Inference 2: Species that are widely dispersed are least likely to be extinct.

1.

Only 1 follows.

2.

Only 2 follows.

3.

Both 1 and 2 follow.

4. Neither 1 nor 2 follows.
5.

Either 1 or 2 follows.

Answer 1

Correct Answer - Option 4 : Neither 1 nor 2 follows.

Nowhere in the statement is it mentioned that gradual changes in the environment are the only reason for extinction of animal species. There are other factors like hunting and poaching. The second statement is invalid since it discusses about species that are safe from extinction.
