Answer:
Support the racial segregation under the separate but equal doctrine.
Explanation:
Homer Plessy was an African American who broke Louisiana segregation law by going in rail coach in 1896 that meant to be for "whites only". His case was taken in the U.S. Supreme Court where Plessy questioned the Separate Car Act.
After the Plessy v. Ferguson case, the Supreme Court approved the segregation of cars, which resulted in the separate but equal law throughout the South. This policy allows the segregation of African Americans possible by keeping them away from White Americans.
