Answer:
Harsh weather.
Little experience.
Deep snow.
Steep trails.
No communication.
Step-by-step explanation:
Jack London's short story "To Build A Fire" revolves around the story of an unnamed protagonist who had gone to the Yukon to get to his friends at Henderson Creek. His journey to the camp was met with numerous obstacles that in the end proved fatal for him.
The difficulties providing challenges to the young man and his dog were harsh weather and deep snow. It was snowing continuously, with the snow coming as deep as three or more feet. He also has little to no experience in the area, for "He was a newcomer in the land, and this was his first winter." Moreover, the steep trails and the unavailability of easy communication further put him in conflict with the forces of nature. In the end, he ended up dead, with just the dog reaching the destination.
Thus, the correct answers are all the options except "dirty hotels".
