Final answer:
The historic standards of beauty played a significant role in the Supreme Court's decision to reverse segregation.
Step-by-step explanation:
The question is about how historic standards of beauty factored into the U.S. Supreme Court's decision to reverse the Plessy v. Ferguson decision. In the Brown v. Topeka Board of Education case, NAACP lawyers used an experiment where young Black girls were asked to choose between Black and White dolls as evidence of racial discrimination. The dolls' choices revealed the impact of societal standards of beauty on the treatment of Black children. This experiment helped to highlight the negative implications of segregation and led to the landmark Supreme Court decision.
