Question: Article: Have you heard of the scandal that happened in one of Great Britain's biggest supermarket chains called Tesco? The British love Tesco as it sells very cheap products and it can be found on almost every corner of a British city or town. On January 15th 2013 food inspectors discovered 30 % horsemeat in a certain brand of frozen beefburgers that were mostly sold by Tesco in the UK and Ireland. In times of social media like Facebook and Twitter the news has spread fast and customers have been very concerned about what the food they buy actually contains. Tesco said it had taken away the burgers from the shop shelves immediately, and apologized to their customers. They also promised that they would find out what exactly happened and that they would work harder than ever so this would never happen again. Customers are also able to return the beefburgers and get a refund, that is, their money back. However, it will be hard for Tesco to get the people's trust back. Just imagine buying lovely beefburgers that you fry at home and suddenly you find out that you have actually eaten horsemeat! In this case not only horse lovers will be upset! By the way, why are British people so shocked about eating horsemeat? In history, horses have played great roles as working animals and as an important means of transport. When Britons of today think of horses, they think of majestic animals or cute pets rather than meat. But this is not the only reason for the protest: Customers also want to be sure that the products they buy contain what it says on the label. Hopefully, supermarkets can avoid mistakes like that in the future. Maybe there should be stricter regulations and more controls of our food? Otherwise we will soon find ourselves eating panda meat instead of pork and parrot instead of chicken. So the next time you are in a supermarket maybe check the ingredients of your food before you buy it or you could get a nasty surprise ...

Question: 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"

Answer: C

Question: Article: Fruit or juice, which is nutritionally superior? This is almost the same as the age-old question: The chicken or the egg, which came first? Usually, juicers remove the juice and some pulp from fruits and/or vegetables.It takes a lot of fruit to make a container of juice.We do get all of the vitamins, minerals, beneficial plant chemicals and carbohydrates in juice out of a whole fruit.But we do not get much of the fiber, the part that aids our digestive process, fills us up, and may help protect us against heart diseases and certain cancers. However, you may be surprised to discover that some juices actually contain more necessary nutrients .For example, apples are not a good source of vitamin C, but many types of apple juice are fortified with vitamin C. Juice has more calories than fresh fruit due to added sugar and less fiber.If calories are your primary concern, choose fresh fruit over juice and drink water if you are thirsty.We do not feel as filled up from juice because it does not contain any fiber.For many people, drinking a caloric beverage , such as juice, is not as satisfying as eating the same amount of calories in food.For those of us who need to increase caloric intake (such as athletes, children, or teens) juice is a GREAT choice. Kids love the taste of pure fruit juice, and parents love it because it is a healthy source of nutrients.But avoid junk fruit beverages which are mistaken for juice blends that contain various fruits like grape, apple and pear.These juices do not have the natural levels of vital nutrients that 100 percent pure juices like orange juice provide.
Question: According to the passage, you'd better have _ to help prevent heart disease.
Options: (A) fruits (B) juice (C) calories (D) minerals

Answer:
A
