What is the purpose of including a preview in the thesis statement?

• A. To outline the main points that will support the claim.
• B. To provide a random list of sources.
• C. To present a separate argument.
• D. To only set the tone with a quote.

Answer: (A)

The key idea is that a thesis statement with a preview gives the reader a roadmap of what the essay will argue and how it will be organized. By naming the main points you will address, the thesis helps readers anticipate the structure and purpose of your argument, and it keeps your writing focused as you develop evidence for each point. This clarity also helps you stay on track, showing why each piece of evidence belongs and how it supports the claim.

The other options don’t fit that role. A random list of sources belongs in a bibliography or literature review, not in the thesis preview. Presenting a separate argument would muddle the thesis by introducing multiple claims rather than a single, clear claim supported by specific points. While a quote can set tone, it doesn’t outline the points you’ll cover, so it won’t provide the roadmap readers rely on.
