Answer:
Scout is able to narrate historical moments and very broad social causes of American society, while Rachel narrates only from her own perspective.
Step-by-step explanation:
Although Scout and Rachel are very punctual and efficient narrators in presenting their perspectives, thoughts and emotions about the experiences and events they witnessed, they differ in a very important point. This point is the historical and social factor.
Rachel narrates only the facts that are directly related to her, while Scout narrates the facts about her, about historical events and about very broad and impacting social causes in American society. Scout has the ability to narrate prejudice, about southern society, about intolerance, about religious hypocrisy, about incorrect judgment, racism and other causes.
