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.
