Read this question in English
Which among the following is the most logical and critical inference that can be made from the above passage?
(a) In our agricultural practices, we have become heavily dependent on expensive chemical fertilizers and toxic pesticides only due to green revolution · (b) Monocropping vast fields with high-yield varieties is possible due to green revolution · (c) Monocropping with high-yield varieties is the only way to ensure food security to millions · (d) Green revolution can pose a threat to biodiversity in food supply and food security in the long run
उत्तर और व्याख्या · explanation in English
Answer: (d) हरित क्रांति, दीर्घ काल में खाद्य-पूर्ति और खाद्य सुरक्षा में जैव-विविधता के लिए खतरा प्रस्तुत कर सकती है
The passage calls the green revolution a mixed blessing: reliance on uniform high-yield crops has caused a 'dangerous dwindling of biodiversity' in our food and has put us 'at risk for food shortages in future'. So it can threaten both biodiversity and long-run food security.
- ✗ (a) 'Only due to green revolution' is too extreme; the passage links chemicals to high-yield varieties, not as the sole cause of dependence.
- ✗ (b) A plain factual link that leaves out the risk the passage is warning about.
- ✗ (c) 'The only way' runs against the passage, which says this practice risks future food shortages.
- ✓ (d) 'Dangerous dwindling of biodiversity in our food supply' and 'at risk for food shortages in future'.
Remember · A 'critical inference' carries the author's warning; drop options with 'only' and neutral facts that miss the author's concern.
