Example Input: Article: You know you have to read "between the lines" to get the most out of anything. I want to persuade you to do something equally important in the course of your reading. You have to "mark between the lines". By marking you can make the most efficient kind of reading. There are two ways in which one can own a book. The first is the property right you have by paying for it, just as you pay for clothes and furniture. While full ownership comes only when you have made it a part of yourself and the best way to make yourself a part of it is by writing marks on it. Why is marking up a book _ to reading? First, it keeps you awake. Second, active reading is thinking, and thinking tends to express itself in words. Finally, marking helps you remember the thoughts you had, or the thoughts the author expressed. Reading a book should be like making a conversation, a conversation between you and the author. Although he knows more about the subject than you do, don't let anybody tell you that a reader is only on the receiving end. Understanding is a two-way operation. Reading doesn't mean being a passive empty receiver, the reader has to question himself and question the author. And marking a book can show his own judgment on author's opinion: agreement or difference.

Options: (A) the most important of all (B) more important than "reading between the lines" (C) as important as "reading between the lines" (D) not so important as "reading between the lines"
Example Output: C

Example Input: Article: Many people cannot start their day without first having a cup of coffee or tea.These drinks help them think clearly and feel more awake.This is because of caffeine,which helps to give a jump start to the nervous system.Now,a report says it may also boost long-term memory. Mike Yassa is a neurobiology professor.He and other researchers wanted to know if caffeine could improve a person's memory.He explains,"After you learn anything,it takes some time for that memory to strengthen.And over the first 24 hours is actually where most of the forgetting happens.So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting." They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house, or outdoors.Then some of the subjects were given a caffeine pill.The others were given a placebo--a pill containing nothing. 24 hours later,the subjects were shown the exact same images from the day before.They were also shown images with slight differences,and some completely new images. Both groups correctly identified the exact same and completely new pictures.But those who took the caffeine pill were better at spottingthe pictures that were slightly different. Professor Yassa says their answers helped to show the effects of caffeine on memory. And we find that if they are on caffeine they are much more likely to make the right decision." The amount of caffeine the researchers used in the study was similar to one cup of strong coffee.The researchers did not see any improvement to memory from smaller doses of caffeine or when it was given an hour before viewing the images.
Question: What is the focus of the text?
