"The world is made up of two classes--the hunters and the huntees. Luckily, you and I are hunters." This is an example of foreshadowing because on the island Rainsford and Zaroff are the hunters and the huntees.
"Sometimes I think evil is a tangible thing--with wave lengths, just as sound and light have. An evil place can, so to speak, broadcast vibrations of evil." This quote foreshadows the evil that will be revealed when Rainsford becomes stranded on the island and finds himself to be hunted as though he is an animal. It is revealed that many men have died here as prey to Zaroff's hunting game.
"But there was one small trait of .the general's that made Rainsford uncomfortable. Whenever he looked up from his plate he found the general studying him, appraising him narrowly." This is an example of foreshadowing because it hints that there is something off about the way Zaroff is looking at Rainsford. We find out later that Zaroff is studying Rainsford as he would the game he hunts. Eventually Rainsford becomes hunted by Zaroff.
Foreshadowing is a hint at what will happen later on in the story.
