Previous Year Questions

Q1.Indian PolityAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

Consider the following statements :

1. A bill amending the Constitution requires a prior recommendation of the President of India.

2. When a Constitution Amendment Bill is presented to the President of India, it is obligatory for the President of India to give his/her assent.

3. A Constitution Amendment Bill must be passed by both the Lok Sabha and the Rajya Sabha by a special majority and there is no provision for joint sitting.

Which of the statements given above are correct ?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: B. 2 and 3 only

Explanation

The correct answer is B, 2 and 3 only. Statements 2 and 3 are correct; an amendment bill needs no prior recommendation of the President.

Under Article 368, a bill to amend the Constitution can be introduced in either House of Parliament by a minister or a private member, and the President's prior permission is not needed. Each House must pass it separately by a special majority: a majority of its total membership and two-thirds of the members present and voting. If the Houses disagree, there is no joint sitting, unlike for ordinary bills under Article 108. The 24th Amendment, 1971 made it obligatory for the President to give assent to a Constitution Amendment Bill; the President can neither withhold assent nor return it.

A is wrong: statement 1 is false.

C is wrong: statement 1 is false, and it leaves out statement 2.

D is wrong: statement 1 is false.

Exam tip: Article 368 = no prior recommendation, special majority in each House, no joint sitting, assent compulsory (24th Amendment).

Q2.Indian PolityAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

With reference to India, consider the following statements :

1. Government law officers and legal firms are recognised as advocates, but corporate lawyers and patent attorneys are excluded from recognition as advocates.

2. Bar Councils have the power to lay down the rules relating to legal education and recognition of law colleges.

Which of the statements given above is/are correct ?

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: B. 2 only

Explanation

The correct answer is B, 2 only. Only statement 2 is correct: the Bar Council of India regulates legal education and recognises law colleges.

Under the Advocates Act, 1961, only an individual enrolled on a State Bar Council's roll is an advocate. A law firm is a business entity, not a person, so it is not recognised as an advocate. A law officer of the government or a lawyer working in a company is also not treated as practising, and a full-time salaried employee cannot practise as an advocate under the Bar Council of India Rules. So statement 1 is wrong. Section 7 of the Act empowers the Bar Council of India to promote legal education, lay down its standards and recognise universities and colleges whose law degree qualifies a person for enrolment.

A is wrong: statement 1 misstates who is recognised as an advocate.

C is wrong: statement 1 is false.

D is wrong: statement 2 is correct.

Exam tip: Advocates Act, 1961 set up the Bar Council of India, which also sets the standards of legal education.

Q3.Indian PolityAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

Consider the following statements :

1. Pursuant to the report of H.N. Sanyal Committee, the Contempt of Courts Act, 1971 was passed.

2. The Constitution of India empowers the Supreme Court and the High Courts to punish for contempt of themselves.

3. The Constitution of India defines Civil Contempt and Criminal Contempt.

4. In India, the Parliament is vested with the powers to make laws on Contempt of Court.

Which of the statements given above is/are correct ?

  1. A.1 and 2 only
  2. B.1, 2 and 4
  3. C.3 and 4 only
  4. D.3 only
Show answer
Correct answer: B. 1, 2 and 4

Explanation

The correct answer is B, 1, 2 and 4. Statements 1, 2 and 4 are correct; only statement 3 is wrong.

The Contempt of Courts Act, 1971 was passed on the recommendations of the committee headed by H.N. Sanyal. Article 129 makes the Supreme Court a court of record with power to punish for contempt of itself, and Article 215 gives the High Courts the same power. The Constitution does not define civil or criminal contempt; those definitions are in Section 2 of the 1971 Act. Parliament can legislate on contempt: Entry 77 of the Union List covers contempt of the Supreme Court, and Entry 14 of the Concurrent List covers contempt of other courts.

A is wrong: it leaves out statement 4, which is also correct.

C is wrong: statement 3 is incorrect, so it cannot be part of the answer.

D is wrong: statement 3 alone is the one false statement.

Exam tip: Article 129 (SC) and Article 215 (HC) give the power; the 1971 Act (Sanyal Committee) gives the definitions.

Q4.Indian PolityAsked in: UPSC Civil Services · UPSC Civil Services Prelims 2022, 5 JuneMedium

If a particular area is brought under the Fifth Schedule of the Constitution of India, which one of the following statements best reflects the consequence of it?

  1. A.This would prevent the transfer of land of tribal people to non-tribal people.
  2. B.This would create a local self-governing body in that area.
  3. C.This would convert that area into a Union Territory.
  4. D.The State having such areas would be declared a Special Category State.
Show answer
Correct answer: A. This would prevent the transfer of land of tribal people to non-tribal people.

Explanation

The correct answer is A, prevention of transfer of tribal land to non-tribals. Paragraph 5(2) of the Fifth Schedule allows the Governor of a State to make regulations for the peace and good government of a Scheduled Area, and expressly permits regulations that prohibit or restrict the transfer of land by or among members of Scheduled Tribes. Protection of land is therefore the direct legal consequence of a Fifth Schedule declaration. B is wrong because local self-government in Scheduled Areas comes from the Provisions of the Panchayats (Extension to the Scheduled Areas) Act, 1996, and not from the declaration itself; the Schedule only sets up an advisory Tribes Advisory Council. C is wrong because a Scheduled Area remains part of the State concerned, whose executive power continues to extend to it, while a Union Territory is created by Parliament under Article 3. D is wrong because Special Category Status was an arrangement of the erstwhile National Development Council for devolution of central assistance and has no connection with the Fifth Schedule.

Q5.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

With reference to the Indian economy, consider the following statements: 1. A share of the household financial savings goes towards government borrowings. 2. Dated securities issued at market-related rates in auctions form a large component of internal debt. Which of the above statements is/are correct?

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: C. Both 1 and 2

Explanation

The correct answer is C, Both 1 and 2. Household savings reach the government through many channels, and dated securities sold in auctions make up the bulk of the Centre's internal debt.

Statement 1 is correct: households keep their financial savings in bank deposits, insurance, provident and pension funds, small savings schemes and so on. Banks, insurers and pension funds invest a large part of these funds in government securities, and small savings collections are lent to the government through the National Small Savings Fund. So a share of household savings ends up financing government borrowing.

Statement 2 is correct: dated securities are long-term government bonds with a fixed maturity, issued by the RBI on behalf of the government through auctions at market-related rates. They form the largest component of the Centre's internal debt, well ahead of treasury bills and other items.

A is wrong: it leaves out the correct statement 2.

B is wrong: it leaves out the correct statement 1.

D is wrong: both statements are correct.

Exam tip: dated securities = long-term G-secs and the main part of internal debt; treasury bills = short-term, with 91, 182 and 364 day maturities.

Q6.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

With reference to the expenditure made by an organisation or a company, which of the following statements is/are correct? 1. Acquiring new technology is capital expenditure. 2. Debt financing is considered capital expenditure, while equity financing is considered revenue expenditure. 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
Show answer
Correct answer: A. 1 only

Explanation

The correct answer is A, 1 only. Buying new technology creates a lasting asset, so it is capital expenditure; debt and equity are ways of raising money, not kinds of expenditure.

Capital expenditure is money spent to acquire or improve long-term assets such as land, buildings, machinery, patents and technology, which serve the business for many years. Revenue expenditure covers the running costs of a single period, such as wages, rent, repairs and interest. Debt financing (loans, bonds) and equity financing (issuing shares) are both sources of funds that appear on the liabilities side of the balance sheet. Either source can pay for capital or revenue spending, so calling one capital expenditure and the other revenue expenditure mixes up two different ideas.

B is wrong: statement 2 confuses sources of finance with types of expenditure.

C is wrong: it includes the false statement 2.

D is wrong: statement 1 is correct.

Exam tip: capital expenditure creates assets for years; revenue expenditure meets day-to-day costs; debt and equity are sources of funds.

Q7.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IHard

Which one of the following situations best reflects "Indirect Transfers" often talked about in media recently with reference to India?

  1. A.An Indian company investing in a foreign enterprise and paying taxes to the foreign country on the profits arising out of its investment
  2. B.A foreign company investing in India and paying taxes to the country of its base on the profits arising out of its investment
  3. C.An Indian company purchases tangible assets in a foreign country and sells such assets after their value increases and transfers the proceeds to India
  4. D.A foreign company transfers shares and such shares derive their substantial value from assets located in India
Show answer
Correct answer: D. A foreign company transfers shares and such shares derive their substantial value from assets located in India

Explanation

The correct answer is D, a foreign company transfers shares and such shares derive their substantial value from assets located in India. That is exactly what an indirect transfer means in Indian tax law.

In an indirect transfer, no Indian asset changes hands directly. Instead, shares of a foreign company are sold abroad, but those shares are valuable mainly because the company owns assets in India. The issue became famous with the Vodafone case, in which the Supreme Court held in 2012 that such a sale was not taxable in India. Parliament then amended the Income Tax Act retrospectively the same year to tax it, and the Taxation Laws (Amendment) Act, 2021 withdrew that retrospective demand for transfers made before 28 May 2012.

A is wrong: it describes ordinary taxation of an Indian company's foreign profits.

B is wrong: it describes where a foreign investor pays tax, not a transfer of shares.

C is wrong: buying and selling tangible assets abroad is a direct transaction, not an indirect transfer.

Exam tip: indirect transfer = offshore share sale deriving value from Indian assets; linked with Vodafone (2012) and the 2021 repeal of the retrospective tax.

Q8.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

Which of the following activities constitute real sector in the economy ?

1. Farmers harvesting their crops

2. Textile mills converting raw cotton into fabrics

3. A commercial bank lending money to a trading company

4. A corporate body issuing Rupee Denominated Bonds overseas

Select the correct answer using the code given below:

  1. A.1 and 2 only
  2. B.2, 3 and 4 only
  3. C.1, 3 and 4 only
  4. D.1, 2, 3 and 4
Show answer
Correct answer: A. 1 and 2 only

Explanation

The correct answer is A, 1 and 2 only. The real sector produces actual goods and services, so harvesting crops and making cloth belong to it, while lending and issuing bonds belong to the financial sector.

Economists divide an economy into the real sector and the financial sector. The real sector covers the production, distribution and consumption of goods and services: agriculture, mining, manufacturing, construction and trade. Its output is measured in physical terms and adds directly to GDP. The financial sector deals with money and claims on money, such as bank loans, shares, bonds and insurance, and its job is to move savings to those who invest in the real sector. Rupee-denominated bonds sold abroad, popularly called "masala bonds", are a financial instrument used to raise funds.

B is wrong: it includes activities 3 and 4, which are financial, and leaves out farming.

C is wrong: it includes the two financial activities and leaves out textile manufacturing.

D is wrong: bank lending and bond issues are not real-sector activities.

Exam tip: real sector = goods and services produced (farm, factory, trade); financial sector = money, credit, bonds and shares.

Q9.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IHard

With reference to the Indian economy, what are the advantages of "Inflation-Indexed Bonds (IIBs)"?

1. Government can reduce the coupon rates on its borrowing by way of IIBs.

2. IIBs provide protection to the investors from uncertainty regarding inflation.

3. The interest received as well as capital gains on IIBs are not taxable.

Which of the statements given above are correct?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: A. 1 and 2 only

Explanation

The correct answer is A, 1 and 2 only. IIBs protect investors from inflation, and because of that protection the government can borrow at a lower coupon; they carry no special tax exemption.

In an inflation-indexed bond the principal, and so the interest paid on it, is linked to a price index, so the investor's real return stays intact whatever inflation turns out to be (statement 2). Since the investor no longer needs an extra inflation premium in the coupon, the government can offer a lower coupon rate than on an ordinary bond (statement 1). The RBI issued such bonds linked to the Wholesale Price Index in 2013 and Consumer Price Index-linked bonds for retail investors later that year.

B is wrong: it includes statement 3, but interest and capital gains on IIBs are taxed under normal income tax rules.

C is wrong: it leaves out statement 2, the main purpose of IIBs, and includes the false statement 3.

D is wrong: statement 3 is false, so all three cannot be correct.

Exam tip: IIB = principal indexed to inflation, lower coupon for government, real-return safety for investor, but no tax exemption.

Q10.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

With reference to the "G20 Common Framework", consider the following statements:

1. It is an initiative endorsed by the G20 together with the Paris Club.

2. It is an initiative to support Low Income Countries with unsustainable debt.

Which of the statements given above is/are correct ?

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: C. Both 1 and 2

Explanation

The correct answer is C, Both 1 and 2. The Common Framework for Debt Treatments was agreed by the G20 and the Paris Club in November 2020 to help low-income countries with unsustainable debt.

During the COVID-19 crisis many poor countries could not service their loans. The G20 first offered the Debt Service Suspension Initiative (DSSI), which only postponed payments. The Common Framework went further: it lets eligible countries (those eligible for the DSSI) seek a full restructuring of their official bilateral debt, with all G20 creditors, including newer lenders outside the Paris Club such as China and India, negotiating together on comparable terms. The Paris Club is an informal group of major creditor countries that coordinates solutions for debtor nations.

A is wrong because statement 2, its purpose, is also correct.

B is wrong because the framework was indeed endorsed by the G20 together with the Paris Club.

D is wrong because both statements describe the framework correctly.

Exam tip: DSSI postponed debt payments; the Common Framework (2020) restructures debt of low-income countries.

Q11.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IHard

With reference to the Indian economy, consider the following statements :

1. An increase in Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee.

2. An increase in the Real Effective Exchange Rate (REER) indicates an improvement in trade competitiveness.

3. An increasing trend in domestic inflation relative to inflation in other countries is likely to cause an increasing divergence between NEER and REER.

Which of the above statements are correct ?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 1 and 3 only

Explanation

The correct answer is C, 1 and 3 only. A rise in NEER means the rupee has gained against a basket of currencies, and higher domestic inflation makes REER drift away from NEER.

NEER is a weighted average of the rupee's exchange rate against the currencies of India's trading partners; in the RBI's indices a rise means the rupee has appreciated, so statement 1 is correct. REER is NEER adjusted for the gap between Indian prices and partner-country prices. A rising REER means Indian goods are becoming dearer abroad, which hurts trade competitiveness, so statement 2 is wrong. Because REER includes relative prices and NEER does not, faster inflation in India than abroad widens the gap between the two, so statement 3 is correct.

A is wrong because statement 2 is false.

B is wrong because it drops statement 1 and keeps the false statement 2.

D is wrong because statement 2 reverses the effect of a rising REER.

Exam tip: REER = NEER adjusted for relative inflation; REER up means exports lose competitiveness.

Q12.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2022, GS Paper IMedium

"Rapid Financing Instrument" and "Rapid Credit Facility" are related to the provisions of lending by which one of the following ?

  1. A.Asian Development Bank
  2. B.International Monetary Fund
  3. C.United Nations Environment Programme Finance Initiative
  4. D.World Bank
Show answer
Correct answer: B. International Monetary Fund

Explanation

The correct answer is B, International Monetary Fund. Both are IMF windows for quick emergency financing to member countries facing an urgent balance of payments need.

The Rapid Financing Instrument (RFI) is open to all IMF members and gives fast, low-access financial help without a full-fledged programme. The Rapid Credit Facility (RCF) does the same for low-income countries but at concessional terms, through the Poverty Reduction and Growth Trust. Both were used widely during the COVID-19 pandemic, when many countries needed money quickly after sudden shocks such as natural disasters or a collapse in exports.

A is wrong: the Asian Development Bank funds development projects in Asia and the Pacific; it does not run these IMF facilities.

C is wrong: the UNEP Finance Initiative is a partnership with banks and insurers on sustainable finance, not a lender.

D is wrong: the World Bank gives long-term development loans, while short-term balance of payments support is the IMF's role.

Exam tip: RFI is for all IMF members; RCF is the concessional version for low-income countries.

Q13.Indian HistoryAsked in: UPSC Civil Services · UPSC Civil Services Exam Official 2022 PHard

In the Government of India Act 1919, the functions of Provincial Government were divided into Reserved and Transferred subjects. Which of the following were treated as Reserved subjects? 1. Administration of Justice 2. Local Self-Government 3. Land Revenue 4. Police. Select the correct answer using the code given below:

  1. A.1, 2 and 3
  2. B.2, 3 and 4
  3. C.1, 3 and 4
  4. D.1, 2 and 4
Show answer
Correct answer: C. 1, 3 and 4

Explanation

The correct answer is C, 1, 3 and 4. Under dyarchy the Governor kept the reserved subjects, which were those touching revenue and coercive power: administration of justice, land revenue, police, irrigation, famine relief, forests and labour relations. Local self-government, along with education, public health, agriculture, industries and excise, belonged to the transferred list, run by Indian ministers answerable to the legislative council. Option A is wrong because it includes local self-government, a transferred subject. Option B is wrong for the same reason, as it too carries local self-government. Option D is wrong because it drops land revenue, the most jealously guarded of the reserved subjects, and adds local self-government. The simple rule for the examination hall is that whatever earned money or kept order was reserved, and whatever spent money on people was transferred.

Q14.Art & CultureAsked in: UPSC Civil Services · UPSC Civil Services Exam Official 2022 PHard

With reference to Indian history, consider the following pairs: Historical person - Known as 1. Aryadeva - Jaina scholar 2. Dignaga - Buddhist scholar 3. Nathamuni - Vaishnava scholar How many pairs given above are correctly matched?

  1. A.None of the pairs
  2. B.Only one pair
  3. C.Only two pairs
  4. D.All three pairs
Show answer
Correct answer: C. Only two pairs

Explanation

The correct answer is C, only two pairs. Dignaga and Nathamuni are matched rightly while Aryadeva is not, so exactly two pairs are correct. Aryadeva, who lived about the third century, was a Buddhist monk of the Madhyamaka school and the chief disciple of Nagarjuna; his Chatuhshataka defends the doctrine of emptiness, so calling him a Jaina scholar is wrong. Dignaga, of the fifth or sixth century, founded the Buddhist school of logic and wrote the Pramanasamuchchaya, which shaped debate on perception and inference for centuries. Nathamuni, of about the tenth century, was the first acharya of the Srivaishnava tradition at Srirangam; he gathered the Tamil hymns of the Alvars into the Nalayira Divya Prabandham and was the grandfather in the line that led to Ramanuja. A is wrong because two pairs do match. B understates the count and D overstates it. Exam tip: Nagarjuna, Aryadeva, Buddhapalita and Chandrakirti all belong to the Madhyamaka line.

Q15.Indian EconomyAsked in: UPSC Civil Services · UPSC Civil Services Prelims 2022Hard

Consider the following statements: 1. Tight monetary policy of US Federal Reserve could lead to capital flight. 2. Capital flight may increase the interest cost of firms with existing External Commercial Borrowings (ECBs). 3. Devaluation of domestic currency decreases the currency risk associated with ECBs. Which of the statements given above are correct?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: A. 1 and 2 only

Explanation

The correct answer is A, 1 and 2 only. Statement 1 is right because when the United States Federal Reserve tightens, returns there become attractive and portfolio money flows out of emerging markets, which is capital flight. Statement 2 is right because such an outflow weakens the rupee and raises risk premiums, so a firm servicing an external commercial borrowing pays more in rupee terms and finds refinancing dearer. Statement 3 is wrong, and this settles the other options: a fall in the value of the domestic currency raises, not lowers, the currency risk on a loan that must be repaid in dollars, because every dollar of repayment now costs more rupees. Option B is wrong because it accepts the faulty third statement and drops the correct first one, option C is wrong for accepting statement 3 while leaving out statement 2, and option D is wrong because it accepts all three.

Q16.Indian EconomyAsked in: UPSC Civil Services · UPSC Civil Services Prelims 2022Hard

With reference to the Indian economy, consider the following statements: 1. An increase in the Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee. 2. An increase in the Real Effective Exchange Rate (REER) indicates an improvement in trade competitiveness. 3. An increasing trend in domestic inflation relative to inflation in other countries is likely to cause an increasing divergence between NEER and REER. Which of the above statements are correct?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 1 and 3 only

Explanation

The correct answer is C, 1 and 3 only. Statement 1 is right because the NEER is a trade weighted index of the rupee against a basket of partner currencies, so a rise in the index means the rupee has appreciated in nominal terms. Statement 3 is right because the REER adjusts the NEER for relative prices, so when domestic inflation runs faster than inflation abroad the two indices move apart. Statement 2 is wrong, and this is why options A, B and D fail: a rise in the REER means the rupee has become expensive in real terms, which makes Indian goods dearer abroad and weakens, not improves, trade competitiveness. Option A is wrong because it accepts statement 2 and leaves out the correct statement 3, option B is wrong because it accepts statement 2 and drops the correct statement 1, and option D is wrong because it accepts all three including the faulty second one.

Q17.Environment & EcologyAsked in: UPSC Civil Services · Prelims GS Paper I, 5 June 2022Hard

Which one of the following statements best describes the 'Polar Code'?

  1. A.It is the international code of safety for ships operating in polar waters.
  2. B.It is the agreement of the countries around the North Pole regarding the demarcation of their territories in the polar region.
  3. C.It is a set of norms to be followed by the countries whose scientists undertake research studies in the North Pole and South Pole.
  4. D.It is a trade and security agreement of the member countries of the Arctic Council.
Show answer
Correct answer: A. It is the international code of safety for ships operating in polar waters.

Explanation

The correct answer is A. The Polar Code is the International Code for Ships Operating in Polar Waters, adopted by the International Maritime Organization and in force since the beginning of 2017. It is mandatory under the conventions on safety of life at sea and on prevention of pollution from ships, and it covers ship design, equipment, crew training and operation in ice-covered waters, as well as discharges of oil, sewage and garbage in the Arctic and the Antarctic.

Option B is wrong because territorial claims in the Arctic are dealt with under the law of the sea and the continental shelf procedure, not by this code. Option C describes what the Antarctic Treaty system and its environmental protocol do for scientific activity. Option D is wrong because the Arctic Council is a forum for cooperation on environment and sustainable development and does not conclude trade or security agreements.

Q18.General ScienceAsked in: UPSC Civil Services · Prelims GS Paper I, 5 Jun 2022Easy

Which one of the following is the context in which the term 'qubit' is mentioned?

  1. A.Cloud Services
  2. B.Quantum Computing
  3. C.Visible Light Communication Technologies
  4. D.Wireless Communication Technologies
Show answer
Correct answer: B. Quantum Computing

Explanation

The correct answer is B, Quantum Computing. A qubit, short for quantum bit, is the basic unit of information in a quantum computer. An ordinary bit can be only 0 or 1, but a qubit can exist in a superposition of 0 and 1 at the same time, and qubits can be entangled, so that the state of one is linked to another. Because of this, a set of qubits can explore many possibilities together, which could let quantum computers solve certain problems, such as simulating molecules or breaking some kinds of encryption, far faster than classical machines. Qubits are built from superconducting circuits, trapped ions or photons, and most must be kept close to absolute zero. India supports this field through its National Quantum Mission, approved in 2023. Option A is wrong because cloud services run on ordinary bits and servers. Option C is wrong because visible light communication, or Li-Fi, sends data using LED light. Option D is wrong because wireless communication uses radio waves, not qubits. Exam tip: a bit is 0 or 1, a qubit means superposition and entanglement.

Q19.Indian EconomyAsked in: UPSC Civil Services · Prelims GS Paper I, 5 Jun 2022Hard

With reference to the Indian economy, consider the following statements:

1. If the inflation is too high, Reserve Bank of India (RBI) is likely to buy government securities.

2. If the rupee is rapidly depreciating, RBI is likely to sell dollars in the market.

3. If interest rates in the USA or European Union were to fall, that is likely to induce RBI to buy dollars.

Which of the statements given above are correct?

  1. A.1 and 2 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: B. 2 and 3 only

Explanation

The correct answer is B, 2 and 3 only. Selling dollars supports a falling rupee and buying dollars absorbs heavy inflows, but to fight inflation the RBI sells, not buys, securities. Buying government securities through open market operations pumps rupees into the system and would add to inflation, so when inflation is too high the RBI sells securities to soak up money. So statement 1 is wrong. When the rupee is falling fast, the RBI sells dollars from its reserves, which raises the supply of dollars and steadies the rupee, so statement 2 is right. When interest rates in the USA or the EU fall, investors move money to India for better returns; the dollar inflow pushes the rupee up, and the RBI buys dollars to prevent sharp appreciation and to add to reserves, so statement 3 is right. Option A is wrong because it includes statement 1. Option C is wrong for the same reason. Option D is wrong because statement 1 is false. Exam tip: high inflation, sell bonds; weak rupee, sell dollars; heavy inflows, buy dollars.

Q20.GeographyAsked in: UPSC Civil Services · Prelims GS Paper I, 5 Jun 2022Easy

In the northern hemisphere, the longest day of the year normally occurs in the:

  1. A.First half of the month of June
  2. B.Second half of the month of June
  3. C.First half of the month of July
  4. D.Second half of the month of July
Show answer
Correct answer: B. Second half of the month of June

Explanation

The correct answer is B, Second half of the month of June. The longest day in the northern hemisphere is the summer solstice, which falls on 20, 21 or 22 June, usually 21 June. On that day the Sun is overhead at the Tropic of Cancer (23.5° N), because the North Pole is tilted most towards the Sun. Places north of the equator get their longest daylight and shortest night, and north of the Arctic Circle the Sun stays above the horizon for 24 hours.
