In a paragraph about renewable energy, which statement correctly identifies the topic?

• A. The central point about renewable energy.
• B. The writer's purpose.
• C. The supporting details.
• D. The subject being discussed is renewable energy.

Answer: (D)

Recognizing the topic of a paragraph—the subject being discussed—is what this item is testing. In a paragraph about renewable energy, naming renewable energy as the thing the paragraph is about correctly identifies the topic. The other ideas describe different parts of a paragraph: the central point or main idea is what the paragraph says about the topic; the writer’s purpose is why the author is writing; the supporting details are the facts and examples that back up the main idea. So stating that the subject being discussed is renewable energy shows you’re identifying the topic itself, which is the correct choice.
