Question

What is the verb in this sentence: American literature is in many ways a series of responses to war.

Answer 1

responses?

Answer 2

it is responses

Answer 3

"is"

This is a very weak construction using the copulative (linking) verb "to be," in this case conjugated to "is."

"Much American literature responds to war." (Somewhat better construction)

Answer 4

responses is the verb

Answer 5

No. "Responses" is a plural noun.
