Answer:
A. As a contrast to the situation in the speakers neighborhood.
Step-by-step explanation:
His neighbor resided on top of his apartment. Her notes were evidently wrong, and she shrieked. He acquired a sound system to drown and contradict her "music." He realized he missed the music he heard only after moving to a new apartment.
Ralph Ellison understood music's power. He understood that music may remind us of our history, who we were, and our goals. It is also an escape. It helps drown out life's difficulties, as he did his neighbor's terrible letters. Music not only soothes, but also resurrects and enlivens.
