Which statement best describes how to identify the main idea?

• A. Look for the sentence that captures the central point supported by details
• B. Read the title only
• C. Count the number of paragraphs
• D. Find the author’s name

Answer: (A)

The main idea is the central message the author wants you to understand—the one idea that everything in the text is building toward. The best clue is the sentence that clearly states that central point or thesis, the line that ties all the details and examples together. Details in the paragraph support that idea, showing why it’s true or important.

Reading the title might give a hint about the topic, and the number of paragraphs can tell you about structure, but they don’t by themselves reveal the main point. The author’s name has no bearing on the central message. So the sentence that captures the central point, supported by the details, is the clearest guide to identifying the main idea.
