Sectors of the Indian Economy: Primary to Tertiary

The correct answer is A, the primary sector. Mining takes a product straight out of nature without changing its form, exactly as farming, fishing and forestry do, and every activity of that kind is placed in the primary sector.

Option B, the secondary sector, would be correct only after the ore is processed: turning iron ore into steel is manufacturing and therefore secondary. Option C, the tertiary sector, covers services such as transport, trade and banking, which produce no goods of their own. Option D, the quaternary sector, is a modern extension used for knowledge based services such as research and software, and it does not appear in the standard threefold classification that examinations use. Candidates most often place mining wrongly in the secondary sector because it is heavy industrial work, so remember the test: if the product is taken directly from nature, it is primary.

The correct answer is C, the tertiary sector. It produces no goods at all; it provides services such as transport, storage, communication, trade, banking, insurance, education, health care and administration, which is why it is commonly called the service sector.

Option A, the primary sector, is also called the agriculture and allied sector, and option B, the secondary sector, is also called the industrial sector, so all three have a second name and papers exploit the confusion. Option D, the public sector, belongs to an entirely different classification, the one based on ownership rather than on the nature of the activity; a public sector enterprise may be in any of the three sectors, as a government owned coal mine, steel plant or bank shows. Keeping the three classifications apart is the main skill this chapter tests.

The correct answer is A, agriculture. On a small family holding every member of the household may work on the land even though the work needs far fewer hands; if some of them were withdrawn, total output would not fall. Their labour is therefore adding nothing, which is what disguised or hidden unemployment means.

Option B, information technology, and option C, banking, are organised service activities where posts are sanctioned and surplus workers are not carried in this way. Option D, mining, is organised and capital intensive for the most part. The other forms of unemployment are worth learning alongside: seasonal unemployment, where work exists only in certain months, which also afflicts agriculture, and open unemployment, where a person willing to work at the going wage finds none at all. Papers ask all three definitions in rotation.

The correct answer is B, 100 days. The Mahatma Gandhi National Rural Employment Guarantee Act, passed in 2005, guarantees one hundred days of wage employment in a financial year to every rural household whose adult members volunteer to do unskilled manual work.

Options A, C and D are plausible round numbers with no basis in the Act. Two further details are asked as often as the number itself. First, the unit of the guarantee is the household, not the individual, so the hundred days are shared among the adults of one family. Second, if work is not provided within fifteen days of the demand, an unemployment allowance becomes payable by the state government. It is these enforceable claims that make the law a rights based measure rather than a welfare programme that the government may or may not run.

The correct answer is A, the primary sector. Agriculture and its allied activities still give work to the largest number of Indians, even though the sector's contribution to national income is far smaller than that share of employment would suggest.

Option C, the tertiary sector, is the strong distractor, because services do contribute the largest share of national income; but income share and employment share are two different questions, and papers set them side by side precisely to catch the candidate who has learned only one line. Option B, the secondary sector, absorbed a large part of the workforce in the countries that industrialised early, which India has not repeated on the same scale. Option D, the quaternary sector, is a later refinement covering knowledge services. The mismatch between output and employment is the reason productivity and incomes per worker in agriculture remain low.

The correct answer is C, the tertiary sector. Banking and insurance create no physical product; they support production and trade by providing credit, moving money and covering risk, and such support activities are the core of the tertiary or service sector.

Option A, the primary sector, covers activities that draw on nature directly, and option B, the secondary sector, covers the transformation of those products into manufactured goods. Option D, the unorganised sector, belongs to the other classification altogether, the one based on the conditions of employment; a bank is in fact a typical organised sector employer, with fixed hours, provident fund and job security. Note that a single word can decide the sector: growing sugarcane is primary, making sugar from it is secondary, and selling or financing that sugar is tertiary.

The correct answer is B, the conditions and terms of employment. An enterprise belongs to the organised sector when it is registered with the government and follows labour laws, so that employment is regular and secure and workers get fixed hours, paid leave, provident fund and medical benefits. Where none of this holds, the unit is in the unorganised sector.

Option A, ownership of assets, is the basis of the public and private classification. Option C, the nature of the activity, is the basis of the primary, secondary and tertiary classification. Option D has no place in any of these. The whole chapter turns on keeping the three bases apart, because an activity can be described under all three at once: a government owned steel plant is secondary by activity, organised by employment conditions and public by ownership.

The correct answer is A, ownership. In the public sector the government owns the assets and provides the services, and the aim is public welfare rather than profit; in the private sector ownership rests with individuals or companies and profit is the motive.

Option B, the number of workers, matters for definitions such as that of a factory under labour law, but not for this division. Option C, the use of machinery, distinguishes capital intensive from labour intensive production, another idea altogether. Option D, location, has no bearing on ownership. The reason the government takes up railways, roads, irrigation, power and ports is that these need heavy investment and return it slowly, so private firms would not build them at prices ordinary people could pay; they also carry benefits for the whole economy that a private balance sheet does not capture.

The correct answer is B, milk. Operation Flood, launched in 1970 and led by Verghese Kurien, linked village dairy cooperatives to city markets and made India one of the world's great milk producers. It is remembered as the White Revolution.

Option A, foodgrains, belongs to the Green Revolution, which raised wheat and rice output through high yielding varieties, irrigation and fertiliser. Option C, fish, belongs to the Blue Revolution, which promoted fisheries and aquaculture. Option D, oilseeds, belongs to the Yellow Revolution, aimed at edible oil production. These coloured revolutions are all improvements within the primary sector, and papers ask them as a matching set, so learn the four together with the two names that go with the White Revolution, Operation Flood and Verghese Kurien.

The correct answer is B. Gross domestic product is the money value of all final goods and services produced within the boundaries of a country during a year, counted sector by sector.

Option A is the classic trap, because including intermediate goods would mean double counting: the value of the flour is already inside the price of the bread, so adding both inflates the total. Option C confuses GDP with exports, which are only one part of demand. Option D describes a measure based on nationals rather than territory, which is the idea behind gross national product; the difference between the two is the net factor income earned from abroad. In India these estimates are prepared and published by the Ministry of Statistics and Programme Implementation.

The correct answer is A, running a sugar mill. A mill turns sugarcane into sugar, that is, it changes the form of a natural product, and every such transformation belongs to the secondary or industrial sector.

Option B, transporting goods by rail, option C, teaching, and option D, retail trade are all services: none of them produces a good, and each either supports production or meets a need directly, which places them in the tertiary sector. Questions of this kind are set in both directions, asking for the odd one out or for the sector of a listed activity, and the safest method is to follow the product. Growing sugarcane is primary, milling it into sugar is secondary, and carrying, storing, financing and selling that sugar is tertiary, so the same commodity passes through all three sectors.

The correct answer is B, fifteen days. The Act requires that employment be given within fifteen days of an application for work, and if the administration fails to do so, the state government becomes liable to pay an unemployment allowance to the applicant.

Options A, C and D are ordinary administrative periods offered to confuse the candidate; none of them appears in this provision. This fifteen day rule is what converts the promise into a legal entitlement, because a failure to provide work carries a cost for the government rather than simply going unmet. Along with it, remember the guarantee of one hundred days in a financial year, the household as the unit of the guarantee, the year of the Act, 2005, and the requirement that the work be unskilled manual work that the adults of the household volunteer to do.
