Plessy v. Ferguson established that separate facilities are legal if equal.

• A. Supreme Court decision that separate facilities are legal if equal
• B. Desegregation occurred immediately after
• C. It overturned Brown v Board
• D. It outlawed poll taxes

Answer: (A)

The doctrine of separate but equal established by Plessy v. Ferguson held that separate facilities could be legal if they were equal in quality. This meant the Supreme Court allowed racial segregation in public spaces as long as the separated facilities were purported to be equal, effectively sanctioning Jim Crow laws for decades. The correct description mirrors this ruling: it was a Supreme Court decision stating that separate facilities are legal if they are equal. Desegregation did not happen immediately after; in fact, Plessy reinforced segregation until Brown v. Board of Education overturned it by ruling that separate educational facilities are inherently unequal. The other choices describe outcomes or issues not tied to Plessy—overturning Brown or addressing poll taxes—so they don’t fit this landmark decision.
