Question

Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]. Assertion [a]: One of the best ways to reduce the amount of solid wastes is to reduce the consumption of raw materials. Reason [r]: Solid wastes are seldom generated when raw materials are converted to goods for consumption.

Correct answer (D) [a] is true but [r] is false Solution Assertion [a] is true. Source reduction, which includes reducing the consumption of raw materials, is considered the most effective strategy in the waste management hierarchy to minimize solid waste generation. Reason [r] is false. The conversion of raw materials into finished goods (manufacturing and processing) is a major source of industrial solid waste. It is incorrect to say that waste is 'seldom' generated during this process. Therefore, [a] is true but [r] is false. Turn this into a strength.
