Question

B. Supreme Court decision stating that public school segregation was unconstitutional

Answer 1

This refers to the landmark Supreme Court case of Brown v. Board of Education, which was decided in 1954. In this case, the Supreme Court ruled that segregation in public schools based on race was unconstitutional, overturning the previous "separate but equal" doctrine established in the Plessy v. Ferguson case. This decision paved the way for desegregation efforts in schools across the United States.
