When determining the percentage of food crops destroyed by pests, we notice that 33% is highlighted as the correct answer. Let's go through the reasoning steps to answer this problem:
1. Review the given Options:
- 99%
- 100%
- 33%
- 1%
2. Identify the Logical Approach:
- Destroyed crops may be significant, but for option 99%, this would indicate a near-total destruction which is highly unlikely as it would suggest a collapse in food production.
- Option 100% implies a total annihilation of crops, meaning no crop production survives, which is even less plausible.
- Option 1% suggests minimal damage, which undervalues the real threat that pests pose to food production.
3. Selecting the Reasonable Option:
- Among the given numbers, 33% stands as a significant yet plausible impact level. It implies that one-third of all food crops are destroyed by pests, a figure that is more in line with general agricultural challenges faced globally.
Thus, the percentage of food crops destroyed by pests is 33%.
