Read the excerpt from an adaptation of "To Build a Fire.” The thought of it drove him on again, but he ran no more than a hundred feet before staggering and pitching headlong. It was his last panic. It occurred to him that he had been making a fool of himself, running around like a chicken with its head cut off. He was bound to freeze anyway, and he might as well take it decently and meet death with dignity. With this new-found peace of mind came the first glimmerings of drowsiness.

How does the setting create conflict in this excerpt?

The darkness of the night forces the man to desire sleep.
The extreme cold is more than the man can endure.
The loneliness of the trail makes the man lose his sanity.
