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?

1. Storage of agricultural produce — Secondary: Correct. In standard sectoral classification used in Indian economy questions, activities that add utility after production such as processing, preservation and storage are often grouped with the secondary sector.

2. Dairy farm — Primary: Correct. Dairy farming is an animal husbandry activity based on direct use of natural resources, so it belongs to the primary sector.

3. Mineral exploration — Tertiary: Incorrect. Exploration of minerals is linked to the primary sector because it concerns discovery/extraction of natural resources, not services.

4. Weaving cloth — Secondary: Correct. Weaving converts raw material/yarn into cloth, so it is a manufacturing activity in the secondary sector.

Hence, three pairs are correctly matched.
