What resulted from the voluntary military service of thousands of native americans during world war i? (3 points)
many native american families moved from rural to urban areas.
native american veterans gained u. s. citizenship after the war ended.
the federal government eased its restrictions on native american land ownership.
new treaties were negotiated with native americans granting favorable conditions.

The correct answer is:

Native American veterans gained U.S. citizenship after the war ended.

More than 12,000 American Indians served in WW1, usually as scouts, snipers, and code-talkers. While a considerable number of American Indians were drafted into the war, utmost volunteered, partially in hopes that their co-operation would inspire the government to grant them full U.S. citizenship.

Thanks in part to the pressure from veterans of the Great War, most Native Americans who had not yet received U.S. citizenship acquired it under the Indian Citizenship Act of 1924.
