In debate, what is a 'thesis'?

• A. A Central Claim or Main Argument
• B. A Closing Remark
• C. A Rhetorical Device
• D. An Example

Answer: (A)

A thesis in debate is the central claim or main argument you are defending. It states a clear position on the issue, one that can be debated and supported with evidence. A good thesis is specific and focused, guiding the entire argument so your evidence, reasoning, and examples all work toward convincing judges of that single point.

Think of it as the anchor of your speech: it sets the direction and helps you organize your points around a single, defendable position. By contrast, a closing remark is what you say at the end to summarize and persuade after the argument is built, a rhetorical device is a technique to persuade rather than the main claim itself, and an example is a specific instance you use to illustrate a point but not the claim you’re arguing.
