Which question would most likely be answered by reading the exposition of a story? a. where was the author born? b. what kind of story is this? c. what is the main conflict? d. what is the story's theme? the correct response is b

the switch in narration increases the proximity of the narrator to the main character and the reader can perceive information only through the filter of a single character.

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.
