The Great Migration brought many African Americans to the Harlem Renaissance.
Explanation:
The first option would not make sense because there are lasting effects of the Harlem Renaissance such as increased civil rights for African-Americans.
The second option would not make sense because the Harlem Renaissance produced much music that we even listen to today.
The third option would not make sense because the Harlem Renaissance was a rebirth of the arts, not science.
The fourth option makes sense because the Great Migration pushed many African-Americans from the south to the north, to cities such as Harlem, where they could find new opportunities as African-Americans.
