When it is seventy-five below zero, a man must not fail in his first attempt to build a fire.

Explanation:

This is the statement that best hints at the fact that there is a hidden danger along the actual Yukon trail. In this passage, the man tells us of how his dog resisted the cold. He also mentions that building a fire is extremely important, and he says that "a man must not fail in his first attempt to build a fire." The implication here is that failing to build a fire would most likely have terrible consequences for the person.

the answer is "a" although apex might say best book of the year.
