उत्तर और व्याख्या · explanation in English
Answer: (b) केवल 1, 2 और 4
The passage names intact ecosystems such as forested catchments and wetlands, a wider pool of genetic resources, and migration corridors as aids to coping. Current crop choices, which favour homogeneity suited to past conditions, are part of the problem, not the solution.
- ✓ 1. 'Relatively intact ecosystems, such as forested catchments, mangroves, wetlands, can buffer the impacts of climate change' — these are natural water sources.
- ✓ 2. 'Accelerated breeding programmes are needed to conserve a wider pool of genetic resources'.
- ✗ 3. The existing process 'favours homogeneity adapted to past or current conditions', not varieties for warmer, wetter or drier conditions; the passage wants it changed.
- ✓ 4. Migration corridors 'may be needed to facilitate species movements to keep up with the change in climate'.
Remember · Separate what the passage recommends from what it criticises; 'existing' or 'current' practices are often the criticised part.
