Answer:
Plessy v. Ferguson was a landmark 1896 U.S. Supreme Court decision that upheld the constitutionality of racial segregation under the “separate but equal” doctrine. The case stemmed from an 1892 incident in which African American train passenger Homer Plessy refused to sit in a car for blacks. Rejecting Plessy’s argument that his constitutional rights were violated, the Supreme Court ruled that a law that “implies merely a legal distinction” between whites and blacks was not unconstitutional. As a result, restrictive Jim Crow legislation and separate public accommodations based on race became commonplace.

The Japanese businessmen prefer to feel having a mutual respect and trust with the person they are going to negotiate with. They also prefer meeting up multiple times before negotiating and they don't make rash decisions instead they prefer to take their time in making any important decisions. Japanese businesspersons do not negotiate in an Arab manner. They will always maintain their politeness and their face should look focused on such negotiation. They are reluctant to say no and will not make a negative reply when they don't want to accept you for being their partner.
I believe when you say suffrage you are referring to the right to vote, so that means that the aristocrats had less power than before. Hope this helps :)
