I think it means how dreams can take up a lot of space in your mind which means you will be determined to work hard on that dream.

I believe the correct answer is <span>Zaroff has no conscience, while Rainsford does have a conscience.
As you can see in the excerpt, Zaroff is not opposed to murdering other people, which he considers to be just a type of hunting. He doesn't value human life at all, and is indifferent towards whether they live or die, which is why his character is different from that of Rainsford's.
