What is the purpose of evaluating supporting details in a passage?

• A. To argue against the main point
• B. To provide evidence that supports the main point
• C. To memorize every sentence
• D. To ignore the text's structure

Answer: (B)

Evaluating supporting details is about reading the evidence the author provides—examples, statistics, quotes, and other facts—and judging how well that evidence backs the main idea. When you examine these details, you consider whether each piece really connects to the claim, whether it’s specific and credible, and whether it strengthens the overall argument. The goal is to see that the main point is supported by relevant, convincing details, which helps you understand the author’s purpose and assess the effectiveness of the passage. Details that don’t fit or that mislead would weaken the point, so the focus is on how evidence reinforces the main idea, not on arguing against it, memorizing every sentence, or ignoring how the text is structured.
