TASK DEFINITION: In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
PROBLEM: 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"

SOLUTION: C

PROBLEM: Article: Astronaut Mark Kelly announced today that he is retiring from NASA in order to focus on the recovery of his wife, Gabrielle Giffords. Kelly, who is 47, began his NASA career in 1996. He has traveled to the International Space Station four times and served aboard space shuttles Endeavour and Discovery. Most recently he was commander of Endeavour's final voyage, which ended on June l. "After 25 years of service to our country, I am retiring from the United States Navy and leaving NASA. My retirement will take effect on October l. " he said. "This was no easy decision. Words cannot express my deep gratitude for the opportunities I have been given to serve our great nation. And I have always been proud to be a member of the NASA. Public service has been more than a job for me and for my family. My brother continues to serve in NASA and in the Navy. My parents are retired police officers. And my wife Gabrielle proudly serves in the US House of Representatives." he continued. "As life takes unexpected turns we frequently come to a crossroads. I am at this point today. Gabrielle is working hard every day on her way to recovery. I want to be by her side. Stepping aside from my work in the Navy and at NASA will allow me to be with her and with my two daughters. I love them all very much and there is no doubt that we will move forward together. After some time off, I will look for new opportunities and I'm hopeful that one day I will again serve our country." Kelly said. On Jan 8, Giffords was shot in the head and was severely injured while meeting with her supporters. She returned to her Tucson home last week for the first time since then.

PROBLEM: Article: Everyone talks about the greenhouse effect and how our Earth and its climate are being affected. We can do a science experiment designed by some kids to show this effect and what is happening to the Earth. First prepare the following items: *2 glass containers that need to be the same size and shape *1 gallon plastic bag *4 cups of very cold water *Ice cubes Fill each container with two cups of cold water. Add the same amount of ice cubes to each container. Then put one of the containers in the plastic bag and close it tight. Put both containers in the sun together and keep them there for at least an hour. At the end of one hour remove the container from the plastic bag and immediately check the temperature of the water. After you record this, find out the temperature of the water that is not covered. When you place the containers in direct sunlight, the air inside the bag becomes very warm. The heat filters in but cannot escape so it stays in the closed plastic bag and increases the temperature. What if you leave that for two, three or four hours? Think about what is happening to the Earth. There are chemicals that are creating a type of plastic bag around the Earth. It causes our air to get warmer because of the heat from the sun being kept in this closed area. Think about your car in the hot summer. This is what happens when you leave your car outside all day. This greenhouse effect has caused your car to be so hot that you sometimes cannot even touch the steering wheel. This science project goes to show what affects our planet.
Question: According to the text, the greenhouse effect appears mainly because of _ .
Options: (A) the hot sunlight (B) chemicals around the Earth (C) the plastic bag (D) human activities

SOLUTION:
B
