The mismatch in the regional or occupational pattern of job vacancies and the pattern of worker availability results in

The correct answer is B, 1 and 2 only. The Sugamya Bharat Abhiyan is a campaign to make places, transport and information accessible; it is run by the Department of Empowerment of Persons with Disabilities and has no pension component.

Also called the Accessible India Campaign, it was launched on 3 December 2015, the International Day of Persons with Disabilities. It works on three fronts: the built environment (making government buildings, airports and stations barrier-free with ramps, lifts and accessible toilets), the transport system, and information and communication technology (accessible websites, sign language on TV). Its goal is equal opportunity and an inclusive society in which persons with disabilities can live independently.

A is wrong: statement 3 is incorrect, because disability pensions come under other schemes, not this campaign.

C is wrong: it wrongly includes statement 3 and leaves out statement 1, which is correct.

D is wrong: statement 2 is also correct, as building an inclusive society is the campaign's aim.

Exam tip: Sugamya Bharat Abhiyan, 3 Dec 2015, DEPwD; three pillars: buildings, transport, ICT.

The correct answer is C. Nominal GDP values each year's output at that year's own (current) prices, not at constant prices, so this statement is not correct.

GDP is the money value of all final goods and services produced within a country in a year. Nominal GDP uses current prices, so it can rise simply because prices have gone up. Real GDP removes this effect by valuing the output of every year at the prices of one base year, which shows the true change in production. The ratio of nominal to real GDP, multiplied by 100, gives the GDP deflator, a broad measure of inflation.

A is correct: valuing different years at common, or base-year, prices is exactly how real GDP is worked out.

B is correct: potential GDP is the output the economy could produce with full employment of labour and capital.

D is correct: real GDP divided by population gives real GDP per capita, a common measure of living standards.

Exam tip: nominal GDP = current prices; real GDP = constant (base-year) prices; deflator = nominal ÷ real × 100.

The correct answer is B, Singareni Collieries Company Limited. Incorporated in 1920 and later taken over by the government, SCCL is India's oldest government-owned coal mining company.

Coal was found in the Godavari valley near Yellandu in the 1870s, and the Hyderabad (Deccan) Company began mining there in 1886. In 1920 it became The Singareni Collieries Company Limited, a public limited company, and the Hyderabad State government bought a majority of its shares in 1945. Today the Government of Telangana holds 51% and the Government of India 49%. It mines in the Godavari valley coalfields of Telangana.

A is wrong: Neyveli Lignite Corporation was set up in 1956 to mine lignite in Tamil Nadu.

C is wrong: Coal India Limited was formed in 1975, after the coal mines were nationalised in 1971–73.

D is wrong: Mahanadi Coalfields Limited is a subsidiary of Coal India created in 1992 for the Odisha coalfields.

Exam tip: SCCL 1920 (Telangana, oldest); NLC 1956; Coal India 1975; MCL 1992.

The correct answer is C, World Economic Forum. The Global Competitiveness Report is the World Economic Forum's assessment of how well countries' institutions, policies and markets support productivity and growth.

The World Economic Forum is a Geneva-based not-for-profit foundation, set up by Klaus Schwab in 1971 and known for its annual meeting at Davos, Switzerland. Its Global Competitiveness Report, first brought out in 1979, ranks economies on a Global Competitiveness Index built on pillars such as institutions, infrastructure, macroeconomic stability, health, skills, markets and innovation. The WEF also publishes the Global Gender Gap Report and the Global Risks Report.

A is wrong: the IMF publishes the World Economic Outlook and the Global Financial Stability Report.

B is wrong: UNCTAD publishes the World Investment Report and the Trade and Development Report.

D is wrong: the World Bank published the Doing Business Report and publishes the World Development Report.

Exam tip: WEF = Global Competitiveness, Global Gender Gap and Global Risks reports; IMF = World Economic Outlook.

The correct answer is D, 1, 2 and 3. Indian bond yields respond to the RBI's policy, to domestic inflation and short-term rates, and also to the US Federal Reserve through global capital flows.

A bond's yield is the return an investor earns on it, and it moves opposite to the bond's price. When the RBI cuts the repo rate or buys government securities through open market operations, yields tend to fall; tightening pushes them up. Higher inflation makes investors demand a higher return, and short-term rates set the base from which longer yields are priced. When the US Federal Reserve raises rates, foreign investors may pull money out of Indian bonds for safer US assets, which lowers bond prices in India and lifts yields.

A is wrong because inflation and short-term rates also matter.

B is wrong because the RBI is only one of several influences.

C is wrong because both central banks also move yields.

Exam tip: bond price and yield move in opposite directions; inflation up, yields up.
