Final answer:
President Roosevelt appealed to his audience using the mode of ethos in Executive Order No. 9066 to establish credibility and authority for the exclusion decisions made.
Explanation:
President Roosevelt used the mode of ethos in his Executive Order No. 9066 to appeal to his audience. Ethos is an appeal based on the speaker's credibility, and in this case, by authorizing the Secretary of War to make decisions about exclusion, Roosevelt was leveraging his authority and credibility as the President.
By directing the Secretary of War to determine military areas from which people could be excluded, Roosevelt was implying that such actions were necessary for national security reasons, thus establishing his credibility and authority in making these decisions.
Utilizing the ethos mode of persuasion, Roosevelt aimed to convey to his audience that the measures taken were justifiable due to the perceived security threat posed by certain groups during wartime.
