Final answer:
Du Bois uses repetition and duality to highlight the internal conflict of double-consciousness among African Americans.
Explanation:
Du Bois's use of repetition and duality reinforces his experiences with "double-consciousness" by emphasizing the internal conflict and struggle he faces as an African American in American society. Through the repetition of contrasts between being an American and a Negro, he illustrates the dual identity and the constant battle between two opposing ideals within himself.
This repetition conveys the complex reality of living with multiple layers of consciousness and the challenges of reconciling conflicting aspects of one's identity, contributing to the profound theme of double-consciousness in Du Bois's work.
