Final answer:
Excerpt 1 from FDR's "Pearl Harbor Address to the Nation" is decisive, outlining the surprise and calculated attack by Japan, while Excerpt 2 from Senator Norris's speech is contemplative, showing Norris's caution and opposition to entering WWI.
Step-by-step explanation:
The tone between Excerpt 1 from Franklin Delano Roosevelt's "Pearl Harbor Address to the Nation" and Excerpt 2 from Senator George Norris's speech opposing America's entry into World War I is markedly different. The tone of Excerpt 1 can be described as decisive, with Roosevelt presenting a clear and unsparing account of the Japanese attack on Pearl Harbor, emphasizing the treachery and the deliberate nature of the assault. In contrast, the tone of Excerpt 2 is contemplative, as Senator Norris reflects on the implications of war, expressing his opposition and cautioning against hasty action while acknowledging the action he would take should America join the conflict nonetheless.
Roosevelt's speech conveyed a strong sense of righteousness and a call to action, underlined by the suggestion that God was on the side of the United States. In Norris's speech, there is an undertone of frustration and criticism towards both sides of the European conflict for their disregard for the rights of neutral nations, though ultimately, he expresses his commitment to support American troops should war be declared.
