Which literary device is used in these lines from the first stanza: beneath a skin, the city stretches, each street pulses? in the poem Night Flight?

Personification.

Explanation:

"each street pulses." and "beneath a skin" suggest the street has a pulse beneath a skin, which we know is not something a street has, but humans do. Personification is when a non-human thing is describes to have the characteristics or aspects that humans have. Which is exactly what the poem is doing, leaving us with the conclusion that the literary device used is Personification.

explanation:

you only need simple sentences to answer this. just answer these questions.

what do you think annie thinks of the mother? do you think annie believes the mother is a fit mother for helen.

what about the father? what would annie think of him? she might not like him, but does she respect him.

how about the son? would annie think he is the only voice of sanity in an insane place?

what about helen herself? this is the key question. how does she see helen? what do you suppose she thought her first job was going to be.

these aren't hard questions. just state the obvious. annie is not that well educated: she just knows what she has to do. write it that way.

you can do it if you've read the book or seen the play or movie.
