उत्तर और व्याख्या · explanation in English
Answer: (c) केवल 2 और 3
Arhar straw is green, decomposes fast and can be ploughed back, while silica-rich paddy straw is hard to break down and so gets burnt. Two inferences follow: growing this pulse avoids the burning that pollutes (2), and its straw can enrich the soil (3).
- ✗ 1. The yield is compared with 'existing varieties' of arhar, not with paddy; nothing is said about income.
- ✓ 2. Paddy stalks are burnt because they cannot be ploughed back, while arhar straw is ploughed in — so the pulse crop avoids the smoke from stubble burning.
- ✓ 3. Arhar straw 'can be ploughed back into the soil' and 'will decompose very fast', returning organic matter to the soil.
- ✗ 4. The passage says paddy straw is hard to decompose or salvage, not that it has 'no usefulness' at all.
- ✗ 5. Arhar is also combine-harvested yet its straw is not burnt; the cause is paddy straw's 'high silica content'.
Remember · Reject inferences that compare things the passage never compares (income) or use extreme words ('no usefulness', 'main cause').
