Answer:
I don't know what your answer choices are, but here is some information.
The case was about a man named Homer Plessy, the account takes place in 1892. Homer sat in a train car reserved for whites, and after refusing to move he was arrested and jailed. The court ruled that the "separate but equal" doctrine was not unconstitutional, and that the train car designated to the "colored" was not inferior. After this case many more locations followed the Jim Crow laws (That's why there were so many signs for "whites only" and "no colored") It was not until the Brown v. The Board of Education case in 1954 that this issue was addressed by the supreme court, they ruled that segregation because of race in schools was unconstitutional. Hope this helps you some :)
