Question

What happens when frog population goes down?

• A. use of pesticides increases.
• B. health of people becomes a major problem.
• C. productivity of plants decreases.
• D. the growth of plants is stunted.

Answer 1

Answer: (A)

use of pesticides increases.

Optiion A is the right answer because it is clearly mentioned at end of the passage that - 'a decline in the frog population necessitates an increase in the use of pesticides which are a serious health hazard for all living beings.

There is no evidence in the passage to suggest that Options B, C, and D are the right answers.

Hence, these are incorrect.
