Answer:
Two instances of an internal conflict were when he had to assure himself to not let go and lose his nerve and his realization of the fine line between the hunter and the hunted.
And two instances of internal conflict are when he was hunted by the hounds and also when he had to get through the rough waters to get to Zaroff's bedroom and kill the man.
Explanation:
An external conflict is when the character has to get through obstacles or other characters to get to his destination. This can be in the form of man vs. nature, man, society, animals, etc. On the other hand, an internal conflict is when the character struggles within himself to get to the destination/ goal. This is also known as man vs. self.
In Richard Connell's "The Most Dangerous Game", the protagonist Sanger Rainsford faces both internal as well as external conflicts.
The internal conflicts are when he was hunted by the general. After he has had minor success in inflicting the general with some bodily harm, Rainsford decided to go for "a desperate, hopeless flight, that carried him on for some hours. Dusk came, then darkness, and still he pressed on." This flight for safety, while he’s been hunted, presents one internal conflict. Another is when he realized the small boundary between the hunter and the hunted, and the need to stay focused and not let himself be caught. A couple of times, he had to tell himself "I will not lose my nerve. I will not."
And the external conflicts are when he had to brace the forces of the forest and swimming the rough waters to get back to the General's castle. And he also had to evade the hounds seeking him out.
