Why is underlining rules, formulas, and important statements in textbooks beneficial?

Underlining rules, formulas, and important statements in textbooks is beneficial primarily because it creates a stronger impression of the material. When you underline specific concepts, it draws the reader's attention directly to those key points, enhancing focus and retention. This technique emphasizes the significance of the information, which helps in better comprehending and recalling the material later.

By highlighting critical aspects, learners can more easily differentiate between ordinary text and essential details. This proactive engagement with the text improves the overall learning experience, aiding in the mastery of the subject matter.

While the other choices may touch on aspects related to improving text interaction, they do not capture the primary purpose and benefits associated with the act of underlining in an educational context.
