I would estimate that the first one is the answer.
I looked up the summary(s) for both the passages, and 'to build a fire' is about a guy who despite everything being against him, being persistent and dying because of his actions, while 'gumption' is about the hardships of african americans.

Answer and Explanation:
1. The image of people going up the hill makes me think about making progress. This is because climbing a hill is not easy and is not done quickly, on the contrary, this is a very tiring process that requires courage, strength, balance and collaboration. However, those who manage to climb the hill, it was because they provided the progress of this activity, reaching the top, which was the goal.
2. It suggests that we must overcome the political polarization we are experiencing, which promotes threats to democracy and political return instead of progress. When going up the hill, people need everyone's collaboration, because everyone has the same goal, which is to reach the top. However, polarization does not promote collaboration.
The answer would be true the phrase alone can be a sentence
