Final answer:
The objective style in Frederick Douglass's narrative adds power by presenting his detachment from his childhood home in a factual manner, emphasizing the stark reality of his situation.
Step-by-step explanation:
The objective style of the excerpt from Frederick Douglass's narrative adds power to the story in that it presents Douglass's feelings about his childhood home in a detached and factual way. This lack of emotion and straightforward presentation of facts underlines the harsh reality of his experiences and the absence of traditional familial bonds. Instead of using exaggerated language or dramatization, Douglass's matter-of-fact tone underscores the disconnect he feels from what is traditionally considered a source of comfort and safety, thus enhancing the impact of his narrative on the reader.
