The long term significance of brown v. board of education is that it -found segregated schools to be constitutional if they were equal in quality -overturned the plessy v. ferguson ruling accepting segregates facilities -supported the case plessy v. ferguson by saying segregations was illegal -decided that each state could determine whether segregation was legal

The second one (overturned the Plessy v Ferguson ruling accepting segregated facilities) is correct

In Plessy v Ferguson the court ruled that segregation in schools was constitutional as long as the schools were equal; In Brown v The Board of Education the court's earlier decision in Plessy v Ferguson was overturned when the Warren court unanimously ruled that separate facilities were inherently unequal and that therefore segregation in schools was unconstitutional
