Answer: I cant remember off the top of my head but I am pretty sure the correct answer is C) allowed federal government to raise money by selling land.
Explanation: This is because the government needed money to hire people to work for them. So they would "take" the free land and sell it to incoming colonists for profit.
The saying "resource rich, labor poor" is big during this time. This is why colonists moved to America, the resources. Of course no one wanted to do the work to obtain such resources which is what lead to selling land in the first place. Sell the land, hire people to do the tough labor, make profit.
