Not every voice on the internet commands the same kind of audience. When anonymous private entities with high capital can pay for more space for their opinions, they are effectively buying a louder voice. If political discourse in the digital sphere is a matter of outshining one’s opponent till the election is won, then the quality of politics suffers. The focus of social media is restricted to the promotion of content that generates more user engagement, regardless of how inflammatory the content may be.
Which one of the following statements best reflects the central idea of the above passage?
Answer (b) & explanation
The central idea is that social media are profit-making products, not moral institutions (b). Step 1: the passage says rich entities can pay for space and buy "a louder voice". Step 2: it also says platforms push content that brings engagement, "regardless of how inflammatory" it is. Both show a business that seeks profit, not fairness. Step 3: options (a), (c) and (d) praise social media (instant information, stronger democracy, a necessary part of life). The passage is critical, so they fail.
Tip: first decide the tone of the passage: positive or critical. Then drop every option with the opposite tone. This one passage is critical throughout.

Not every voice on the internet commands the same kind of audience. When anonymous private entities with high capital can pay for more space for their opinions, they are effectively buying a louder voice. If political discourse in the digital sphere is a matter of outshining one’s opponent till the election is won, then the quality of politics suffers. The focus of social media is restricted to the promotion of content that generates more user engagement, regardless of how inflammatory the content may be.
Based on the above passage, the following assumptions have been made :
- 1. Internet is not inclusive enough.
- 2. Internet can adversely affect the quality of politics in a country.
Which of the assumptions given above is/are valid?
Answer (c) & explanation
Both assumptions are valid (c). Step 1: the passage opens: "Not every voice on the internet commands the same kind of audience." Rich players can buy a louder voice. So the internet is not equally open to all, that is, not inclusive enough (1). Step 2: it says that if online politics is just about outshining opponents, "the quality of politics suffers." So the internet can harm politics (2). Step 3: both ideas sit directly in the text, so options (a), (b) and (d) fail.
Tip: when a statement closely restates a line in the passage, it is valid. Underline key lines while reading. "Inclusive" means giving everyone a fair chance to be heard.

Read the passage
We take it for granted now that science has a social responsibility. The idea would not have occurred to Newton or Galileo. They thought of science as an account of the world as it is, and the only responsibility that they acknowledged was to tell the truth. The idea that science is a social enterprise is modern, and it begins at the industrial revolution. We are surprised that we cannot trace a social sense further back, because we nurse the illusion that the industrial revolution ended a golden age.
Which one of the following statements best reflects the thinking of the author about the science?
Answer (d) & explanation
The author thinks science must pursue truth and also serve society (d). Step 1: the passage says Newton and Galileo saw science's only duty as "to tell the truth". Step 2: it adds that today "we take it for granted" that science has a social responsibility, an idea that began with the industrial revolution. Joining both gives (d). Step 3: option (c) reverses the link: the passage says the social sense began at the industrial revolution, not that science caused it. Options (a), scientists' commitment, and (b), scientific awareness, are not discussed.
Tip: when a passage moves from an old view to a new one, the best answer often joins both. India's Constitution (Article 51A) lists developing scientific temper as a fundamental duty.
Answer as per the official UPSC answer key.
Read the passage
“The history of science is the real history of mankind.” In this striking epigram, a nineteenth-century writer links science with its background. Like most epigrams, its power lies in emphasizing by contrast an aspect of truth which may be easily overlooked. In this case, it is easy to overlook the relations between science and mankind, and to treat the former as some abstract third party, which can sometimes be praised for its beneficial influences, but frequently and conveniently blamed for the horrors of war. Science and mankind cannot be divorced from time to time at men’s convenience. Yet we have seen that, in spite of countless opportunities of improvement, the opening years of the present period of civilization have been dominated by international conflict. Is this the inevitable result of the progress of science or does the fault lie elsewhere?
Which of the following is/are emphatically conveyed by the author of the passage?
- 1. Without science, mankind could not have continued to exist till today.
- 2. It is the science that will ultimately determine the destiny of mankind.
Select the correct answer using the code given below.
Answer (d) & explanation
Neither statement is conveyed (d). Step 1: the author's main point is that science and mankind "cannot be divorced"; science is part of human history, not a separate "third party". Step 2: statement 1 says mankind could not have survived without science. The passage never says this. Statement 2 says science will decide mankind's destiny. The passage does not say this either. Step 3: in fact, the last question, "does the fault lie elsewhere?", hints that people, not science, may be to blame for wars. So options (a), (b) and (c) fail.
Tip: "emphatically conveyed" means the author clearly says it. Big claims like survival or destiny must be in the text, not just possible.

Read the passage
Sourcing food from non-agricultural lands (uncultivated systems such as forests, wetlands, pastures, etc) in addition to agricultural lands enables a systemic approach to food consumption. It allows rural and tribal communities to sustain themselves for the whole year and steer clear of natural disasters and season-induced shortfalls of agricultural food. Since the productivity of trees is often more resilient to adverse weather conditions than annual crops, forest foods often provide a safety net during periods of food shortages caused by crop failure; forest foods also make important contributions during seasonal crop production gaps.
Which one of the following statements best reflects the most logical and rational message conveyed by the author of the passage ?
Answer (d) & explanation
The message is that agroecosystems should be developed along with conventional agriculture (d). Step 1: the passage says sourcing food from forests, wetlands and pastures "in addition to agricultural lands" helps communities all year. Step 2: forest foods act as a safety net when crops fail. They supplement farming, not replace it. That is (d). Step 3: option (a) says food trees should replace other trees, and option (b) says conventional farming cannot ensure food security; both overreach. Option (c), converting wastelands, is not mentioned.
Tip: "in addition to" is the key phrase. Reject options that turn "addition" into "replacement".

While awareness on use/misuse and abuse of antibiotics is common knowledge, as is the impact of dosing poultry with antibiotics, the environmental impact of antibiotics-manufacturing companies not treating their waste has scarcely been discussed at any length or seriousness thus far. Pollution from antibiotics factories is fuelling the rise of drug-resistant infections. The occurrence of drug-resistant bacteria surrounding the pharma manufacturing plants is well known.
Which one of the following statements best reflects the most logical and practical message conveyed by the passage ?
Answer (a) & explanation
The practical message is that proper effluent treatment protocols are needed (a). Step 1: the passage says antibiotic factories "not treating their waste" is fuelling drug-resistant infections. Step 2: the direct fix for untreated waste is proper treatment protocols. That is (a). Step 3: option (b), awareness, is already "common knowledge" as the passage says. Option (c) calls the problem unavoidable, which the passage does not say. Option (d), moving plants to rural areas, only shifts the harm elsewhere.
Tip: the most practical solution attacks the exact cause named. Antimicrobial resistance (AMR) is a key global health threat; India runs a National Action Plan on AMR.

Benefits of good quality school education accrue only when students complete and leave school after having acquired the gateway skills. Like one learns to walk before running, similarly one picks up advanced skills only after picking the basic foundational skills. The advent of the knowledge economy poses new challenges, and one of the severe consequences of having an uneducated workforce will be our inability to keep pace with the global economy. Without a strong learning foundation at the primary level, there can be no improvement in higher education or skill development.
Which one of the following statements best reflects the crux of the passage ?
Answer (a) & explanation
The crux is that to become a global power, India must invest in universal quality education (a). Step 1: the passage says advanced skills come only after foundational skills, as one walks before running. Step 2: an uneducated workforce would leave India unable to keep pace with the global economy. So universal quality schooling is the base. That is (a). Step 3: option (c) focuses on higher education, which reverses the passage's order. Option (b) says India is unable to become a power, which is too strong. Option (d), illiterate parents, is not mentioned.
Tip: India's NEP 2020 and NIPUN Bharat Mission stress foundational literacy and numeracy by Grade 3, the same idea as this passage.

Read the passage
In India, while the unemployment rate is a frequently used measure of poor performance of the economy, under conditions of rising school and college enrolment, it paints an inaccurate picture. The reported unemployment rate is dominated by the experience of younger Indians who face higher employment challenges and exhibit greater willingness to wait for the right job than their older peers. The unemployment challenge is greater for people with secondary or higher education, and rising education levels inflate unemployment challenges.
Which one of the following statements most likely reflects as to what the author of the passage intends to say ?
Answer (b) & explanation
The author says unemployment should be seen in light of rising education and aspirations of young Indians (b). Step 1: the passage says the unemployment rate paints an inaccurate picture when school and college enrolment are rising. Step 2: young, educated Indians are more willing to "wait for the right job", and rising education "inflates" unemployment. So it reflects education and aspirations. That is (b). Step 3: option (a), quality of education, and option (c), labour-intensive industry, are not discussed. Option (d), self-employment, is not suggested.
Tip: this is "aspirational unemployment". Educated youth may wait for a suitable job rather than take any job.

Read the passage
“Science by itself is not enough, there must be a force and discipline outside the sciences to coordinate them and point to a goal. It is not possible to run a course aright when the goal itself has not been rightly placed. What science needs is philosophy — the analysis of scientific method and the coordination of scientific purposes and results; without this, any science must be superficial. Government suffers, precisely like science, for lack of philosophy. Philosophy bears to science the same relationship which statesmanship bears to politics : movement guided by total knowledge and perspective, as against aimless and individual seeking. Just as the pursuit of knowledge becomes scholasticism when divorced from the actual needs of men and life, so the pursuit of politics becomes a destructive bedlam when divorced from science and philosophy.”
Which one of the following statements best reflects the most rational, logical and practical message conveyed by the passage ?
Answer (b) & explanation
The message is that government should not be run only by practical statesmen, but with people of learning and wisdom (b). Step 1: the passage says science needs philosophy to give it a goal. Step 2: it says government suffers "like science, for lack of philosophy". Politics without science and philosophy becomes "destructive bedlam". So practical statesmen need learned, wise people alongside. That is (b). Step 3: options (a) and (c) prescribe training schemes the passage never proposes. Option (d), all scientists as philosophers, is too absolute.
Tip: this passage is from Will Durant on Plato. Pick the option that applies the passage's comparison (science-philosophy, politics-statesmanship) to government.

Read the passage
“The last end of the state is not to dominate men, nor to restrain them by fear; rather it is so to free each man from fear that he may live and act with full security and without injury to himself or his neighbour. The end of the state, I repeat, is not to make rational beings into brute beasts and machines. It is to enable their bodies and their minds to function safely. It is to lead men to live by, and to exercise, a free reason; that they may not waste their strength in hatred, anger and guile, nor act unfairly toward one another.”
Based on the above passage, which one of the following terms best expresses the ultimate goal of the state ?
Answer (d) & explanation
The ultimate goal of the state is liberty (d). Step 1: the passage says the state's end is "not to dominate men" but to "free each man from fear". Step 2: it adds that the state should lead men to live by and use "a free reason". Freedom runs through every line. That is (d). Step 3: option (a), personal safety, and option (b), health of body and mind, are only parts of this freedom. Option (c), communal harmony, is a side effect at most.
Tip: this is Spinoza's view: "the end of the state is really liberty". Pick the term that sums up all the lines, not one detail.

Read the passage
In India, a majority of farmers are marginal and small, less educated and possess low adaptive capabilities to climate change, perhaps because of credit and other constraints. So, one cannot expect autonomous adaptation to climate change. Even if it was possible, it would not be sufficient to offset losses from climate change. To deal with this, adaptation to climate change is paramount, alongside a fast mitigation response. Another solution is to have a planned or policy-driven adaptation, which would require the government to come up with policy recommendations. Perception is a necessary pre-requisite for adaptation. Whether farmers are adapting agricultural practices to climate change depends on whether they perceive it or not. However, this is not always enough for adaptation. It is important how a farmer perceives the risks associated with climate change.
Which one of the following statements best reflects the most logical and rational message conveyed by the author of the passage ?
Answer (c) & explanation
The message is that farmers' risk perceptions matter for motivating adaptation (c). Step 1: the passage says perception is a "necessary pre-requisite" for adaptation. Step 2: it ends with its key point: "It is important how a farmer perceives the risks" of climate change. That is (c). Step 3: option (a) says adaptation is only the government's job; the passage mentions policy as just one solution. Option (b) is not discussed. Option (d) says mitigation is not possible, but the passage calls for "a fast mitigation response".
Tip: the last line of a passage often carries its main message. Check options with "only" or "not possible" against the text.

Read the passage
The emissions humans put into the atmosphere now will affect the climate in the middle of the century and onwards. Technological change, meanwhile, could make a future transition away from fossil fuels cheap or it might not, leaving the world with a terrible choice between sharply reducing emissions at huge cost or suffering through the effects of unabated warming. Businesses that do not hedge against the threat of uncertain outcomes fail. The world cannot afford such recklessness on climate change.
Which one of the following statements best reflects the crucial message conveyed by the author of the passage ?
Answer (c) & explanation
The crucial message is that waiting for better technology before cutting emissions is unwise (c). Step 1: the passage says today's emissions will affect the climate from mid-century. Step 2: technology "could make a future transition cheap or it might not". Betting on it is reckless, like a business that fails to hedge. So act now. That is (c). Step 3: option (b) makes technology the only solution, the very gamble the author warns against. Option (a), closing businesses, and option (d), only renewable industries, are not argued.
Tip: when an author says "it might not", he is warning against relying on it. Pick the option that rejects waiting.

Read the passage
Many people are not eating the right food. For some, it is simply a decision to stick with food they enjoy but which is not too healthy. This is leading to an increase in non-communicable diseases. This in turn leads to major burden on our health-care systems that have the potential to derail the economic progress which is essential for the poor to improve their lives. For others, it is about limited access to nutritious food or a lack of affordability, leading to monotonous diets that do not provide the daily nutrients for them to develop fully. Part of the reason nutrition is under threat worldwide is that our food systems are not properly responding to nutritional needs. Somewhere along that long road from farm to fork, there are serious detours taking place.
Which one of the following statements best reflects the crux of the passage ?
Answer (b) & explanation
The crux is that food-based nutrition must be at the centre of policy debate (b). Step 1: the passage says many people eat unhealthy food, which raises non-communicable diseases. Others lack access to nutritious food. Step 2: it says our food systems are not responding to nutritional needs, with "detours" from farm to fork. So nutrition must come first in food policy. That is (b). Step 3: option (a), Universal Basic Income, is not mentioned. Options (c) GM crops and (d) food fortification are specific fixes the passage does not propose.
Tip: the crux is the broad idea the passage builds to. Options naming specific technologies are usually too narrow.

Read the passage
Along with sustainable lifestyles, climate justice is regarded as a significant principle in environmental parlance. Both the principles have bearings on political and economic choices of the nation. So far, in our climate change summits or compacts, both the principles have eluded consensus among nations. Justice, in the judicial sense, is well defined. However, in the context of climate change, it has scientific as well as socio-political connotations. The crucial question in the next few years will be how resources, technologies and regulations are used to support the victims of climate change. Justice in climate is not confined to actions relating to mitigation, but includes the wider notion of support for adaptation to climate change and compensation for loss and damage.
Which one of the following statements best reflects the most logical, rational and crucial message conveyed by the passage ?
Answer (a) & explanation
The crucial message is that climate justice should be built in detail into the rules of new climate agreements (a). Step 1: the passage says climate justice has "eluded consensus" in climate summits. Step 2: it says justice covers not just mitigation but also adaptation support and loss and damage. These need to be spelled out in agreements. That is (a). Step 3: option (b), uneven resources, and option (c), climate refugees, are not the main point. Option (d) blames developed countries, which the passage does not state.
Tip: a Loss and Damage Fund was agreed at COP27 (2022) and made operational at COP28 (2023). It is a step toward the climate justice this passage discusses.

Read the passage
With steady economic growth, higher literacy and increasing skill levels, the number of Indian middle-class families has gone up exponentially. Direct results of the affluence have been changes in dietary patterns and energy consumption levels. People have moved to a higher protein-based diet like milk products, fish and meat, all of which need significantly more water to produce than cereal-based diets. Increasing use of electronic and electric machines/gadgets and motor vehicles needs more and more energy and generation of energy needs water.
Which one of the following statements best reflects the crux of the passage?
Answer (d) & explanation
The crux is that India's water management must change dramatically (d). Step 1: the passage says growing affluence changed diets toward milk, fish and meat, which need much more water than cereals. Step 2: it says more gadgets and vehicles need more energy, and making energy needs water. Both changes push water demand up, so water management must change. That is (d). Step 3: option (a) asks people to go back to cereal diets, which the passage does not suggest. Option (b) misses water. Option (c) is too general.
Tip: find the common thread in the examples. Diet and energy both lead to one word here: water.
Answer as per the official UPSC answer key.
Read the passage
The main threat to maintaining progress in human development comes from the increasingly evident unsustainability of production and consumption patterns. Current production models rely heavily on fossil fuels. We now know that this is unsustainable because the resources are finite. The close link between economic growth and greenhouse gas emissions needs to be severed for human development to become truly sustainable. Some developed countries have begun to alleviate the worst effects by expanding recycling and investing in public transport and infrastructure. But most developing countries are hampered by the high costs and low availability of clean energy sources. Developed countries need to support developing countries’ transition to sustainable human development.
Unsustainability in production pattern is due to which of the following?
- 1. Heavy dependence on fossil fuels
- 2. Limited availability of resources
- 3. Expansion of recycling
Select the correct answer using the code given below.
Answer (a) & explanation
Statements 1 and 2 are the causes (a). Step 1: the passage says current production "relies heavily on fossil fuels" (1). Step 2: it says this is unsustainable "because the resources are finite", meaning limited (2). Step 3: recycling appears as something developed countries do to reduce the harm. It is a remedy, not a cause, so statement 3 fails. That rules out options (c) and (d). Option (b) misses statement 1.
Tip: in cause questions, separate the problem from the cure. A passage often mentions both, and UPSC places the cure among the causes as a trap.

Read the passage
For two or three generations past, ever-increasing numbers of individuals have been living as workers merely, not as human beings. An excessive amount of labour is rule today in every circle of society, with the result that man’s spiritual element cannot thrive. He finds it very difficult to spend his little leisure in serious activities. He does not want to think; or he cannot even if he wants to. He seeks not self-improvement, but entertainment which would enable him to be mentally idle and to forget his usual activities. Therefore, the so-called culture of our age is dependant more on cinema than on theatre, more on newspapers, magazines and crime stories than on serious literature.
The passage is based on the idea that
Answer (b) & explanation
The passage is based on the idea that overstrain is the great evil of our age (b). Step 1: the passage says "an excessive amount of labour" is the rule today. Step 2: everything else follows from this: man's spiritual side cannot grow, he has little leisure, and he seeks only entertainment. So overwork is the root idea. That is (b). Step 3: option (a), man should not work hard, overstates it; the problem is excess. Options (c) and (d) are effects of overwork, not the main idea.
Tip: separate the root cause from its effects. The base idea is the cause the author keeps returning to.

The main threat to maintaining progress in human development comes from the increasingly evident unsustainability of production and consumption patterns. Current production models rely heavily on fossil fuels. We now know that this is unsustainable because the resources are finite. The close link between economic growth and greenhouse gas emissions needs to be severed for human development to become truly sustainable. Some developed countries have begun to alleviate the worst effects by expanding recycling and investing in public transport and infrastructure. But most developing countries are hampered by the high costs and low availability of clean energy sources. Developed countries need to support developing countries’ transition to sustainable human development.
Consider the following statements :
Developed countries can support developing countries’ transition to sustainable human development by
- 1. making clean energy sources available at low cost
- 2. providing loans for improving their public transport at nominal interest rates
- 3. encouraging them to change their production and consumption patterns
Which of the statements given above is/are correct?
Answer (b) & explanation
Statements 1 and 2 are correct (b). Step 1: the passage says developing countries face "high costs and low availability of clean energy". So making clean energy cheap and available helps them (1). Step 2: it says developed countries have eased harm by investing in public transport. Low-interest loans for this are real support (2). Step 3: statement 3, merely encouraging change, gives no material help. The passage asks developed countries to "support" the transition. So options (a), (c) and (d) fail.
Tip: "support" in such passages means money, technology or cheaper access. Advice alone is not support. India's climate stance also stresses finance and technology transfer from developed nations.

Man does not seek self-improvement because he
Answer (d) & explanation
Man does not seek self-improvement because he loves amusement and is mentally idle (d). Step 1: the passage says he seeks "not self-improvement, but entertainment which would enable him to be mentally idle". That is (d). Step 2: option (b) says he has no time. But the passage says he has "little leisure", not none. Step 3: option (a), lack of intellect, is not said; the passage says he does not want to think. Option (c), materialism, is not mentioned.
Tip: "little" is not "no". UPSC often swaps a mild word in the passage for an absolute one in the options.
Answer as per the official UPSC answer key.
Read the passage
Unless the forces and tendencies which are responsible for destroying the country’s environment are checked in the near future and afforestation of denuded areas is taken up on a massive scale, the harshness of the climatic conditions and soil erosion by wind and water will increase to such an extent that agriculture, which is the mainstay of our people, will gradually become impossible. The desert countries of the world and our own desert areas in Rajasthan are a grim reminder of the consequences of large-scale deforestation. Pockets of desert-like landscape are now appearing in other parts of the country including the Sutlej-Ganga Plains and the Deccan Plateau. Where only a few decades back there used to be lush green forests with perennial streams and springs, there is only brown earth, bare of vegetation, without any water in the streams and springs except in the rainy season.
According to the passage given above, deforestation and denudation will ultimately lead to which of the following?
- 1. Depletion of soil resource
- 2. Shortage of land for the common man
- 3. Lack of water for cultivation
Select the correct answer using the code given below.
Answer (c) & explanation
Statements 1 and 3 are the outcomes (c). Step 1: the passage warns of "soil erosion by wind and water", which depletes the soil (1). Step 2: it describes streams and springs without water except in the rains. So water for farming runs short (3). Step 3: a shortage of land for the common man (2) is never mentioned. The passage talks of land turning to desert, not of people lacking land. So options (a), (b) and (d) fail.
Tip: deforestation leads to desertification. Note the passage's examples: Rajasthan's desert, and pockets of desert-like land in the Sutlej-Ganga plains and the Deccan.
