Which is true of both the plessy and brown cases?
both were attempts to show that segregation was unconstitutional.
both were filed by people who lived in louisiana.
both discussed whether african american children could ride in public train cars.
both were attempts to overturn the thirteenth amendment.

The answer is "Both were attempts to show that segregation was unconstitutional." Brewer took no part in the thought or choice of the case. Plessy v. Ferguson, 163 US 537 (1896) was a point of interest protected law instance of the US Supreme Court. It maintained state racial isolation laws for open offices under the teaching of "particular however equivalent".
