In this straightforwardly iambic line, Richard extends the metaphor by comparing the erstwhile reign of Lancaster to the gloom of a cloudy sky, playing upon the "sun of York" line that precedes it. Lour'd—Shakespeare uses the apostrophe to signal that "loured" should absolutely not be pronounced as "louréd"—is an archaism (from the Middle English louren; probably deriving from Middle High German luren "to lie in wait") that meant "to look sullen; to frown upon." The reference to "our house" refers primarily to the family of York, although it could also play off one of its meanings as "the management of domestic affairs" (referring to the War of the Roses).
The following are elements of Sartre's existentialist philosophy:
B. Humans endure life alone, without God. He believes that God does not exist and man can exist without God.
C. Life is meaningless and fundamentally absurd. He believes that life has no meaning, life is by chance, we are born by chance and death is by chance, we die by chance. There is no God.
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.
Of course, this is just my estimation.
