i hereby authorize and direct the secretary of war ... whenever he or any designated commander deems such action necessary or desirable, to prescribe military areas in such places and of such extent as he or the appropriate military commander may determine, from which any or all persons may be excluded, and with respect to which, the right of any person to enter, remain in, or leave shall be subject to whatever restrictions the secretary of war or the appropriate military commander may impose in his discretion.
which mode of persuasion does president roosevelt use to appeal to his audience?
an appeal based on emotion, logic, and the speaker’s credibility
pathos, an appeal to the audience’s emotions
logos, an appeal to the audience’s sense of logic
ethos, an appeal based on the speaker’s credibility

Explanation:

To determine the mode of persuasion, we analyze the text. Roosevelt invokes his authority as President and Commander - in - Chief (positions that give him credibility) to justify the executive order. Ethos is an appeal based on the speaker's credibility. The first option combines all three (ethos, pathos, logos) but the text here focuses on his authority (credibility). Pathos is about emotions, and there's no emotional appeal here. Logos is about logic, and while there's a mention of war needs, the key appeal is his credibility as President/Commander - in - Chief, which is ethos. Also, the last option defines ethos as an appeal based on the speaker’s credibility, which matches Roosevelt's use of his official position to persuade.

Answer:

ethos, an appeal based on the speaker’s credibility
