Final answer:
The first excerpt from Wilson's speech uses pathos to evoke sympathy for the German people, while the second part uses a forceful appeal to highlight the danger of German submarine warfare.
Step-by-step explanation:
The excerpt from President Woodrow Wilson's speech, "War Message to Congress," where he discusses no quarrel with the German people and expresses sympathy, utilizes pathos, an appeal based on emotion.
He is expressing a sense of camaraderie and understanding towards the German public which is separate from the actions of their government. In the second part of the speech, Wilson describes the unrestricted German submarine warfare and its implications.
This is an appeal to force, or rather an appeal based on the audience's fear of harm, given the gravity of the action described and the potential danger it signifies for the global community.
