Answer:
Entire sections
Step-by-step explanation:
It is impracticable to make notes everything the teacher says. In other words, it is impossible and unnecessary to make annotations of entire sections, so we end up having to select some parts, which we consider most important, to transfer to the annotation. What becomes annotation is precisely what was processed by the brain as important. That's where the cat's leap is: notes should be made with small texts that help you remember what to study. For this reason, annotations should be made through a section's Topics, important examples, keywords, and their definitions.
