Which of the following strategies involves looking for key phrases?

The strategy of highlighting important sentences specifically involves looking for key phrases. By identifying and emphasizing these phrases, you can easily pinpoint central ideas and critical information within a text. This act of highlighting serves as a visual aid, allowing you to focus on the most significant parts of the material, which can be crucial for understanding and retaining information.

Other strategies, such as listening carefully, reading aloud, or taking breaks, serve different purposes. Listening carefully enhances comprehension through auditory processing, reading aloud emphasizes pronunciation and rhythm, and taking breaks can help manage fatigue and improve concentration but does not specifically target key phrases. Highlighting, however, distinctly centers on identifying and marking essential concepts in the reading material, making it the most effective approach for that specific task.
