Question

which of the following was not a reason for the japanese relocation during world war II
A) Americans had a widespread fear of further attacks following Pearl Harbor.
B) Other Americans questioned Japanese Americans' patriotism.
C) Japanese Americans were proven to be assisting the enemy with radio messages.
D) Americans believed Japanese Americans would be more loyal to Japan than to the United States

Answer 1

The correct answer is C. Japanese Americans were proven to be assisting the enemy with radio messages. 
This actually never happened - and even if Japanese Americans did assist Japan via radio messages, that was definitely never proven. The other three options show the sentiment of the time, and that is that Americans didn't trust Japanese Americans at all.
