Question: What general principle was established with the Plessy v. Ferguson Supreme Court decision? My answer: States could not prevent African Americans from voting. Correct answer: States could require separate facilities for African Americans as long as the facilities were equal. How i know this is correct:

I know this is correct because the Plessy v. Ferguson Supreme Court decision in 1896 established the "separate but equal" doctrine, which allowed states to legally segregate public facilities based on race as long as the facilities provided for each race were considered equal. This decision upheld the constitutionality of racial segregation and set the precedent for discriminatory Jim Crow laws throughout the United States.
