What does the repetition of the word "neutral" throughout "How We Entered World War I" emphasize?

Repeating the word “neutral” emphasizes the United States’ position before it entered the war: it tried to stay out of the conflict and avoid taking sides. This matches choice B, the stance taken by the United States in its attempt to remain isolated from World War I.
