Answer:
Oklahoma.
Step-by-step explanation:
The Indian Appropriations Act of 1889 was signed by President Grover Cleveland that allows white settlers to 'enter' into the lands of Native Indians and relocated the Indians into reservations. This Act would be the displacement of Indians away from their lands and also be kept under 'surveillance' in the reservations.
With the Act, the territory of Oklahoma was opened that led to a mad rush to the area to get their hands on lands. As the lands were cheap, and the government legally allowing the possession, the white settlers would make a dash to the land. This was the last great land rush in American history, though at the cost of the Native Indians losing their ancestral lands.
Thus, the correct answer is Oklahoma.
