Article: Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter? More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language. You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer. Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and State University of Campinas are both highly ranked internationally. Your money will go a long way there, too. Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.

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.
Question: The author thinks "marking between the lines" is _ .
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"

Ex Output:
C
