(a) Agricultural practices that enhance biodiversity can often increase farm output and reduce the vulnerability to disasters. · (b) All the countries of the world should be encouraged to replace ecoagriculture with conventional agriculture. · (c) Ecoagriculture should be permitted in protected areas without destroying the biodiversity there. · (d) The yield of food crops will be very high if ecoagricultural practices are adopted to cultivate them.
उत्तर और व्याख्या · explanation in English
Answer: (a) जैव विविधता को बढ़ाने वाली कृषि पद्धतियाँ प्रायः फार्म उत्पादन में वृद्धि और आपदाओं के प्रति असुरक्षितता को कम करती हैं।
The examples show biodiversity-friendly farming cutting hurricane damage, raising income from pasture and coffee, improving pollination and making cattle farming more sustainable. The inference is that such practices can often raise output and reduce vulnerability to disasters.
- ✓ (a) Less hurricane damage (lower vulnerability) and higher incomes, better pollination and more sustainable cattle production (higher output) — all from practices that also add biodiversity.
- ✗ (b) The reverse of the passage, which favours ecoagriculture over conventional techniques.
- ✗ (c) The passage speaks of biodiversity outside protected areas; it does not propose ecoagriculture inside them.
- ✗ (d) 'Very high' yields is an overstatement; the passage reports reduced damage and higher incomes, not crop yields as such.
Remember · Prefer the cautious inference ('can often') that sums up all the examples over options that overstate or reverse them.
