When did you memorize the patriotic poem, "Paul Reveres ride"?

Question

In the above sentence is the predicate
did memorize? If so what part of the sentence would the word poem be??

Answer 1

Yes, "did memorize" is the main verb or predicate. The basics of this sentence are as follows:

you ... did memorize ... poem

What do you think the word "poem" is doing in this sentence if "you" is the subject and "did memorize" is the verb?
