Zaroff has no conscience, while Rainsford does have a conscience.
Explanation:
In the excerpt from "The Most Dangerous Game," by Richard Connell, Rainsford is portrayed as having an inner feeling of what is right and wrong, even though he has fought in a war. Therefore, he claims that he is not a murdurer and cannot accept Zaroff's words which find murder acceptable.
The only one that makes any sense here is A. I had to read this in the sixth grade, and understood that the author implies that Zaroff is without a conscience.
It has been proven that there may be life on other planets by NASA. There is water on mars and earth. When there is water on earth and life why can't there be on mars.
