What best defines the thesis of a speech?

• A. A statement defining or expressing the purpose of the speech.
• B. A word or phrase in a speech that connects one part to the next.
• C. An audience that is neutral or hasn't made up their minds about the speaker's topic.
• D. Presentation of evidence by such visual means as charts, graphs, photographs, and physical objects.

Answer: (A)

The thesis is the central statement that expresses the purpose and main claim of the speech. It serves as the one clear sentence that tells the audience what you intend to prove, explain, or persuade them to accept. Because of that, it provides direction for the entire talk: every point you cover should relate back to that core idea, and the structure of the speech will be built around supporting it.

This is why the thesis is distinct from other elements. A transition word or phrase that links sections helps move from one idea to the next, but it isn’t the overarching claim of the speech. The audience you’re addressing being neutral or leaning one way is about who you’re speaking to, not the purpose your speech serves. Visual aids and evidence are tools to support your claim, not the statement that defines what the speech is about.

So, a thesis statement is the concise declaration of the speech’s purpose or main argument, guiding what you will cover and shaping how you present and organize your points.
