Which statement best describes the relationship between the thesis statement and a paragraph's topic sentence?

• A. The thesis statement expresses the main argument, while each topic sentence introduces the main idea of its paragraph.
• B. They are interchangeable.
• C. The topic sentence restates the thesis in every paragraph.
• D. The thesis statement is a conclusion drawn from the topic sentences.

Answer: (A)

The main idea being tested is how a single, overarching claim connects with the individual points introduced in each paragraph. The thesis statement presents the overall argument of the essay—what you’re trying to prove. Each paragraph then focuses on a specific aspect that supports that argument, and its topic sentence states the paragraph’s main idea. That topic sentence serves as a clear guide to the paragraph’s purpose and shows how this part of the essay backs up the thesis. When you read the essay as a whole, the theses’ claim is reinforced by each paragraph proving a piece of that claim, creating unity and coherence from start to finish. This is why the described relationship is the best fit: the thesis is the main argument, and each topic sentence introduces the paragraph’s main idea that directly supports that argument. The other ideas don’t fit because they either imply interchangeable roles, suggest restating the thesis in every paragraph, or imply the thesis comes only after the body is done instead of being the guiding claim throughout.
