The social background of the character or author in a piece of literature is a part of his or her: a. rhetoric. b. culture. c. medium. d. genre

B. culture

Explanation:

Medium is an agency or means of doing something. Literature, a medium is the physical structure in which the work is passed along.

Rhetoric is a bunch of techniques which one can use to convince the others of his or her point of view.

Genre is basically a category.

In the end, we have culture, which can be defined as: "the customs, arts, social institutions, and achievements of a particular nation, people, or other social group."

i say that the right answer is: three personal subject pronouns. that’s because you will see “she” two times, referring to the librarian, and “they” one time, referring to the books. personal subject pronouns are used to replace common nouns or proper names.

the only possessive noun it’s present on the first sentence, when the speaker refers to “his” father.
