Q. Private investment in general is volatile. Foreign private investment is more volatile because the available investment avenues are significantly greater (i.e., the entire world).

Q. Private investment in general is volatile. Foreign private investment is more volatile because the available investment avenues are significantly greater (i.e., the entire world).

Therefore, the responsibility of providing employment cannot be left to Foreign Direct investment (FDI). The current FDI inflows are volatile over time and across sectors and regions, which is a necessary consequence of their search for the highest returns. The adverse consequences are unstable employment and an accentuation of income and regional inequalities. A probable positive consequence of foreign investment is the inflow of new technology and its subsequent diffusion. However, the technology diffusion is not at all certain because the existing state of physical and human capital in India may prove inadequate for the diffusion.

Q1. With reference to the above passage, the following assumptions have been made:
1. Relying on foreign investment in the long run is not an economically sound policy.
2. Policies must be undertaken to reduce volatility in foreign private investment.
3. Policies must be undertaken to strengthen domestic private investment.
4. Public investment should be given priority over private investment.
5. Substantial public investment in education and health should be undertaken.
Which of the above assumptions is/are valid?
(a) 1, 2 and 4
(b) 1, 3 and 5
(c) 2, 4 and 5
(d) 3 only
Correct Answer: (b) 1, 3 and 5

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

Statement 3 is correct, the author is stating the general volatility of the private investment; however, he is more critical about foreign direct investment. Hence it can be assumed that the policies must be undertaken to strengthen domestic investment to avoid the volatility of foreign direct investment.
Statement 2 is not correct, from the passage it can be deduced that foreign direct investment has innate nature of volatility and can not be rectified by the adoption of policies.
Statement 1 is correct, as the author is explaining at the start of the passage that foreign investment is volatile further and adverse consequences are unstable employment and an accentuation of income and regional inequalities.
Statement 4 is not correct, public investment is nowhere mentioned in the passage.
Statement 5 is correct, from the last sentence ‘However, the technology diffusion is not at all certain because the existing state of physical and human capital in India may prove inadequate for the diffusion.’ which reflects the inadequate human capital hence we can assume that Substantial public investment in education and health should be undertaken.

Q. Although most of the Genetically Modified (GM) crops cultivated now are genetically engineered for a single trait, in future, crops genetically engineered for more than one trait will be the norm.

Q. Although most of the Genetically Modified (GM) crops cultivated now are genetically engineered for a single trait, in future, crops genetically engineered for more than one trait will be the norm.

Thus, biotechnology’s role in agriculture and the regulation or the same cannot be understood solely in the context of the current generation of GM crops. Instead, there is a need to take a comprehensive look, taking into account various aspects Including socio-economic impacts, so that the potential or the technology can be harnessed while minimizing negative impacts. Given the importance of biotechnology in developing varieties that can help in climate change mitigation and adaptation, not using biotechnology as a part of the climate change action plan cannot be an option. Domestic regulation of biotechnology cannot be viewed in isolation of trade policy and obligations under various international treaties and conventions.

Q1. With reference to the above passage, the following assumptions have been made:
1. Biotechnology regulation is an evolving process.
2. Participation of people is needed in policy decisions regarding biotechnology regulation.
3. Biotechnology regulation should take into account socio-economic aspects in decision-making.
4. Wider involvement of political executive in biotechnology regulation improves its effectiveness in dealing with the country’s trade Policies and international obligations.
Which of the above assumptions are valid?
(a) 1, 2 and 4 only
(b) 1 and 3 only
(c) 2, 3 and 4 only
(d) 1, 2, 3 and 4
Correct Answer: (b) 1 and 3 only

Q2. Which one of the following statements best implies the crux of the passage? 
(a) Precautionary principle is not given importance in current debate on developing GM crops.
(b) Biotechnology is not currently used in climate change mitigation and adaptation mechanisms.
(c) Biotechnology’s role is not confined to the current priorities of developing GM crops.
(d) The negative Impacts of not biotechnology are properly understood.
Correct Answer: (c) Biotechnology’s role is not confined to the current priorities of developing GM crops.

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

Q1 – Statement 1 is correct, the author is talking about the current and upcoming scenario of biotechnology, hence it can be assumed that biotechnology regulation is an evolving process.
Statement 3 is correct, it is clearly mentioned in the passage that ‘there is a need to take a comprehensive look, taking into account various aspects, including socio-economic impacts’. Hence, the socio-economic aspect can also be taken into account in biotechnology regulations.
Statement 2 is not correct, the author has not mentioned anything about people’s involvement in policy regulation.
Statement 4 is not correct, the author is solely talking about the inward-looking nature of the trade policy, from which we can not assume that it is about the wider involvement of political executive.

Q2 – The crux of the passage is that biotechnology has a significant role in developing crop varieties that can help in climate change mitigation and adaptation, and its regulation needs to take into account various aspects, including socio-economic impacts and international treaties and conventions. Therefore, option (c) “Biotechnology’s role is not confined to the current priorities of developing GM crops” is the correct answer.

Q. Asset allocation is the most important investment decision we will ever make, and sadly, most of us do not give that decision the importance it deserves.

Q. Asset allocation is the most important investment decision we will ever make, and sadly, most of us do not give that decision the importance it deserves.

We are adamant about seeking predictability with our future. We tend to think of investing in risky assets as extremely volatile and value eroding. We also dislike fluctuating returns and the loss of control of investment. We think our money is best left idle unproductive but safe. There is no asset that is risk-free. We could lose our jobs, our homes can lose value, our banks can go bankrupt, our bonds can default, the government can collapse and companies we chose fondly may cease to exist. But we cannot live life assuming that all these extreme events are waiting to happen, and all at the same time. All these extreme forms or risks we know will not manifest at the same time.

Q1. Which one of the following statements best implies the suggestion given by the author of the passage?
(a) Distribute your wealth across different kinds of assets so that your risks would be minimized.
(b) Risk-taking behaviour should be a necessary component of your Personality if you want to generate wealth.
(c) While making investments, find a trustworthy asset management organization which would manage your wealth for you.
(d) You should know that investing your money is a risky business.
Correct Answer: (a) Distribute your wealth across different kinds of assets so that your risks would be minimized.

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

(a) Distribute your wealth across different kinds of assets so that your risks would be minimized is the statement that best implies the suggestion given by the author of the passage.

The author highlights that asset allocation is the most important investment decision we will ever make, and that no asset is risk-free. They suggest that while we tend to think of investing in risky assets as extremely volatile and value-eroding, we cannot live life assuming that all extreme risks will manifest at the same time. Therefore, the author implies that it is important to distribute our wealth across different kinds of assets so that our risks would be minimized.

Q. One of the biggest ironies around water is that it comes from rivers and other wetlands.

Q. One of the biggest ironies around water is that it comes from rivers and other wetlands.

Yet it is seen as divorced from them. While water is used as a resource, public policy does not always grasp that it is a part of the natural ecosystem. Efforts at engineering water systems are thus efforts at augmenting water supply rather than strengthening the capacities of ecological systems.

Q1. Which one of the following is the most logical and rational inference that can be made from the above passage?
(a) Rivers and other wetlands should be protected under Ramsar Convention.
(b) Engineering water systems should be modernized and further augmented.
(c) Wetlands need to be reinforced as more than just open sources or water.
(d) Water supply should not be free of cost so as to prevent its misuse or overuse.
Correct Answer: (c) Wetlands need to be reinforced as more than just open sources or water.

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

(c) Wetlands need to be reinforced as more than just open sources or water is the most logical and rational inference that can be made from the passage.

The passage highlights the irony that water comes from rivers and wetlands but is often divorced from them. It suggests that public policy does not always grasp that water is a part of the natural ecosystem and that efforts at engineering water systems are primarily focused on augmenting water supply rather than strengthening the capacities of ecological systems. Therefore, it can be inferred that wetlands need to be reinforced as more than just open sources of water, but also recognized as an integral part of the natural ecosystem. The passage does not suggest that rivers and wetlands should be protected under the Ramsar Convention, that engineering water systems should be modernized and further augmented, or that water supply should not be free of cost to prevent its misuse or overuse.

Q. In India, the current focus on the right to privacy is based on some new realities of the digital age.

Q. In India, the current focus on the right to privacy is based on some new realities of the digital age.

A right is a substantive right only if it works in all situations, and for everyone. A right to free expression for an individual about her exploitation, for instance, is meaningless without actual availability of security that guarantees that private force cannot be used to thwart this right. The role of the State, therefore, is not just to abstain from preventing rightful free Expression, but also to actively ensure that private parties are not able to block it.

Q1. On the basis of the above passage, the following assumptions have been made:
1. State should have some institutions to ensure its appropriate role in a digital society.
2. State should ensure that private parties do not violate the citizens’ right to privacy.
3. Digital economy is not compatible with the idea of not violating the citizens’ privacy.
Which of the above assumptions is/are valid?
(a) 1 and 2
(b) 3 Only
(c) 1 and 3
(d) 2 only
Correct Answer: (a) 1 and 2

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

(a) 1 and 2 are valid assumptions based on the passage.

The passage suggests that the role of the State in a digital age is not just to abstain from preventing rightful free expression but also to actively ensure that private parties are not able to block it. This implies that the State should have institutions to ensure its appropriate role in a digital society and ensure that private parties do not violate citizens’ right to privacy. The passage does not mention anything about assumption 3, which states that the digital economy is not compatible with the idea of not violating citizens’ privacy.

Q. In India, over the last decade or so, labour has been departing agriculture, but is only going to construction and unregistered manufacturing which are not markedly better jobs.

Q. In India, over the last decade or so, labour has been departing agriculture, but is only going to construction and unregistered manufacturing which are not markedly better jobs.

Services, where labour tends to be most productive, are not generating the additional jobs the country needs. India will need 24 million or so jobs over the next decade. The new sector, e-commerce, can at best close only half the jobs gap. Only those sectors that drive domestic demand such as health and education can comfortably fill the other half.

Q1. Which one of the following is best implied in the passage?
(a) Strong measures need to be taken to reduce the rural to urban migration of labour.
(b) The working condition in construction and unregistered manufacturing needs to be improved.
(c) Service sector has been reducing the problem of unemployment.
(d) Increased social sector spending is imperative for large-scale job creation.
Correct Answer: (d) Increased social sector spending is imperative for large-scale job creation.

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

(d) Increased social sector spending is imperative for large-scale job creation is best implied in the passage.

The passage suggests that while labour has been departing agriculture, they are only going to construction and unregistered manufacturing, which are not markedly better jobs. The service sector, where labour tends to be most productive, is not generating the additional jobs the country needs. The passage goes on to state that India will need 24 million or so jobs over the next decade and that only those sectors that drive domestic demand, such as health and education, can comfortably fill the other half of the job gap. This implies that increased social sector spending is imperative for large-scale job creation.

Q. A car travels from a place X to place Y at an average speed of v km/hr from y to X at an average speed of 2v km/hr, again from X to y at an average speed of 3v km/hr and again from y to x at an average speed of 4v km/hr. Then the average speed of the car for the entire journey

Q. A car travels from a place X to place Y at an average speed of v km/hr from y to X at an average speed of 2v km/hr, again from X to y at an average speed of 3v km/hr and again from y to x at an average speed of 4v km/hr. Then the average speed of the car for the entire journey

(a) Is less than v km/hr
(b) Lies between v and 2v km/hr
(c) Lies between 2v and 3v km/hr
(d) Lies between 3v and 4v km/hr
Correct Answer: (b) Lies between v and 2v km/hr

Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

Car travels from place x to y

Given: Car travels from X to Y multiple times
Distance: X to Y = D km
Total journey = 4 legs × D = 4D km

Time taken for each leg:
1. X to Y: D/v hours (speed = v)
2. Y to X: D/(2v) hours (speed = 2v)
3. X to Y: D/(3v) hours (speed = 3v)
4. Y to X: D/(4v) hours (speed = 4v)

Calculations:
1. Total Time = D/v + D/(2v) + D/(3v) + D/(4v)
= (12D + 6D + 4D + 3D)/(12v)
= 25D/(12v) hours

2. Average Speed = Total Distance/Total Time
= 4D/(25D/12v)
= (48/25)v km/hr
≈ 1.92v km/hr

Conclusion:
Since 48/25 is approximately 1.92:
v < (48/25)v < 2v

Therefore, answer is (b): Average speed lies between v and 2v km/hr.

Car travels from place x to y

Q. A car travels from a place X to place Y at an average speed of v km/hr from y to X at an average speed of 2v km/hr, again from X to y at an average speed of 3v km/hr and again from y to x at an average speed of 4v km/hr. Then the average speed of the car for the entire journey Read More »

(a) Rs. 3,60,000
(b) Rs. 3,65,000
(c) Rs. 3,70,000
(d) Rs. 3,75,000
Correct Answer: (d) Rs. 3,75,000

Question from UPSC Prelims 2020 CSAT Paper

Explanation :

A person bought a car and sold it for 3 lakh

Given Information:
– Selling Price (SP) = Rs. 3,00,000
– Loss = 20%
– Therefore, SP = 80% of Cost Price

Solution:
1. Let Cost Price = x

2. We can write:
80% of x = 3,00,000
0.8x = 3,00,000

3. Solving for x:
x = 3,00,000/0.8
x = Rs. 3,75,000

Conclusion: The Cost Price of the car was Rs. 3,75,000. Therefore, answer is (d): Rs. 3,75,000

What is the difference between the maximum share and the minimum share?
(a) Rs. 300
(b) Rs. 350
(c) Rs. 400
(d) Rs. 450
Correct Answer: (c) Rs. 400

Question from UPSC Prelims 2020 CSAT Paper

Explanation :

Sum of 2500 is distributed

Given Information:
Total Amount = 2500
Shares distribution:
– X gets a/2
– Y gets 3a/4
– Z gets 5a/6

Solution:
1. Total shares = a/2 + 3a/4 + 5a/6
= a(6 + 9 + 10)/12
= 25a/12

2. Since total is 2500:
25a/12 = 2500
a = 1200

3. Individual Shares:
X = a/2 = 1200/2 = 600
Y = 3a/4 = 3(1200)/4 = 900
Z = 5a/6 = 5(1200)/6 = 1000

4. Finding Difference:
Maximum share = 1000 (Z’s share)
Minimum share = 600 (X’s share)
Difference = 1000 – 600 = 400

Therefore, the difference between maximum and minimum share is 400.
