On the basis of the above passage, the following assumptions have been made:
1. Humans have been the main reason for the large scale extinction of plant species.
2. Consumption of food mainly from locally cultivated crops ensures crop diversity.
3. The present style of production and distribution of food will finally lead to the problem of food scarcity in the near future.
4. Our food security may depend on our ability to preserve the locally cultivated varieties of crops.
Which of the above assumptions are valid?
(a) 1 and 3 · (b) 2 and 4 · (c) 2 and 3 · (d) 1 and 4
उत्तर और व्याख्या · explanation in English
Answer: (b) 2 और 4
Varieties bred to suit local conditions have given way to a few high-yielding varieties and technology-driven production and distribution, and we may need the lost varieties if disease or climate change strikes. So food security may depend on preserving local varieties, and eating from locally grown crops keeps that diversity alive.
- ✗ 1. The passage is about varieties within a few crops, not the extinction of plant species at large.
- ✓ 2. Diversity came from crops suited to 'their local climate and environment' and is being lost to a few varieties spread by technology-driven distribution; relying on local crops is what sustained it. 'Ensures' is strongly worded, but it follows the passage's contrast.
- ✗ 3. The passage says 'if' disease or climate change strikes, 'we might' need the varieties — a risk, not a certain scarcity in the near future.
- ✓ 4. 'We might desperately need some of those varieties' — food security may depend on keeping them.
Remember · 'If … might' in a passage supports 'may', never 'will finally lead to'; and crop varieties are not plant species.
