Q1502. With reference to the National Investment Fund to which the disinvestment proceeds are routed, consider the following statements: 1. The assets in the National Investment Fund are managed by the Union Ministry of Finance. 2. The National Investment Fund is to be maintained within the Consolidated Fund of India. 3. Certain Asset Management companies are appointed as the fund managers. 4. A certain proportion of annual income is used for financing select social sectors. Which of the statements given above is/are correct?
Explanation
The National Investment Fund (NIF) was created in India to receive the proceeds from the disinvestment of public sector undertakings (PSUs). The idea was to use these funds strategically for social sector development and investment.
Statement 1 is incorrect: the NIF’s assets were managed by selected public sector mutual funds, namely UTI Asset Management Company Ltd., SBI Funds Management Private Ltd., and LIC Mutual Fund Asset Management Company Ltd., not directly by the Union Ministry of Finance.
Statement 2 is incorrect: The NIF was kept outside the Consolidated Fund of India. This was done to ensure that the disinvestment proceeds were used for their intended purpose (social sector development) and not simply absorbed into general government expenditure.
Statement 3 is correct: The Government appoints Asset Management Companies (AMCs) from the public sector to manage the fund.
Statement 4 is correct: 75% of the annual income from NIF is allocated to social sector schemes (education, health, employment). 25% is used for capital investment in profitable/ revivable CPSEs to support their expansion and diversification.

Q1503. A great deal of Foreign Direct Investment (FDI) to India comes from Mauritius than from many major and mature economies like the UK and France. Why?
Explanation
India receives significant FDI from Mauritius primarily due to the Double Taxation Avoidance Agreement (DTAA) between the two countries. DTAA is a tax treaty that prevents individuals/entities from being taxed twice on the same income. It promotes cross-border investments by offering tax relief. Historically, this agreement allowed Mauritius-based investors to route investments into India with tax benefits, leading to higher FDI flows compared to countries like the UK and France. India has DTAA with several countries, including Mauritius, Singapore, USA, UK, Germany, Japan, Canada, France, Australia, Netherlands, China, and Bangladesh. India does not have DTAA with Afghanistan, Iraq, and Pakistan.

Q1504. Tamil Nadu is a leading producer of mill-made cotton yarn in the country. What could be the reason? 1. Black cotton soil is the predominant type of soil in the State. 2. Rich pool of skilled labour is available. Which of the above is/are the correct reasons?
Explanation
Tamil Nadu is a leading producer of mill-made cotton yarn in India due to the availability of a rich pool of skilled labor, which is crucial for operating the state’s large textile industry. The state has a long tradition of textile manufacturing, supported by well-developed infrastructure and favorable government policies.
Statement 1 is incorrect: Black cotton soil is often considered ideal for cultivating cotton because of its moisture-retaining properties. However, this soil type is not predominant in Tamil Nadu. Instead, black cotton soil is commonly found in states like Maharashtra, Gujarat, and Madhya Pradesh. The cotton used in Tamil Nadu’s mills is primarily sourced from these cotton-growing regions, rather than being grown locally on black cotton soil.
Statement 2 is correct: Tamil Nadu has a long-established tradition in textile manufacturing. The state is renowned for its skilled and semi-skilled workers who efficiently manage complex mill operations, machinery, and quality control. This expertise is one of the major reasons behind its leading position in the cotton yarn industry.

These reserves focus on both species and ecosystems in a sustainable manner, including human communities. They aim for ecological conservation, research, and sustainable use of natural resources.
Statement 3 is correct: In Wildlife Sanctuaries, human activity and biotic interference are allowed in certain circumstances, like grazing or collection of non-timber forest products, as long as they do not harm the wildlife or environment. The level of interference is regulated based on the sanctuary’s management plan.

The Convention’s mission is to support the conservation and wise use of wetlands through local, national, and international efforts to achieve sustainable devel-opment globally.

UPSC 2010Indian Economy · Banking Sector in India
Q1510. When the Reserve Bank of India announces an increase of the Cash Reserve Rate, what does it mean?
Explanation
The CRR is the percentage of a bank’s total deposits that it must keep as reserves with the RBI in the form of cash. This is a monetary policy tool used by the RBI to control liquidity in the economy. This amount cannot be used for lending or investment by banks. When the RBI increases the CRR, banks are required to keep a higher proportion of their deposits as reserves. This reduces the amount of money available with banks for lending to businesses and individuals.
Option (b) is incorrect: RBI does not lend money to the public or businesses. It only regulates the money supply through tools like CRR.
Option (c) is incorrect: The Union Government’s borrowing and lending activities are separate from the RBI’s monetary policy tools like CRR.
Option (d) is incorrect: An increase in CRR reduces (not increases) the amount of money available for lending by commercial banks.
