Answer: D) Personification.
Explanation: Personification is a figure of speech that consists in giving human characteristics to nonhuman objects. In the given excerpt from the poem "The First Snowfall" by James Russell Lowell we can see an example of the use of personification, in the phrase "every pine and fir and hemlock wore ermine.." it is giving the pine, fir and hemlock (nonhuman objects) a human characteristic (they are wearing ermine).
I think the answer is D, he talks about his soul never being able to get back up again, that sounds hopeless. I thought maybe B, because he talks about his hopes flying based off of someone leaving him before. But, D sounds like it fits better to me.
Either of these chances can build tension and suspense
