Taylor is writing a literary analysis of "To Build a Fire" and its connection to historical events. Which is the best example of a clear topic sentence for her analysis?

In To Build a Fire in Jack London's 1908 story of life in the winter in the Yukon the author talks about the extreme dangers of hiking alone at - 59 degrees centigrade and the difficulty of lighting a fire to warm up. Historically, it would be about just after the gold rush of 1898 in the Yukon in which many ill-prepared men came from warmer climes (like Sam McGee of Plumtree Tennessee) and perished due to lack of respect for the harsh winter conditions.
