Why is underlining rules, formulas, and important statements in textbooks a good practice?

• A. It creates a stronger impression
• B. It helps memorize every word
• C. It wastes time
• D. It has no effect

Answer: (A)

Underlining key rules, formulas, and statements is a form of active reading. By marking what's most important, your attention is guided to the ideas you’ll need to recall later. This makes those parts stand out visually, creating a stronger mental imprint and serving as quick clues during review. When you skim the page and see the underlined sections, you can rapidly locate the essential concepts and trigger related memories, which strengthens retention. This approach isn’t about memorizing every word, but about focusing on the ideas that matter and encoding them more deeply. It’s most effective when used selectively and followed by brief review or notes, so the markings reinforce understanding rather than just marking text for the sake of it.
