What is the function of a topic sentence in a body paragraph?

• A. Close the paragraph
• B. To introduce the paragraph’s main idea and link to the thesis
• C. List supporting details
• D. Provide evidence without context

Answer: (B)

The function being tested is to set up the paragraph’s purpose by presenting its main idea and linking it to the thesis. A strong topic sentence announces what this paragraph will argue, giving the reader a clear focus and a sense of direction for the evidence and analysis that follow. By tying the paragraph to the overall argument, it helps the essay stay cohesive and shows how this point contributes to the larger claim. The topic sentence should present a specific claim that the rest of the paragraph will support with details, rather than simply listing evidence or serving as a closing thought.
