Final answer:
The statement regarding land acquisition as a motivator in early U.S. Indian policy is true. The market revolution did bring substantive changes to the U.S., making this statement true as well. Lastly, the Three-Fifths Compromise was about representation and taxation, so that statement is also true.
Step-by-step explanation:
The question addresses various historical policies and changes affecting the United States, specifically concerning early U.S. Indian policy, the market revolution, and the Three-Fifths Compromise. Firstly, the acquisition of land was indeed a significant motivating factor in early U.S. Indian policy, as expansionist desires often led to the displacement and mistreatment of Native American tribes. Therefore, the statement is true.
Secondly, the market revolution, which occurred in the 19th century, indeed brought numerous social and economic changes to the United States, such as increased industrialization, market expansion, and a shift from agrarian to more urban-centered lifestyles. Hence, the statement is also true.
Lastly, the Three-Fifths Compromise, which was an agreement during the Constitutional Convention of 1787, indeed addressed the issue of how slaves would be counted for purposes of representation and taxation. Slaves were counted as three-fifths of a person. Accordingly, the statement is true.
Proprietary colonies like those in early America had proprietors who indeed had responsibilities beyond merely collecting profits, as they were also involved in overseeing colonial governance and maintaining relations with England. Therefore, the statement is false.
