How does Amanda Gorman marry sound to sense, her language to her message, in these lines? We’ve seen a force that would shatter our nation rather than share it,
Would destroy our country if it meant delaying democracy.
And this effort very nearly succeeded.
But while democracy can be periodically delayed,
It can never be permanently defeated.
In this truth, in this faith, we trust.

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.

i believe it is the first choice (1.)

because the major theme is(“both the wild and civilization have rules.”)

and also as u said,( based on what buck learns within the call of the wild, "both the wild and civilization have rules".this is true of humans within society as well.
