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

Answer: B. Only two pairs are correctly matched (rows 2 and 4). The three-sector classification: PRIMARY (extraction from nature — agriculture, mining, fishing), SECONDARY (manufacturing/processing), TERTIARY (services). (1) Storage of agricultural produce - Secondary: WRONG. Storage is a SERVICE activity, classified under TERTIARY sector, not secondary. Warehousing falls under tertiary. (2) Dairy farm - Primary: CORRECT. Dairy farming involves direct production from animals, classic primary sector activity. (3) Mineral exploration - Tertiary: WRONG. Mineral extraction is a PRIMARY sector activity. Exploration as part of mining is also primary. (4) Weaving cloth - Secondary: CORRECT. Manufacturing/processing of fibre into fabric is classic secondary sector. So 2 correct (rows 2 and 4).
