Question

the plessy v ferguson ruling stated that
○ segregation was unconstitutional.
○ the fourteenth amendment was unconstitutional
○ segregation was necessary to preserve public peace.
○ the separate car act was unconstitutional.

Explanation:

In the Plessy v. Ferguson case, the Supreme Court ruled that racial segregation laws (like the Separate Car Act) were constitutional under the "separate but equal" doctrine, and part of the reasoning related to maintaining public peace through segregation. The other options are incorrect: segregation was ruled constitutional (so first option is wrong), the Fourteenth Amendment wasn't ruled unconstitutional (second option wrong), and the Separate Car Act was ruled constitutional (fourth option wrong).

Answer:

C. segregation was necessary to preserve public peace (Note: Assuming the options are labeled A, B, C, D with the third option as C. If original labeling differs, adjust the identifier but keep the text. The key is the content "segregation was necessary to preserve public peace" as the correct description of the ruling's reasoning related to the options given.)
