It depends on what type of essay you are writing . If it’s argumentative it also depends on if you are writing it for the intro. The intro goes:
Hook- catch attention
Thesis- restate argument
Claim- what you think
Answer:
The strange thing about Zaroff's reply is that he thinks that Rainsford is sickened by his long swim before he arrived, however, we know that he is sickened by the thought of Zaroff's library of heads he has mounted and the idea of the "game" he has created.
Explanation:
Before Rainsford excuses himself, Zaroff invites Rainsford to view his collection of heads of men that he has hunted. When Rainsford claims that he is not feeling well, Zaroff's thinks that he is tired from the swim when in reality, he is sickened by Zaroff's horrifying "game" he has created. The point is: it does not enter Zaroff's mind that Rainsford might be sickened at Zaroff's custom of hunting humans.
