Explanation:

The Plessy v. Ferguson case centered around Homer Plessy's challenge of Louisiana's law mandating racial segregation on trains. The case established the "separate but equal" doctrine. While "separate but equal" schools became a major issue later, in this case, it was specifically about racially - segregated train cars. Poll taxes and literacy tests were other Jim - Crow era voter suppression tactics, and scare tactics were used to enforce Jim Crow laws but not the focus of this case.

Answer:

racially - segregated train cars
