Which passage from Stephen
Crane's "The Great Mistake"
contributes to the setting of
the story - the who, when,
where of the story?
A. His paper dropped unheeded.
B. The sweets of the world had laid there
in dazzling rows.
C. The babe ceased his scrutiny and again
raised his hand.

The sweets of the world had laid there  in dazzling rows.

           (who)                  (when)          (where)

the answer is:

when will (v) the books (n) be (v) due?

nouns refer to people (other than pronouns), places and things, whereas verbs describe actions and are usually part of the predicate of a sentence. finally, pronouns can work as nouns and identify the participants in speech.

in the example sentence, "will" is a verb part or auxiliary verb, "be" is an infinitive verb and "books" is a plural noun.
