Greek Philosophy:
Which of the following best summarizes Plato’s Theory of Ideas?

They should be able to elect their rulers, but not govern themselves

Explanation:

the words “strangest” and “unusual” suggest that the narrator is about to tell the story of an odd or puzzling group of people.

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.
