The question is incomplete, and the full version can be found on quizlet.
Answer: d. The Brown case addresses whether facilities separated by race are permissible by law.
Step-by-step explanation:
The question provides a recount of the Supreme Court's ruling in Plessy v. Ferguson (1896) and requires one to choose which is the best way to explain the relationship between that case and Brown v. Board of education (1954) from the provided options.
Only option D correctly establishes a relationship by stating that both cases are about whether or not facilities separated by race are permissible by law.
While Plessy v. Ferguson had a petitioner complaining about being forced to seat in a train coach assigned by the train company for people not of the white race, Brown v. Board of education ruled that racial segregation in public schools was unconstitutional.
