During a Recent Class, Yuri's Instructor Recommended That Students Use

During a recent class, Yuri's instructor recommended that students use marking to help improve their comprehension of the assigned reading. But Yuri never used marking in high school because the textbooks belonged to the school and he wasn't allowed to write in them. Thus, he is unsure of how to mark his textbook effectively and asks your advice. What should you tell him?

A) Highlight or underline as much information in the chapter as possible.
B) Begin highlighting or underlining information while previewing the chapter.
C) Finish marking the whole chapter before you begin taking notes.
D) Read before you mark and reflect on the key ideas before you mark.
