Answer: Roosevelt uses objective language to emphasize his authority and garner support in the execution of the order.
Step-by-step explanation:
Roosevelt doesn´t use any loaded language, such as insults or strongly emotional expressions, not to appeal to fear nor to appeal to emotions. His language is objective, centered on highlighting his authority, as well as that of the Secretary of War and the Military Commanders, and the terms of the Executive Order. His aim seems to call for support rather than present a logical argument for it. Therefore, his vocabulary should be considered as objective and aimed to emphasize his authority and get support for the execution of the order.
