The "umbrella statement" for all parts of an argument in a speech is called the claim.
Here's why:
1. A claim is the main point or central argument that a speaker is trying to make in a speech. It is the overarching idea that all other parts of the argument support.
2. A claim is usually presented early in the speech to give the audience a clear understanding of the speaker's position.
3. Think of the claim as the thesis statement of the speech. It guides the direction of the argument and sets the tone for the rest of the presentation.
4. Without a clear and strong claim, the speech may lack focus and coherence, making it harder for the audience to follow the speaker's logic.
Therefore, in the context of an argument in a speech, the umbrella statement that ties all parts together is the claim.
