With reference to the sectors of the Indian economy, consider the following pairs: Economic activity | Sector 1. Storage of agricultural produce | Secondary 2. Dairy farm | Primary 3. Mineral exploration | Tertiary 4. Weaving cloth | Secondary How many of the pairs given above are correctly matched?

Three of the four pairs are correctly matched.

1. Storage of agricultural produce — Secondary: Incorrect. Storage/warehousing is a service activity and falls under the Tertiary sector, not Secondary (which covers manufacturing and processing).

2. Dairy farm — Primary: Correct. Dairy farming is part of animal husbandry, which is a primary-sector activity (direct use of natural resources).

3. Mineral exploration — Tertiary: Correct. Exploration (surveying, prospecting, geological assessment) is a service activity carried out before extraction, and is classified under the Tertiary sector. Actual mining/extraction would be Primary.

4. Weaving cloth — Secondary: Correct. Weaving transforms raw yarn into fabric and is a manufacturing activity under the Secondary sector.

Hence, pairs 2, 3 and 4 are correctly matched — Only three.
