1
CSAT (Aptitude)

Passage-1 Human history abounds in claims and theories confining the right of governing to a few select citizens. Exclusion of the many is justified on the ground that human beings may be rightfully segregated for the good of society and viability of the political process. Which one of the following statements is least essential as a part of the argument in the above passage ?

  1. A.Man seeks control over external things affecting him.
  2. B.In society, there are ‘super’ and ‘sub’ human beings.
  3. C.Exceptions to universal citizen participation are conducive to systemic efficacy.
  4. D.Governing implies recognition of disparities in individual capacities.

Explanation

All human beings are not equal. Some have capabilities to govern while others are inclined to be governed by others due to their subservient qualities. This segregation is good for society. This obviates the unnecessary conflict. Hence, this leads to efficiency in governance. Based on the explanation given above, it is correct to say that society is divided into a ‘super’ and ‘sub’ human beings. Option (b) is relevant and important implication based on the passage. Option (c) is right in upholding the exception to equal rights of all the citizens in society. This division is essential for efficiency. It is the most important part of the argument. Option (d) is also incoherent with the passage. It simplifies the message of the author in the passage. Hence, this is not the least important message. Option (a) is out of the scope of the passage. It is not related to the ongoing argument that focuses on the division of society on basis of competencies. Hence, it is the most appropriate answer choice.

CSAT (Aptitude)

Passage-2 By 2050, the Earth’s population will likely have swelled from seven to nine billion people. To fill all those stomachs — while accounting for shifting consumption patterns, climate change, and a finite amount of arable land and potable water — some experts say food production will have to double. How can we make the numbers add up ? Experts say higher yielding crop varieties and more efficient farming methods will be crucial. So will waste reduction. Experts urge cities to reclaim nutrients and water from waste streams and preserve farmland. Poor countries, they say, can improve crop storage and packaging and rich nations could cut back on resource-intensive foods like meat. Which one of the following statements best sums up the above passage ?

  1. A.The population of the world is growing very fast.
  2. B.Food security is a perennial problem only in developing countries.
  3. C.The world does not have enough resources to meet the impending food scarcity.
  4. D.Food security is increasingly a collective challenge. UPSC CIVIL SERVICES EXAMINATION (PRELIMS)-CSAT

Explanation

Statement (a) is not the best point that the author is trying to make throughout this passage. The population is growing at a fast pace. But the main point is the problems associated with it which are missing in this option. Statement (b) limits the problem of food security to only developing countries which is not true according to the passage. So, it can be neglected. Statement (c) does not find support from the passage. Nowhere, the passage mentions that resources are not available to meet the increasing demand. The passage says that the population is increasing and hence to feed such big numbers food production has to be increased. With the limited arable land and potable water, it is a challenge for the world community.

CSAT (Aptitude)

Passage-3 Many people in India feel that if we cut our defense expenditure on weapon-building, we can create a climate of peace with our neighbours, subsequently reducing the conflict or creating a no-war situation. People who proclaim such ideas are either the victims of war or the propagators of false argument. With reference to the above passage, which of the following is the most valid assumption ?

  1. A.Building of weapons systems by us has instigated our neighbours to wage wars against us.
  2. B.The greater spending on weapon-building by us would lessen the possibility of armed conflict with our neighbours.
  3. C.It is necessary to have state of the art weapons systems for national security.
  4. D.Many people in India believe that we are wasting our resources on weapon- building.

Explanation

Statement (a) seems to be an illogical assumption. If a country is having a small armoury and it is vulnerable to foreign attacks; then all the small countries shall have been merged with the big countries. Moreover, this statement is not supported by the passage. Statement (b) finds relevance with the views of the author in the passage. The passage suggests the reduction of weapon building to create an environment of peace and trust. This is a good step to build trust in neighbouring countries. This is the best assumption based on the passage. Statement (c) is against the spirit of the passage. Statement (d) is not an assumption; it is a stated fact in the passage.

CSAT (Aptitude)

Passage-4 India accounts for nearly a fifth of the world’s child deaths. In terms of numbers, it is the highest in the world — nearly 16 lakhs every year. Of these, more than half die in the first month of life. Officials believe that the reason for this is the absence of steps to propagate basic health practices relating to breast feeding and immunisation. Also, the large reproductive population of 2.6 crore remains bereft of care during the critical phases of pregnancy and post-delivery. Added to this is the prevalence of child marriages, anaemia among young women and lack of focus on adolescent sanitation, all of which impact child death rates. Which is the critical inference that can be made from the above passage ?

  1. A.A lot of Indians are illiterate and hence do not recognize the value of basic health practices.
  2. B.India has a very huge population and the government alone cannot manage public health services.
  3. C.Universalization and integration of maternal health and child health services can effectively address the problem.
  4. D.The nutrition of women in child bearing age does not affect child mortality rate.

Explanation

Use the elimination strategy to solve this question. Statement (c) is the least relevant. The author has not recommended that people shall help the government in solving the problem of poor public health service. Statement (d) is totally against the content of the passage. According to the passage, the health of the mother is very important for the health of a newly born child. Statement (a) is next to be eliminated as even though ignorance is the major reason for poor health conditions the literate might also be getting the services of poor public health systems. Hence, this statement is an incomplete one and not a correct inference. Statement (c) best captures the essence of the passage. It is a correct inference based on the facts of the passage. This correctly connects maternal health and child care health services in the public health care services.

Passage-5 Foods travel more than the people who eat them. Grocery stores and supermarkets are loaded with preserved and processed foods. This, however, often leads to environmental threats, such as pollution generated by long distance food transportation and wastage of food during processing and transportation, destruction of rain forests, reduced nutritional content, increased demand for preservation and packaging. Food insecurity also increases as the product comes from regions that are not feeding their own population properly. With reference to the above passage, which of the following statements is/are true ? 1. Consuming regionally grown food and not depending on long travelled food is a part of eco-friendly behaviour. 2. Food processing industry puts a burden on our natural resources. Select the correct answer using the code given below:

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2

Explanation

Statement 1 is correct. It is very beneficial to consume locally grown food as it will be easily and sufficiently available . It promotes healthy eating habits . It is also eco-friendly. Statement 2 is correct. Large-scale food processing leads to overproduction, an increase in demand for preservation and wastages that subsequently leads to a burden on the natural resources.
