Robber barons were both good and bad. On the one hand, they created enormous wealth and opportunity. On the other, they drove numerous small competitors out of business, damaged the environment, and generally treated their workers very badly.
They wanted to end discrimination or decrease it. so adding in army does nothing. umm Japanese had nothing to do with that at all. they might have banned it but it didnt stop it but could have decreased it.
i think 4 is the best choice because it gave them more of an option to do things they had more rights with that.
