34. Which of the following was a concept established by the Plessyv. Ferguson decision? A. Separate-butequal
B. All-or-nothing
C. Just Do It
D. Make good choices.

Explanation:

In 1892, a man named Homer Plessy refused to sit in a train car designated for only black people. This eventually led to the Supreme Court cases of Plessy v. Ferguson.

This is considered a landmark court case. It decided that the "separate but equal" doctrine was constitutional. Basically, it ruled that Plessy's constitutional rules were not violated and upheld racial segregation. This ruling led to decades of discrimination, racism, and separate facilities (restaurants, water fountains, buses, etc.) for black people.

Therefore, the correct answer is A. separate but equal.
