The POV is third person and the setting is Ship-Trap Island.
An example of foreshadowing is when Whitney is talking about Ship-Trap Island. This is foreshadowing because the name suggests that something might happen to the yacht that Whitney and Rainsford are on or that something might happen to someone on the yacht.
Swam. I found it quicker than walking through the jungle.
Rainsford! How in God's name did you get here?!
I congratulate you. You have won the game.
The conflict is when Rainsford realizes that General Zaroff hunts men, not animals. That is an example of man vs. man conflict.
The climax is when Rainsford jumps into the ocean to escape General Zaroff and his dogs. This is the climax because when he jumps into the water, the reader doesn't know if he is still alive or not.
An example of irony is when Rainsford is in General Zaroff's room. That is an example of situational irony.
The central theme is murder because General Zaroff murders people for fun.
