises the Sun's rays to generate heat which is further used in electricity generation process. 2. Photovoltaics generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC). 3. India has manufacturing base for Solar Thermal technology, but not for Photovoltaics. Which of the statements given above is/are correct?
  • A 1 only
  • B 2 and 3 only
  • C 1, 2 and 3
  • D None
✓ Correct answer: A — 1 only
Only statement 1 is correct. (1) PV vs SOLAR THERMAL — CORRECT. The two technologies use fundamentally different physical principles: PHOTOVOLTAIC (PV) cells use the photoelectric effect to directly convert sunlight into electricity through semiconductors (typically silicon). When photons strike the PV cell, they free electrons in the semiconductor, generating a flow of electric current. SOLAR THERMAL (also called concentrating solar power, CSP) uses mirrors or lenses to concentrate sunlight onto a receiver, where the heat is used to boil water or heat a fluid (e.g., molten salt) to drive a conventional steam turbine and generate electricity. Examples: parabolic trough, power tower, dish-Stirling, linear Fresnel reflector. (2) AC vs DC — INCORRECT. The opposite is true. PHOTOVOLTAICS generates DIRECT CURRENT (DC) — solar cells produce DC electricity, which must be converted to AC using inverters for grid use. SOLAR THERMAL plants use steam turbines coupled to ALTERNATORS, which generate ALTERNATING CURRENT (AC) directly — same as conventional thermal/coal/gas/nuclear power plants. The statement reverses these. (3) MANUFACTURING BASE — INCORRECT. India has a SUBSTANTIAL manufacturing base for PHOTOVOLTAICS — including silicon ingot, wafer, cell, and module production by companies like Adani Solar, Vikram Solar, Tata Power Solar, Waaree, etc., supported by the PLI (Production Linked Incentive) scheme since 2021. India's PV manufacturing capacity is targeted to reach 100 GW by 2030. Solar Thermal/CSP, by contrast, has very LIMITED manufacturing in India and is much less commercially deployed (only a few demonstration plants like Reliance's 125 MW Dhursar in Rajasthan). The statement reverses the actual situation. Hence only statement 1 — Option A. UPSC 2014 official answer: A.
Q39 🔬 Science & Technology Defence Technology
With reference to Agni-IV Missile, which of the following statements is/are correct? 1. It is a surface-to-surface missile. 2. It is fuelled by liquid propellant only. 3. It can deliver one-tonne nuclear warhead about 7500 km away. Select the correct answer using the codes given below:
  • A 1 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: A — 1 only
Only statement 1 is correct. AGNI-IV is an intermediate-range ballistic missile (IRBM) developed by India's DRDO under the Integrated Guided Missile Development Programme (IGMDP), first successfully tested on 15 November 2011. (1) SURFACE-TO-SURFACE — CORRECT. Agni series missiles are all SURFACE-TO-SURFACE BALLISTIC MISSILES designed to deliver conventional or nuclear warheads against ground targets at long ranges. They are launched from mobile or fixed surface launchers and follow ballistic trajectories. (2) LIQUID PROPELLANT ONLY — INCORRECT. Agni-IV is a TWO-STAGE SOLID-PROPELLANT missile (both stages use composite solid propellant). Solid fuel is preferred for military missiles because it allows quick launch, requires less infrastructure, can be stored ready-to-launch for years, and is less hazardous than liquid propellants. The earlier Agni-I and Agni-II had a SOLID first stage with a LIQUID second stage in some variants, but Agni-IV is fully solid. (3) 7,500 KM RANGE — INCORRECT. Agni-IV has a range of approximately 4,000 km — bringing all of Pakistan and significant parts of China within reach, but NOT 7,500 km. The 5,000+ km range belongs to AGNI-V (intercontinental class, first tested 2012). India's 7,000+ km class would be Agni-VI (under development). The statement is therefore wrong on the range. KEY AGNI MISSILE RANGES: Agni-I ~700 km; Agni-II ~2,000-3,500 km; Agni-III ~3,000-5,000 km; Agni-IV ~4,000 km; Agni-V ~5,000-8,000 km; Agni-P (Prime) ~1,000-2,000 km. Hence only statement 1 — Option A. UPSC 2014 official answer: A.
Q40 🔬 Science & Technology Biotechnology
In addition to fingerprint scanning, which of the following can be used in the biometric identification of a person? 1. Iris scanning 2. Retinal scanning 3. Voice recognition Select the correct answer using the codes given below:
  • A 1 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: D — 1, 2 and 3
All three are valid biometric identification methods, alongside fingerprints. BIOMETRIC IDENTIFICATION uses unique physiological or behavioural characteristics to verify individual identity. (1) IRIS SCANNING — CORRECT. The iris (the coloured ring around the pupil) has a unique pattern of furrows, ridges, freckles, and crypts formed during fetal development. Iris patterns are highly stable, complex, and unique even in identical twins. India's AADHAAR system uses iris scanning for biometric enrolment alongside fingerprints and photograph. Iris recognition is considered one of the most accurate biometric methods. (2) RETINAL SCANNING — CORRECT. The retina (the light-sensitive layer at the back of the eye) has a unique pattern of blood vessels (retinal vasculature) that does not change throughout adult life. Retinal scanning is highly accurate but requires close eye contact with a scanning device, making it less user-friendly than iris scanning. Used in high-security facilities. NOTE: Iris ≠ Retina. The iris is the visible coloured part; the retina is the inner light-sensing layer. (3) VOICE RECOGNITION (also called speaker recognition) — CORRECT. Each person's voice has a unique acoustic profile based on the physiology of the vocal tract, mouth, sinuses, and learned speech patterns. Modern voice biometric systems use spectral analysis, pitch, formants, and AI algorithms to identify speakers with high accuracy. Used in phone banking, call centres, and smart speakers. OTHER BIOMETRIC METHODS not in this question: facial recognition, hand geometry, palm print, DNA profiling, gait recognition, vein pattern recognition, ear shape, signature dynamics, keystroke dynamics. UIDAI's Aadhaar uses fingerprints (10 fingers) + iris (2 eyes) + facial photograph as the standard biometric set. Hence all three — Option D. UPSC 2014 official answer: D.
Q41 🔬 Science & Technology Space Technology
Which of the following pair(s) is/are correctly matched? Spacecraft : Purpose 1. Cassini-Huygens : Orbiting the Venus and transmitting data to the Earth 2. Messenger : Mapping and investigating the Mercury 3. Voyager 1 and 2 : Exploring the outer solar system Select the correct answer using the codes given below:
  • A 1 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: B — 2 and 3 only
Pairs 2 and 3 are correctly matched; pair 1 is INCORRECTLY matched. (1) CASSINI-HUYGENS : VENUS — INCORRECT. Cassini-Huygens was a joint NASA-ESA-ASI mission launched in 1997 to study SATURN and its moons — NOT Venus. The Cassini orbiter studied Saturn, its rings, and its moons (especially Titan and Enceladus) from 2004 to 2017, when it was deliberately crashed into Saturn's atmosphere ("Grand Finale") to avoid contaminating moons that might harbour life. The Huygens lander descended to TITAN (Saturn's largest moon) in January 2005 — the first landing on a body in the outer solar system. Cassini discovered Saturn's liquid water plumes on Enceladus and methane lakes on Titan. (2) MESSENGER : MERCURY — CORRECT. MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) was a NASA mission launched in 2004 to orbit and study MERCURY — the closest planet to the Sun. It entered orbit around Mercury in March 2011 (the first spacecraft ever to do so) and operated until April 2015, providing detailed maps of Mercury's surface, magnetic field, and exosphere. (3) VOYAGER 1 AND 2 : OUTER SOLAR SYSTEM — CORRECT. NASA's Voyager 1 and Voyager 2 spacecraft were launched in 1977 to explore the outer solar system. Voyager 2 visited all four giant planets — JUPITER (1979), SATURN (1981), URANUS (1986), and NEPTUNE (1989) — the only spacecraft to have visited Uranus and Neptune. Voyager 1 visited Jupiter and Saturn, then headed out of the solar system. In August 2012, Voyager 1 became the first human-made object to enter INTERSTELLAR SPACE (crossing the heliopause). Voyager 2 followed in November 2018. Both carry the famous Golden Records with sounds and images of Earth. Both are still operational as of 2026, though their power and instruments are gradually failing. Hence 2 and 3 only — Option B. UPSC 2014 official answer: B.
Q42 🤝 International Relations International Organisations
With reference to a grouping of countries known as BRICS, consider the following statements:
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: B — 2 only
Only Statement 2 is correct. South Africa joined BRIC in 2010, making it BRICS, and it was the last member to join. Statement 1 is incorrect: the first BRIC summit was held in Yekaterinburg, Russia in June 2009 (not Rio de Janeiro). Rio de Janeiro hosted the 4th BRICS Summit in 2012.
Q43 🤝 International Relations Multilateral Groupings
With reference to a grouping of countries known as BRICS, consider the following statements: (1) The First Summit of BRICS was held in Rio de Janeiro in 2009. (2) South Africa was the last to join the BRICS grouping. Which of the statements given above is/are correct?
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: B — 2 only
Option B (2 only) is CORRECT. Statement 1 is INCORRECT. The first BRIC Summit (the grouping was called BRIC then, with no "S") was held in YEKATERINBURG, RUSSIA on 16 June 2009 — NOT in Rio de Janeiro. Russia hosted the inaugural summit, and the BRIC formation was originally proposed by economist Jim O'Neill of Goldman Sachs in 2001. Subsequent summits: Brasília (2010, where SOUTH AFRICA was invited), Sanya (2011, first summit attended by South Africa), New Delhi (2012), Durban (2013), Fortaleza (2014, where the New Development Bank was launched). Statement 2 is CORRECT. SOUTH AFRICA was the LAST original founding member to join the grouping, transforming BRIC into BRICS in 2010. South Africa was formally invited at the 2010 Brasília summit and attended its first summit as a member at the 2011 Sanya summit in China. South Africa's addition gave the grouping an African voice and full continental representation. RECENT EXPANSION (post-2014, beyond the question scope but for context): At the 2023 Johannesburg summit, BRICS was expanded to include 6 new members: Argentina (later withdrew), Egypt, Ethiopia, Iran, Saudi Arabia, and the UAE. By 2024, the grouping is sometimes called BRICS+. KEY INSTITUTIONS: New Development Bank (NDB) headquartered in Shanghai, founded 2014; Contingent Reserve Arrangement (CRA) — financial safety net. UPSC 2014 official answer: B.
Q44 🤝 International Relations International Organizations
Consider the following countries: (1) Denmark, (2) Japan, (3) Russian Federation, (4) United Kingdom, (5) United States of America. Which of the above are the members of the "Arctic Council"?
  • A 1, 2 and 3
  • B 2, 3 and 4
  • C 1, 4 and 5
  • D 1, 3 and 5
✓ Correct answer: D — 1, 3 and 5
Option D (Denmark, Russian Federation, USA) is CORRECT. The ARCTIC COUNCIL is a high-level intergovernmental forum established by the Ottawa Declaration of 1996, addressing issues faced by the Arctic governments and indigenous peoples of the Arctic. It has EIGHT FULL MEMBER STATES — all of which have territory above the Arctic Circle: (1) CANADA, (2) DENMARK (including Greenland and the Faroe Islands), (3) FINLAND, (4) ICELAND, (5) NORWAY, (6) RUSSIAN FEDERATION, (7) SWEDEN, and (8) UNITED STATES (Alaska). From the question's list: Denmark (1) — YES; Japan (2) — NO (only an Observer); Russian Federation (3) — YES; UK (4) — NO (only an Observer); USA (5) — YES. So the answer is 1, 3 and 5 — Option D. INDIGENOUS PARTICIPATION: The Council includes SIX organisations representing Arctic indigenous peoples as PERMANENT PARTICIPANTS — Aleut International Association, Arctic Athabaskan Council, Gwich'in Council International, Inuit Circumpolar Council, RAIPON (Russia), and Saami Council. OBSERVERS: Currently 13 non-Arctic state observers including INDIA (admitted in 2013), CHINA, JAPAN, SOUTH KOREA, SINGAPORE, UK, France, Germany, Italy, Netherlands, Poland, Spain, Switzerland — plus various intergovernmental and NGO observers. India's observer status reflects its growing interest in Arctic research (Himadri research station in Svalbard since 2008). PURPOSE: Cooperation on environment protection, sustainable development, climate change, and indigenous well-being. The Council does NOT deal with military security. UPSC 2014 official answer: D.
Q45 🤝 International Relations Geopolitics
"The Arab Spring" originally started in:
  • A Egypt
  • B Lebanon
  • C Syria
  • D Tunisia
✓ Correct answer: D — Tunisia
Option D (TUNISIA) is CORRECT. The ARAB SPRING was a revolutionary wave of protests, uprisings, and armed conflicts that swept across the Arab world starting in late 2010. It originated in TUNISIA. THE TRIGGER: On 17 December 2010, MOHAMED BOUAZIZI, a 26-year-old Tunisian street vendor in the small town of Sidi Bouzid, set himself ON FIRE in front of the local government building in protest against police harassment, the confiscation of his fruit cart, and humiliation by a policewoman. His desperate act of self-immolation became the catalyst that ignited mass protests across Tunisia against unemployment, inflation, corruption, lack of political freedom, and the authoritarian regime of President Zine El Abidine Ben Ali. Within weeks, protests spread nationwide. On 14 JANUARY 2011, after just 28 days of mass protests (the JASMINE REVOLUTION), Ben Ali fled to Saudi Arabia, ending his 23-year rule. SPREAD ACROSS THE REGION: The Tunisian success inspired similar uprisings across the Arab world: EGYPT (Tahrir Square protests, January 2011) — Hosni Mubarak resigned February 2011 after 30 years; LIBYA — civil war and NATO intervention, Gaddafi killed October 2011; YEMEN — Saleh resigned 2012; SYRIA — protests escalated into a brutal civil war that continues; BAHRAIN — protests crushed by Saudi-led intervention; smaller protests in Algeria, Iraq, Jordan, Kuwait, Morocco, Oman, Sudan. AFTERMATH: Tunisia was the only country to undergo a relatively successful democratic transition (Nobel Peace Prize to the Tunisian National Dialogue Quartet in 2015). Most other Arab Spring countries either reverted to authoritarianism, descended into civil war, or experienced state collapse. UPSC 2014 official answer: D.
Q46 🤝 International Relations International Conventions
With reference to a conservation organization called "Wetlands International", which of the following statements is/are correct? (1) It is an intergovernmental organization formed by the countries which are signatories to the Ramsar Convention. (2) It works at the field level to develop and mobilize knowledge, and use the practical experience to advocate for better policies. Select the correct answer using the codes given below.
  • A 1 only
  • B 2 only
  • C Both 1 and 2
  • D Neither 1 nor 2
✓ Correct answer: B — 2 only
Option B (2 only) is CORRECT. Statement 1 is INCORRECT. WETLANDS INTERNATIONAL is a global NON-PROFIT, NON-GOVERNMENTAL ORGANISATION (NGO) — NOT an intergovernmental organisation formed by Ramsar signatories. It was established in 1995 through the merger of three regional wetland conservation organisations (the International Waterfowl & Wetlands Research Bureau IWRB based in UK, Asian Wetland Bureau AWB, and Wetlands for the Americas WA). Its global headquarters is in Ede (Netherlands), with offices and partners in over 100 countries. Statement 2 is CORRECT. Wetlands International is a CIVIL SOCIETY ORGANISATION that works directly with governments, scientists, local communities, donors, and the private sector. It conducts FIELD-LEVEL conservation work, scientific research, biodiversity monitoring (e.g., the International Waterbird Census), capacity building, and ADVOCACY for stronger wetland protection policies. It acts as a knowledge bridge — using practical field experience to inform global policy frameworks. RAMSAR LINK: Wetlands International is one of the FIVE OFFICIAL INTERNATIONAL ORGANISATION PARTNERS (IOPs) of the RAMSAR Convention on Wetlands (alongside BirdLife International, IUCN, WWF, and IWMI). It provides scientific and technical advice to the Ramsar Secretariat and helps implement conservation initiatives in Ramsar sites worldwide. The Ramsar Convention itself (signed 1971 in Ramsar, Iran) IS an intergovernmental treaty — but Wetlands International is a separate civil society partner, not the treaty body. INDIA: India has 89+ Ramsar sites (as of 2024); Wetlands International South Asia operates from New Delhi. UPSC 2014 official answer: B.
Q47 👥 Society Society & Social Issues
With reference to 'Changpa' community of India, consider the following statements:
  • A 1 only
  • B 2 and 3 only
  • C 3 only
  • D 1, 2 and 3
✓ Correct answer: B — 2 and 3 only
Only statements 2 and 3 are correct. The Changpa are a semi-nomadic Tibetan people concentrated in the Changtang plateau of Ladakh and parts of Jammu and Kashmir — not Uttarakhand, making statement 1 incorrect. They rear the Changthangi (Changtang) goats, also called Pashmina goats, whose undercoat yields the prized Pashmina fibre used in fine shawls. The Changpa have been classified as Scheduled Tribes in India.
Q48 ⚗️ General Science Biology
With reference to vitamins, consider the following statements:
  • A 1 and 2 only
  • B 2 and 3 only
  • C 1 and 3 only
  • D 1, 2 and 3
✓ Correct answer: D — 1, 2 and 3
All three statements are correct. Vitamin A (retinol) is a fat-soluble vitamin stored primarily in the liver — specifically in hepatic stellate cells as retinyl esters; this storage allows the body to draw on reserves during periods of dietary deficiency. Vitamin B12 (cobalamin) is produced by micro-organisms (bacteria) in the human gut, particularly in the colon; however, dietary intake is still necessary because the absorption site (terminal ileum) is upstream of where gut bacteria synthesise it, so colonic B12 cannot be directly absorbed. Vitamin D3 (cholecalciferol) is synthesised in the skin through photochemical conversion of 7-dehydrocholesterol upon exposure to ultraviolet B (UVB) radiation from sunlight, earning it the nickname "sunshine vitamin." Vitamin D then undergoes hydroxylation in the liver and kidneys to become its active form (calcitriol), which regulates calcium absorption. UPSC tests the unique metabolic origin and storage of each vitamin to distinguish fat-soluble from water-soluble types.
Q49 ⚗️ General Science Physics
Which of the following is/are the characteristic/characteristics of electromagnetic waves?
  • A They require a medium for propagation.
  • B They travel through vacuum at the speed of light.
  • C They are longitudinal waves.
  • D Both (a) and (c)
✓ Correct answer: B — They travel through vacuum at the speed of light.
Electromagnetic (EM) waves — which include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays — are transverse waves consisting of oscillating electric and magnetic fields perpendicular to each other and to the direction of propagation. The defining characteristic of EM waves is that they do NOT require a material medium for propagation and can travel through vacuum (outer space) at the speed of light: approximately 3 × 10⁸ m/s (299,792,458 m/s precisely). Option A is incorrect — that describes mechanical waves (sound, water waves, seismic waves) which require a medium; EM waves can travel through vacuum, which is how sunlight and starlight reach Earth. Option C is incorrect — EM waves are transverse waves (oscillations perpendicular to direction of travel), not longitudinal waves (oscillations parallel to direction of travel, like sound). The electromagnetic spectrum was unified theoretically by James Clerk Maxwell in 1865 when he showed that light is an electromagnetic wave. UPSC tests this to distinguish wave types and their fundamental properties.
Q50 ⚗️ General Science Chemistry
Which one of the following is used as a mordant in dyeing fabrics?
  • A Potassium dichromate
  • B Potassium permanganate
  • C Potassium nitrate
  • D Potassium chloride
✓ Correct answer: A — Potassium dichromate
Potassium dichromate (K₂Cr₂O₇) is used as a mordant in the textile dyeing industry, particularly for chrome dyeing of wool; mordants are metallic compounds that form coordinate bonds or ionic complexes with both the dye molecules and the textile fibres (wool thiol groups reduce hexavalent chromium to trivalent Cr³⁺, which then forms stable coordination complexes with the dye and fibre), fixing the colour permanently and improving fastness to washing and light. The chrome-mordant process has been used since at least 1820 and produces exceptionally lightfast yellows, browns, and navy colours on wool. Potassium permanganate (KMnO₄) is a powerful oxidising agent used as a disinfectant, bleaching agent, and in water treatment — not as a mordant. Potassium nitrate (KNO₃) is used in fertilisers, gunpowder, and food preservation. Potassium chloride (KCl) is used as a fertiliser (muriate of potash) and in medicine as a potassium supplement. Other common mordants include alum (potassium aluminium sulphate), ferrous sulphate (iron mordant producing dark colours), and copper sulphate (producing blue-green shades). UPSC tests industrial chemistry applications including mordants as part of the chemistry of everyday life.
Q51 ⚗️ General Science Space Technology
India's first dedicated multi-wavelength space observatory is
  • A INSAT-3D
  • B Astrosat
  • C Chandrayaan-1
  • D Resourcesat-2
✓ Correct answer: B — Astrosat
AstroSat, launched by ISRO on 28 September 2015 using PSLV-C30 into a 650 km orbit, is India's first dedicated multi-wavelength space observatory — designed to observe the universe simultaneously in visible light, ultraviolet (UV), and X-ray wavelengths using its five scientific payloads (UVIT, LAXPC, SXT, CZTI, and SSM). AstroSat has made significant contributions to astronomy including detecting the farthest ultraviolet light ever seen from a galaxy (in 2020), studying X-ray binaries, neutron stars, black holes, and supernova remnants. The question's year is listed as 2014 but AstroSat was actually announced and in development long before its 2015 launch; INSAT-3D is a meteorological satellite for weather observation — not a multi-wavelength observatory. Chandrayaan-1 was India's first lunar probe (2008), not an astronomical observatory; Resourcesat-2 is a remote sensing satellite for land and ocean applications. AstroSat completed 10 years of successful operation in September 2025 and continues to function. UPSC asks this to test knowledge of India's major space science missions beyond launch vehicles.
