The correct answer is A. all native Americans had to take up farming to keep their lands, while earlier only some of them practiced farming.
The Dawes Act was an Allotment Act that divided tribal land into allotments for individual Native Americans. Those Native Americans who agreed with the Act would be granted US citizenship. But they would be obliged to take up subsistence farming because that was the European-American model that was pushed into them so they could be assimilated into society.
They wanted to encourage Native Americans to take American habits such as thrift, industrialization and individualism, concepts that were not from their way of living.
