Answer:
The central ideas about the African American experience conveyed in Langston Hughes' "I, Too" and "The Negro Speaks of Rivers" are:
A- African Americans have a proud heritage.
F- Many African Americans know too little of their cultural past.
In "I, Too," the speaker asserts his identity as an African American and declares that he, too, is an American. He also affirms his pride in his heritage and states that despite being discriminated against, he will rise above it.
In "The Negro Speaks of Rivers," the speaker traces the history of African Americans to the ancient rivers of the world. By doing so, he emphasizes the deep roots of African American culture and heritage. He also highlights the resilience and strength of African Americans in the face of oppression and slavery.
Both poems convey a sense of pride in African American identity and heritage, and emphasize the importance of understanding and celebrating this cultural legacy.
