Question

during world war ii, native americans
served in the military and worked in war production.
prospered, especially those on reservations.
became more isolated within american society.
collaborated with the japanese.
were eligible for gi bill benefits only if living on reservations.

Explanation:

During WWII, Native Americans actively contributed to the war effort: thousands served in the U.S. military (notably including code talkers), and many others took jobs in domestic war production facilities. The other options are incorrect: those on reservations generally did not prosper due to ongoing systemic inequities, the war actually reduced their isolation through military and work integration, there was no widespread collaboration with Japan, and GI Bill eligibility was not restricted to reservation residents.

Answer:

served in the military and worked in war production.
