Q. In the immediate future, we will see the increasing commodification of many new technologies –

artificial intelligence and robotics, 3D manufacturing, custom made biological and pharmaceutical products, lethal autonomous weapons and driverless cars. This will pose conundrums. The moral question of how a driverless car will decide between hitting jaywalker and swerving and damaging the car has often been debated. The answer is both simple- save the human life- and complex. At which angle should the car swerve- just enough to save the jaywalker or more than enough? If the driverless car is in Dublin, who would take the decision ? The Irish Government, or the car’s original code writer in California, or a software programmer in Hyderabad to whom maintenance is outsourced ? If different national jurisdictions have different fine print on prioritizing a human life, how will it affect insurance and investment decisions, including transnational ones?

Q 1. Which of the following statements best reflect the rational, plausible, and practical implications that can be derived from the passage given above?
1. Too much globalization is not in the best interests of any country.
2. Modern technologies are increasingly blurring the economic borders.
3. Innovation and capital have impinged on the domain of the state.
4. Public policy of every country should focus on developing its own supply chains.
5. Geopolitics will have to reconcile to many ambiguities and uncertainties.
Select the correct answer using the code given below:
(a) 1, 4 and 5 only
(b) 1, 2, 3 and 4 only
(c) 2, 3 and 5 only

Explanation : 

Q1: Correct Answer – (c) 2, 3 and 5 only

Explanation – 1. Too much globalization is not in the best interests of any country: This statement suggests that excessive globalization could have negative consequences for individual countries. However, this idea is not explicitly mentioned or implied in the passage.

2. Modern technologies are increasingly blurring the economic borders: This statement reflects the idea presented in the passage that new technologies such as driverless cars and custom-made biological products can create complex transnational issues that challenge traditional economic boundaries.

3. Innovation and capital have impinged on the domain of the state: This statement reflects the idea presented in the passage that new technologies and their associated capital flows can create complex issues that challenge traditional notions of state sovereignty and control.

4. Public policy of every country should focus on developing its own supply chains: This statement suggests that countries should prioritize developing their own supply chains to mitigate potential negative effects of globalization. However, this idea is not explicitly mentioned or implied in the passage.

5. Geopolitics will have to reconcile to many ambiguities and uncertainties: This statement reflects the idea presented in the passage that new technologies can create complex transnational issues with many ambiguities and uncertainties, which will require adaptation from geopolitical actors.

So based on these explanations, option © 2, 3 and 5 only remains as a correct answer.

Q. Nothing can exist in a natural state,

Q. Nothing can exist in a natural state,

which can be called good or bad by common assent, since every man who is in natural state consults only his own advantage, and determines what is good or bad according to his own fancy and insofar as he has regard for his own advantage alone, and holds himself responsible to no one save himself by any law; and therefore sin cannot be conceived in a natural state, but only a civil state, which is decreed by common consent what is good or bad, and each one holds himself responsible to the state.

Q 1. Which one of the following statements best reflects the central idea of the passage given above?
(a) The conceptions of what is right or wrong exist due to the formation of a state.
(b) Unless a ruling authority decides as to what is right or wrong, no man would be morally right.
(c) Man is inherently immoral and selfish in a natural state.
(d) The idea of what is right or wrong is necessary for the survival of human species.

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (a) The conceptions of what is right or wrong exist due to the formation of a state.

Explanation –

(a) “The conceptions of what is right or wrong exist due to the formation of a state.” This option reflects the central idea of the passage that in a natural state, individuals determine what is good or bad according to their own fancy and sin cannot be conceived. It is only in a civil state where common consent decrees what is good or bad.

(b) “Unless a ruling authority decides as to what is right or wrong, no man would be morally right.” This option suggests that without a ruling authority to determine what is right or wrong, individuals would not be able to act morally. However, this idea is not explicitly stated in the passage.

(c) “Man is inherently immoral and selfish in a natural state.” This option suggests that individuals are inherently immoral and selfish when they are in a natural state. While the passage does mention that individuals consult only their own advantage in a natural state, it does not explicitly state that they are inherently immoral or selfish.

(d) “The idea of what is right or wrong is necessary for the survival of human species.” This option suggests that having an understanding of what is right and wrong is necessary for human survival. However, this idea is not mentioned in the passage.

Q. In our schools, we teach our children all that is there to know no about Physics, maths and history and what-have you.

Q. In our schools, we teach our children all that is there to know no about Physics, maths and history and what-have you.

But do we teach them about the bitter caste divide that plagues the country, about the spectre of famine that stalks large part of our land, about gender sensitivity, about the possibility of atheism as a choice, etc.? Equally important, do we teach them to ask question, or do we teach them only to passively receive our wisdom? From the cocooned world of school, suddenly, the adolescent finds himself/herself in the unfettered world of university. Here he/she is swept up in a turmoil of ideas and influences and ideologies. For someone who has been discouraged from asking questions and forming an opinion, this transition can be painful.

Q 1. Which one of the following best reflects the central idea of the passage given above?
(a) School curriculum is not compatible with the expectations of children and parents.
(b) Emphasis on academic achievements does give time for development of personality and skills.
(c) Preparing the children to be better citizens should be the responsibility of the education system.
(d) To be a better citizen, the present world order demands societal and life-coping skills in addition to academic content.

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (d) To be a better citizen, the present world order demands societal and life-coping skills in addition to academic content.

Explanation – The passage raises concerns about the education system and its focus on academic subjects while neglecting to teach children about important societal issues and life-coping skills. The author argues that children should be taught about the caste divide, famine, gender sensitivity, and atheism as a choice. Additionally, the author suggests that children should be encouraged to ask questions and form their own opinions rather than passively receiving wisdom.

The transition from school to university can be difficult for someone who has not been encouraged to think critically and form their own opinions. In university, students are exposed to a wide range of ideas and ideologies which can be overwhelming for someone who has not been taught to question and think critically.

In summary, the passage argues that schools should do more to prepare children for the world by teaching them about societal issues and life-coping skills in addition to academic content.

Q. Can a democracy avoid being a welfare state for long?

Q. Can a democracy avoid being a welfare state for long?

Why cannot mass welfare be left entirely to the markets? There is a built-in tension between markets and democracy. Markets do not work on a one-person-one-vote principle as democracies do. What one gets out of the market place depends on one’s endowments, skills, purchasing power and the forces of demand and supply. Markets reward individual initiative and skill, and may also lift many from the bottom rungs of society, but some people never get the opportunity to develop skills that markets demand; they are simply too poor and too handicapped; or skill formation takes too long. By creating jobs, markets may be able to help even unskilled people, but capitalism has always witnessed bursts of unemployment.

Q 1. With reference to the above passage, the following assumptions have been made :
1. Modern democracies rely on the market forces to enable them to be welfare states.
2. Markets ensure sufficient economic growth necessary for democracies to be effective.
3. Government programmes are needed for those left behind in economic growth.
Which of the above assumptions is/are valid ?
(a) 1 and 3 only
(b) 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (b) 3 only

Explanation – Based on the information provided in the passage, the valid assumption is (b) 3 only: Government programs are needed for those left behind in economic growth. The passage mentions that markets may lift many from the bottom rungs of society but some people never get the opportunity to develop skills that markets demand and may be left behind. Therefore, government programs may be needed to help these individuals.

Q. Medieval merchants risked the hazards of the Silk Road to reach the markets of China; Portuguese caravels in the 15th century sailed beyond the bounds of the known world, searching less for knowledge than for gold and spices.

Q. Medieval merchants risked the hazards of the Silk Road to reach the markets of China; Portuguese caravels in the 15th century sailed beyond the bounds of the known world, searching less for knowledge than for gold and spices.

Historically, the driver for opening frontiers has always been the search for resources. Science and curiosity are weaker drivers. The only way to open up space, whether the space of solar system or interstellar space is to create an economic engine and that engine is resource extraction.

Q 1. Which one of the following statements best sums up the passage given above?
(a) Wealth generation is the primary motive for any human endeavour.
(b) Space, whether space in solar system or interstellar space, will govern our future economy.
(c) Human beings are motivated to explore new frontiers principally by economic considerations.
(d) Wealth generation is based on the risk-behaviour of some men.

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (c) Human beings are motivated to explore new frontiers principally by economic considerations.

Explanation – The statement that best sums up the passage given above is © Human beings are motivated to explore new frontiers principally by economic considerations. The passage describes how historically, the search for resources has been the primary driver for opening frontiers and exploring new territories. It mentions how medieval merchants risked the hazards of the Silk Road to reach the markets of China and how Portuguese caravels sailed beyond known boundaries in search of gold and spices. The passage also states that science and curiosity are weaker drivers compared to the search for resources and that creating an economic engine through resource extraction is the only way to open up space.

Therefore, based on the information given in the passage, option © Human beings are motivated to explore new frontiers principally by economic considerations best sums up its main idea.

Q. Researchers were able to use stem cells to gauge the neurotoxic effects of the environmental pollutants Bisphenol A (BPA).

Q. Researchers were able to use stem cells to gauge the neurotoxic effects of the environmental pollutants Bisphenol A (BPA).

They used a combination of biochemical and cell-based assays to examines the gene expression profile during the differentiation of mouse embryonic stem cells upon treatment with BPA, a compound known to cause heart diseases, diabetes, and developmental abnormalities in humans. They were able to detect and measure BPA toxicity towards the proper specification of primary germ layers, such as endoderm and ectoderm, and the establishment of neural progenitor cells.

Q 1. On the basis of the passage given above, the following assumptions have been made:
1. BPA may alter embryonic development in vivo.
2. Biochemical and cell-based assays are useful in finding out treatments for pollution-induced diseases.
3. Embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants.
Which of the above assumptions are valid?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (c) 1 and 3 only

Explanation – Based on the information given in the passage, assumptions 1 and 3 are valid. The passage states that BPA is known to cause developmental abnormalities in humans and that researchers were able to detect and measure BPA toxicity towards the proper specification of primary germ layers during embryonic development. This supports assumption 1 that BPA may alter embryonic development in vivo. The passage also mentions that researchers used stem cells to gauge the neurotoxic effects of BPA and were able to establish neural progenitor cells. This supports assumption 3 that embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants.

However, there is no information given in the passage to support assumption 2 that biochemical and cell-based assays are useful in finding out treatments for pollution-induced diseases. While these assays were used to examine gene expression profiles during differentiation upon treatment with BPA, there is no mention of their use in finding treatments for pollution-induced diseases.

Therefore, based on the information given in the passage, assumptions 1 and 3 are valid while assumption 2 is not supported by evidence from the text.

Q. Researchers were able to use stem cells to gauge the neurotoxic effects of the environmental pollutants Bisphenol A (BPA). Read More »

Q. A study conducted on the impacts of climate change over the Cauvery basin of Tamil Nadu using regional climate models showed an increasing trend for maximum and minimum temperatures, and a decrease in the number of rainy days.

These climatic shifts will have an impact on the hydrological cycles in the region, lead to more run-off and less recharge, and affect the groundwater tables. Further, there has been an increase in the frequency of droughts in the State. This has driven farmers to increase dependency on groundwater resources to secure their crops.

Q 1. Which one of the following statements best reflects the crux of the passage given above?
(a) Development of regional climate models helps in choosing climate-smart agricultural practices.
(b) Heavy dependence on groundwater resources can be reduced by adopting dry-land cropping systems.
(c) Climate changes increase the criticality of water resources while simultaneously threatening it.
(d) Climate changes cause the farmers to adopt unsustainable livelihoods and risky coping strategies.

Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

Q1: Correct Answer – (c) Climate changes increase the criticality of water resources while simultaneously threatening it.

Explanation – (a) Development of regional climate models helps in choosing climate-smart agricultural practices. This statement is not directly supported by the passage. While regional climate models may help in understanding the impacts of climate change and choosing appropriate agricultural practices, this is not mentioned in the passage.
