Answer 2

Answer:

B) culture lets the reader know which of the characters' behaviors are normal and which are unusual.

Explanation:

This is one of the ways in which understanding an author's culture can affect the way a reader interprets his or her work. In any narrative, the author will present a variety of characters that follow very particular behaviours. However, behaviours are usually normal or unusual depending on the culture we are living in. Therefore, by understanding an author's culture, we are more likely to be able to tell what the nature of the behaviour is, and what impact it will have on other characters.
