##### 6. Question

Read the following passages and answer the questions that follow. Your answer should be based on the passage only

Passage 1—

In high-income economies, a national minimum wage policy does raise incomes of low-wage workers, given better enforcement and governance standards. It also increases demand, with the propensity to consume higher at lower income levels. The Indian Constitution defines a ‘living wage’, and we have the Minimum Wages Act, 1948. But compliance has been weak, as abundant underemployed farm labour depresses wages.

- On the basis of above passage, following assumptions have been made:
- Low wages, constrains aggregate demand and hurt welfare of workers
- High wages can lead to unemployment since firms would be unable to pay more wages

Which of the above assumptions is/are valid?

CorrectAnswer : A

Assumption is an argument or imaginary claim that can be surely based on the claims given in the passage. The passage informs us various positive consequences of having minimum wages i.e. wages that are fair and adequate,

- It will increase income of workers—so low wages means welfare of workers is hit
- High wage means high consumption and so high demand—so low wage affects demand

Statement 1 is therefore correct

There is no mentioning of link between high wages and unemployment. While it is a normal perception, it is not given in the passage, hence it cannot be assumed. 2 is wrong.

This is not a premise based on the passage. Hence, 1 only or A is the answer.
