Question

by signing executive order no. 9066, president roosevelt assumed that
○ no one would actually be interned in camps.
○ he was doing what was best for his nation.
○ his direction and command would end the war.
○ the internment camps would be permanent.

Explanation:

Executive Order No. 9066 led to the internment of Japanese Americans during WWII. Roosevelt's action was framed as a national security measure, so he likely believed he was acting in the nation's best interest. The other options are inconsistent: internment camps were used (so first is wrong), the order didn't aim to end the war directly (third is wrong), and there's no indication camps were meant to be permanent (fourth is wrong).

Answer:

B. he was doing what was best for his nation.
