Answer:
B. Highlighting many key points
Explanation:
In my opinion this makes sense as the best answer since you can easily skim through any text, but to recognize key points requires that you understand the material.
1. an entry in the catalog listed under the topic or subject of the book - subject entry
2. a listing of books in a library - catalog system
3. an entry in the catalog listed by the author's name - author entry
4. an entry in the catalog listed under the title of the book - title entry
