<span>✡ Answer: His </span><span>✡
- - Why?
This is because you need to fill in the blank with a word that makes this sentence understandable and complete.
In this case, I used a pronoun.
I'm not sure about "his" acting in the play next week.

I actually just did this as a project for my English class. Basically, they both create meaning by telling you of the struggles they went through. In "gumption" Oyster and his boy are dealing with racial injustice. In "to build a fire" he is challenged with surviving in the wilderness in the middle of winter. (hope I helped)
