Answer 2

Rainsford refuses.

He hates the idea of "hunting humans." Instead, he demands to leave the island immediately. However, Zaroff tells him that that is impossible. If Rainsford refuses to participate, then he will be given to Ivan. Ivan appears to be a lot more monstruous than Zaroff. And, if Rainsford participates, he might be able to gain his freedom. Therefore, he accepts in the end.
