Answer: B. It goes out when snow from tree branches falls on it
Explanation: In "To Build a Fire" by Jack London, what happens to the man's second fire is that it goes out when snow from tree branches falls on it. A miner is traveling the Yukon to find gold. He has to meet with other men. The protagonist is confronted with nature in a place that reaches fifty-five degrees below zero. He builds a fire under a pine tree from where he pulls its branches. This pulling makes some snow fall from the tree and puts out the fire.
