Assistance needed.

Answer 2

C. is not the answer for the first question. It looks to me like the lynx and hare populations tend to rise and fall together.

The graph gives no reasons for the rise and decline of these populations. Nor does it indicate anything about the future. So -- that leaves only one correct answer.

What do you think these answers are now?

Answer 3

is the first one b and the second one d?

Answer 4

The first is b.

Why do you think the graph predicts the future? What do you see in the graph that indicates that both populations will decrease?
