With reference to the sectors of the Indian economy, consider the following pairs: 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?

Storage of agricultural produce is a service activity and belongs to the tertiary (services) sector, not secondary — pair 1 is wrong. Dairy farming involves rearing animals and producing milk, a primary sector activity — pair 2 is correct. Mineral exploration involves extraction-related activities and is classified under the primary sector, not tertiary — pair 3 is wrong. Weaving cloth is a manufacturing activity converting yarn into fabric, which is a secondary sector activity — pair 4 is correct. Hence only two pairs (2 and 4) are correctly matched.
