The bond between family members is apparent in this excerpt from Across Five Aprils. How does using third person limited omniscient point of view help reveal this bond?

Using third person limited omniscient point of view, the narrator was able to tell what she thought, felt, had read, or been told about the family bond.  She does not claim to know all the thoughts and feelings of the family members regarding the bond.

So, the author of "Across Five Aprils" relied heavily on her research about the civil war and what her grandfather told her about the Creighton family and their participation in the civil war.

Explanation:

1. "Across Five Aprils" is a 1964 novel by Irene Hunt set around the Civil War era.  Through Jethro, the main protagonist, Hunt used him as a vehicle to narrate what a family passes through during times of upheaval, like wars.

2. The third-person point of view narrates a story about the actions of the characters using third-person pronouns such as "he," "she," and "they." It's one of the most common perspectives in works of fiction.

3. There are two types of third-person point of view.  Using omniscient third-person point of view, the narrator depicts that she knows all of the thoughts and feelings of all of the characters in the story.  She is a close observer of events surrounding the characters.  On the other hand, using limited third-person point of view, the narrator relates only her own thoughts, feelings, and knowledge about various situations and the other characters.  Here, the writer or narrator is a distant observer.

so is this a rhetorical question?
