Explanation:

The Fifteenth Amendment prohibits denying voting rights based on race. The Voting Rights Act of 1965 eliminated discriminatory voting barriers (like literacy tests) that prevented African Americans from exercising this right. Sweatt v. Painter focused on educational segregation, the executive order desegregated the military, and Plessy v. Ferguson upheld racial segregation.
