Answer: The United States will never be a true democracy until everyone is a citizen
Explanation: Native Americans were forcibly removed from their ancestral lands throughout the 19th and 20th centuries. They were not heavily involved in the advances of the Industrial Revolution. Even though the Fourteenth Amendment states that all persons "born or naturalized in the United States, and subject to the jurisdiction thereof" were to be citizens, the Indian tribes were legally seen as outside US jurisdiction, thus the Amendment did not grant them citizenship. Citizenship status of Native Americans was not fully granted until the 1924 Indian Citizenship Act.
The answer is "C. The United States will never be a true democracy until everyone is a citizen."
