UPSC 2012 CSAT PYQs with Answers

He was congratulated as a hero because the bundle he carried turned out to be a baby, so he saved a life even if unintentionally.

The passage says he lost his way in the smoke-filled passage and missed the stairway. The immediate reason for entering another room was the smoke-filled passage.

Inside the tent it was not too cold for them to take off their gloves. Therefore they took off their gloves because it was not very cold.

The passage directly says everything took five times as long because there was not enough air to breathe. The delay is due to thin air at high altitude.

"Highest camp" means a camp pitched at a height higher than any camp made before. It does not necessarily mean they had reached the summit.

The narrator adapts to jail surroundings by becoming familiar with them and treating even small features as companions. This suggests one can adjust to uncongenial surroundings.

The passage focuses on the prisoner noticing marks, dents, tufts of grass, stones, insects and lizards in minute detail. It is chiefly about his close observation of surroundings.

The sentence means the narrator had become deeply familiar with every detail of the cell after long confinement. Option B best explains that sense of belonging through familiarity.

The doctor goes up as often as down, so he lives in the middle flat. The professor goes up to meet the IAS officer, so IAS is above professor. The engineer goes up to meet the MLA, and above the MLA lives the professor's friend, the IAS officer. This gives Professor, Engineer, Doctor, MLA, IAS officer from ground to top.

"None but the rich can afford air-travel" means only rich people can travel by air. It does not mean all rich people travel by air or become sick.

Given that electric machines use energy, electricity provides energy, they are cheap to maintain and do not pollute, the reasonable inference is that electrically operated machines are preferable to use. The other options overgeneralize beyond the statements.

Let each glass have volume 1. Milk = 1/2 + 3/4 = 5/4. Water added = 1/2 + 1/4 = 3/4. Ratio milk to water = (5/4):(3/4) = 5:3.

The schedule is Statistics, History, English, Economics, Mathematics from Monday to Friday. Economics is immediately before Mathematics.

The only feasible arrangement is Statistics on Monday, History on Tuesday, English on Wednesday, Economics on Thursday and Mathematics on Friday. Therefore Wednesday is English.

With English immediately before Economics and Mathematics immediately after Economics, and History fixed on Tuesday, the only possible block is Wednesday-English, Thursday-Economics, Friday-Mathematics. So Mathematics is last.

The schedule is Monday Statistics, Tuesday History, Wednesday English, Thursday Economics, Friday Mathematics. History lies between Statistics and English.

History must be Tuesday. English must be immediately before Economics, and Mathematics immediately after Economics; since Economics cannot be Tuesday, the only fit is English-Wednesday, Economics-Thursday, Mathematics-Friday. Thus Monday is Statistics.

The silent revolution is described as transfer of power from upper-caste elites to subaltern groups through democratic public governance. It is not the disappearance of caste/class hierarchies.

The passage says community identity remains a governing force in Indian politics. Therefore democratization has not made community identity irrelevant.

In the Western liberal context, democratization is associated with atomized individuals entering the public sphere. The Indian context differs because people participate through communities and group identities.

The passage says group farming offers scope for enhancing agricultural productivity, so assumption 2 is valid. It does not say transition economies must necessarily have agricultural collectivities.

In context, gender impact refers to whether agricultural collectivities benefit women. The passage contrasts uncertain family cooperative effects with women-only group farming that can benefit women.

The passage says group farming can empower the poor, enhance productivity and protect against free-market individualism. It does not specifically claim surplus production of agricultural commodities.

The shaded quadrants follow a row/column symmetry pattern. The missing centre must complete the arrangement with the right half shaded, matching option D.

Using the three cube views, K is adjacent to A, B, H and M, and B is adjacent to A, K, H and P. The only face that fits opposite A across the cube is H.

The required set is intelligent, honest and truthful but not hardworking, i.e. Q ∩ S ∩ R excluding P. In the labelled Venn diagram this region is numbered 6.

When the cube net is folded, the face marked W becomes opposite the face marked B according to the given hinge arrangement. Hence B is opposite the white face.

A score of 74 is closest to the maximum in Test II, whose range is 45 to 75 and average is 60. Compared with the class spread, 74 is therefore relatively best in Test II.

The sequence moves the triangle around the corners while changing its orientation, and the line rotates/changes position in a parallel pattern. Continuing the same pattern gives the figure shown in option D.

The statement says misuse of nuclear power will trigger the Third World War if it starts. Thus nuclear power would be used in that war. The other options overstate or contradict the conditional statement.

All parked X-brand cars are white, and some of those X-brand cars have radial tyres. Hence some white X-brand cars with radial tyres are parked here. No conclusion follows about non-X cars or manufacturing dates.

A is accepted by W and X only; B by W, Y and Z; C by W, X, Y and Z; D by W and X. Since C is accepted by the most parties, C gets the ticket.

All club members are students. Some club members are married, and all married persons are invited for dance. Therefore those married club members are students invited for dance.

Since only one of A, P and R is open at any one time, at least one road from that set remains open even during storms. The other options assert exact closures not forced by the conditions.

Statement 1 means watching TV implies being bored. Its valid contrapositive is: if I am not bored, I do not watch TV. The other options reverse or add conditions not given.

The passage says effective competition law helps prevent anti-competitive consequences and reassures MNCs that authorities will maintain a level playing field. Therefore option C is the proper inference.

The passage identifies dominance through foreign firms acquiring or forming joint ventures with domestic enterprises and through overseas parent mergers that remove local affiliate independence. Familiarity with domestic law and lower prices are not the stated dominance mechanisms.

The passage says FDI should ideally remain pro-competitive and warns that it may otherwise reduce competition. It does not say foreign investment invariably causes inflated prices.

The passage argues that if development is understood as expansion of human lives and freedoms, democratic rights and political liberties are constitutive elements of development, not merely external links.

The passage says development must be assessed by the lives people can lead and the real freedom they enjoy, not merely GNP, incomes or industrialization. Hence real freedom is the best measure in context.

The passage notes that several East Asian countries achieved strong economic growth without pursuing democracy. It does not conclude that non-democracies always grow faster or that democracy and development are ultimately separate.

The passage says exotic species can reduce endemic species and convert diverse local community compositions into more homogeneous ones. Thus both erosion of endemic species and change in community composition can occur.

Humans influence biodiversity by moving organisms, including illegal transport/smuggling, and by creating transport corridors that breach natural barriers. The statements about preventing new species or ensuring no impact are opposite to the passage.

Natural homogenization is limited by local evolution/adaptation and physical barriers such as oceans and mountain ranges that restrict dispersal. All three listed factors help prevent species from becoming globally uniform.

The passage says humans introduce exotic species intentionally or accidentally for private purposes, public benefit, pest control, agricultural products and recreational opportunities. The listed purposes broadly fit such human motivations, so all three are accepted by the official key.

The passage says introductions do not always reduce biodiversity, not all introduced species greatly alter ecosystems, and homogenization can occur naturally though humans accelerate it. Therefore none of the first three absolute statements is correct.

Ratna scored more than Rani, more than Rama, and more than Padma because Padma is less than Ratna. Hence Ratna scored the highest.

A is B's brother. E is B's daughter and D is E's brother, so D is also B's child. Therefore A, as B's brother, is D's uncle.

The order is Rita prettier than Gita, and Gita prettier than Sita. Therefore Sita is not as pretty as Gita; the other options contradict the stated order.

Let total distance be D. Time for first 60% minus time for remaining 40% is (0.6D - 0.4D)/48 = 10 minutes = 1/6 hour. Thus 0.2D/48 = 1/6, giving D = 40 km.

The statement itself asserts that television is not a luxury item. The other options make broader claims about all expensive or learning-related things that are not logically forced.

The Tamil-speaking doctor is Christian. No two of the same profession speak the same language, so the other doctor speaks Gujarati; no two of the same religion share a profession or language, so that Gujarati doctor is Muslim. The Christian businessman must therefore speak Gujarati.

All five sitcoms that started are still on. Since seven shows remain in all, only two of the five non-sitcom shows (drama and news) survive, meaning three non-sitcom shows were discontinued. As only two news magazines existed, at least one of the discontinued shows must have been a drama.

B wears orange pants, so B cannot wear orange shirt and also cannot wear blue shirt; hence B wears black shirt. A cannot wear black shirt, so A wears blue or orange; C cannot wear orange, leaving C with blue shirt. Pants left for A and C are green and yellow, but A cannot wear green, so C wears green pants.

The information says Ankit hopes to sing and dance at music camp, so it directly supports that he likes or wants to do those activities. It does not prove parental wishes, preference over outdoor activities, or a camp every summer as a general rule.

Only those with binoculars can become members, so membership implies having binoculars. It does not mean everyone with binoculars is a member, nor that all photo-contest participants must be club members.

Statement 1 means A is at least as old as B. Since B is older than C, A must be older than C regardless of whether A equals B or is older than B.

All artists are whimsical, and some artists are drug addicts. Therefore those drug-addict artists are also whimsical, so some drug addicts are whimsical. No conclusion about frustration follows necessarily.

The central theme is that climate adaptation and mitigation must be integrated into development strategies. The other options are partial points or overstatements, not the passage's core argument.

The passage links sustainable growth with human creative adaptation, warns that intensive agriculture can create ecological backlash, and notes that some growth strategies can harm ecology. All three assumptions are valid.

The Aral Sea example criticizes unsuitable irrigated cotton expansion in water-stressed areas, but it does not support a blanket ban on rainfed crops in irrigated areas or on all farming in water-deficient areas. Neither inference follows.

The passage stresses that sustaining growth requires new adaptive technologies and practices and their wide diffusion, which implies research and dissemination. Mere spread of prosperity by itself is not sufficient as a necessary condition.

Low-carbon growth chiefly implies using less carbon-intensive energy, especially renewable energy. Reducing manufacturing, changing to mixed farming, or lowering demand for goods and services is not the meaning given in the passage.

Growth can add vulnerability when it overexploits resources, ignores ecological limits or follows narrow strategies such as unsuitable intensive farming or settlement expansion. The passage gives the Aral Sea and mangrove-clearing examples, supporting the listed vulnerability conditions under the official key.

The passage implies pesticide use has real ecological and resistance problems, so alternatives should be promoted and excessive chemical use is harmful. It does not say improvement is impossible; rather, it calls for better targeted and biodegradable pesticides.

The passage justifies pesticide use in poor countries through food security and epidemic-disease concerns. It does not say developed countries can simply shift to organic farming while poor countries must use pesticides; statement 3 is contextually true but the official key accepts statement 2 only.

Pesticides select resistant individuals because pest populations are genetically variable and some individuals may detoxify pesticides. Resistance is not equally distributed; it spreads because resistant individuals survive and reproduce.

The passage rejects the simple claims that alternatives do not exist, new pesticides are never invented, or pesticides are biodegradable as the reason for continued use. It says continued use is due to favourable cost-benefit and food/health pressures, so none of the listed statements is correct.

The passage gives Alabama leafworm as resistant to many pesticides, supporting statement 3. It does not say pesticides are imperative in all poor countries or that they should have no role at all in sustainable agriculture.

Natural selection means resistant individuals already present or arising in a variable pest population survive pesticide application and become more common. The best implication is that some individuals in a population show resistance after pesticide use.

The passage defines education as an inner process of expansion that creates and sustains self-critical awareness and independence of thought. It is not merely conversion into professionals or acquisition of qualifications.

The passage argues that education must be respected in itself because it develops self-critical awareness, independence of thought and moral-intellectual growth. Employment and mobility are the instrumental view, not the deepest justification.

The instrumentalist view treats education as a means to external ends such as employment, income mobility and trained manpower. Therefore it sees education as functional and utilitarian rather than valuable in itself.
