Answer:
A. character versus nature
Explanation:
It is not B character versus society because "society" is the broad term for the world of people in general. For example, a society could be just how things work, like in the <em>Hunger Games</em> where people are forced to fight to death every year. This story is not versus society because there is no group of people deciding how things work. We rule out B.
The only character in this story is Mike. So, we can rule out C, character versus character. Character versus character means two characters facing off and fighting each other.
It is not D character versus self because Mike isn't his own enemy. He knows how to act on his own and to do the best thing for himself to survive. SO, we rule out D.
Now, the only answer left is A: character versus nature. We have the character, Mike, and we have the conflict: nature. What are the things that are causing Mike problems in the story? The setting sun is about to make everything pitch dark which will make it hard for Mike to see. Mike is stuck on one side of a river. He would be lost if he went on an unfamiliar track. These are all nature conflicts.
The answer is A character versus nature.
