How are the main idea and supporting details related?

• A. Supporting details extend or elaborate the main idea.
• B. They are completely separate.
• C. The main idea is only in the title.
• D. Supporting details contradict the main idea.

Answer: (A)

The main point of a passage is the central idea the writer wants you to take away, and the supporting details are the facts, examples, reasons, and descriptions that explain, justify, and expand that point. They make the main idea clearer and more convincing by providing concrete evidence or illustrations. For example, if the main idea is that regular exercise improves overall health, the supporting details might describe how exercise strengthens the heart, boosts mood through endorphins, helps control weight, and is supported by research. Those details are not random facts; they directly extend and illuminate the central idea. That’s why the other options don’t fit: the main idea isn’t simply a separate idea, not everything is only in the title, and supporting details aren’t meant to contradict the main idea. They are meant to reinforce and deepen it.
