<span>You could say the correct answer is B.Native American Separation Act. It's goal was to separate Native-Americans from each other and to give them land individually so they could start farms or similar things.

The two possible outcomes are:
1. The boomtown losses it's economic power, and people migrate away from it to other places that they consider better for living, and thus leaving it as a ghost town.
2. After the main income of the boomtown is lost, people put their efforts into other things that can make them survive and keep the town alive, maybe a timber industry, fishing, agriculture, tourism.
