First, describe the situation in which someone explained to Scout what Atticus meant by saying, “It's a sin to kill a mockingbird"? Who told her
that and why? Explain specifically how Boo Radley and Tom Robinson are
like mockingbirds.

I dont know if this helps but its because they never bother anyone they only help and do they're own thing lol

The sentence that best states how the structures of the excerpts differ is:

Anaya structures his excerpt as an analysis, while Nye structures her excerpt as an observation.

Explanation:

Anaya sees in deep how the cultural elements in writing can be considered a characteristic aspect of each author and how taking them away can severely affect the emotion and intention of the writing, while Nye sees the cultural characteristics inside of an anecdote of lacking those traits or perhaps just having the feeling of the lacking of them.
