Answer :
In the excerpt from Executive Order No. 9066 by President Roosevelt, he uses the mode of persuasion known as logos, which is an appeal to the audience's sense of logic. This is because in the order, Roosevelt authorizes the Secretary of War to designate military areas and impose restrictions on individuals entering, remaining in, or leaving those areas based on military necessity or desirability. The language in the order is structured around the idea of military strategy, security, and control, appealing to the logical reasoning behind the need for such actions during wartime.
Roosevelt's use of logos in this context aims to justify the Executive Order by framing it as a strategic military decision rather than an emotional appeal or an assertion of credibility. The emphasis is on the practical and strategic aspects of the order, aligning with a logical reasoning that military actions are necessary for national security during a time of conflict.
By utilizing logos in his appeal, Roosevelt presents the Executive Order as a rational and necessary measure for the war effort, emphasizing the strategic importance of military control over certain areas and populations. This logical approach aims to convince the audience of the order's validity based on reasoned arguments rather than emotional manipulation or personal credibility.
