Rice, a versatile and inexpensive source of carbohydrates, is a critical component of diet worldwide. Climate change, causing extreme weather, poses a threat to sustained availability of rice. Scientists are working on developing Green Super Rice (GSR), which is resilient under extreme weather conditions yet gives higher yields sustainably. Which one of the following is the CORRECT logical inference based on the information given in the above passage? A. GSR is an alternative to regular rice, but it can only be used in extreme weather B. GSR may be used in future in response to adverse effects of climate change C. GSR grows in an extreme weather but the quantity of produce is less than regular rice D. Regular rice will not continue to provide good yields even in extreme weather

Answer: B. GSR may be used in future in response to adverse effects of climate change

  1. Evaluate each option against the passage: A: 'GSR can only be used in extreme weather' — the passage does not say 'only in extreme weather'; this restriction is not stated. Eliminated. B: 'GSR may be used in future in response to adverse effects of climate change' — passage says scientists are working on it (future use) to address climate-change threats (adverse effects). Consistent. C: 'quantity of produce is less than regular rice' — the passage explicitly says GSR gives higher yields. Directly contradicted. Eliminated. D: 'Regular rice will not continue to provide good yields even in extreme weather' — the passage says climate change threatens availability, not that regular rice will never perform well under any condition. This overstates and introduces a claim not made. Eliminated.
  2. Confirm option B as the correct inference: The passage: scientists are working on GSR -> future use implied; to address climate-change threats -> adverse effects of climate change; GSR is resilient and high-yield -> beneficial response. Option B: 'GSR may be used in future in response to adverse effects of climate change' matches all three points exactly.
