Question: Article: On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030.Our expanding waistlines lead to not only a medical problem, but according to a recent article in The New York Times, it could also endanger personal safety in some situations-in an airplane crash, for example. The New York Times' Christine Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength -first set more than 60 years ago---require that the seats be made for a passenger weighing 170 pounds(77kg).Today, the average American man weighs nearly 194 pounds(88kg) and the average woman 165 pounds(75kg).Negroni reports: "If a heavier person completely fills a seat ,the seat is not likely to behave as intended during a crash,"Robert Salzar,the leading scientist at the Center for Applied Biomechanics at the University of Virginia. "The energy absorption(,) that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly". "Nor would the injury be limited to that passenger only," Dr. Salzar said. "If a seat or a seat belt fails,"he said, "those people who are seated nearby could be endangered from the uncontrolled movements of the passenger." Most complaints about airplane seats focus on their lack of comfort and high ticket price, and whether overweight passengers should be made to buy two seats. But The New York Times' article bring up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem.Experts agreed that crash testing should be done with overweight dummies .Both airplane seats and seat belts should be tested, _ said. Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board's investigators have never seen an accident involving a commercial plane in which the weight of a passenger was a problem.
Question: What is the article in The New York Times mainly conceerned with?
Options: (A) The size of airplane seats and seat belts (B) Safety of overweight airplane passengers (C) Airplane crashes involving commercial planes (D) A medical problem caused by being overweight

Question: Article: If you were walking around a supermarket and saw a woman with a shaved head, a ring through her nose, a tattoo design on her arm and she has a small child in her shopping _ , what would your opinion be? Do you think this kind of body decoration is attractive or ugly? Different people have different ideas. The following are some examples of body decoration from around the world. In many parts of Africa, it is thought that an attractive girl should have really shinny skin. On Bali, a little island in Indonesia, they believe that a beautiful woman or handsome man must have perfectly straight, flat teeth. The Balinese believe that teeth with pointed edges make you look like an ugly wild animal. So when a girl or boy becomes a teenager, he or she is taken to a special person in their village who will file off teeth points to make them smooth and flat. There is no anesthetic and this tooth filing is really painful. It is a kind of test. If you can stand it without screaming or crying too much, then you are thought ready to become an adult. In Myanmar, there is a small group of people who are called the "Papaung". They believe that a woman can only be really beautiful if she has a long neck. I mean a VERY long neck. Now you might think that you are either born with a long or short neck and that there's nothing whatever you can do about it. But you would be wrong! At around the age of 5, a Papaung girl has heavy metal rings fitted around her neck, tightly between the chin and shoulders. Each year more rings are added and very, very slowly their weight pushes the shoulders down, in this way making the neck look longer. A Papaung woman will wear her neck rings all her life, never once taking them off. So now I'm sure you will all agree that different people have different ideas about what is beautiful.

Question: Article: The college entrance exam is not only a big challenge for Chinese high school students, but also a very important exam in the lives of South Korean students. Although the long, cold winter has already started in South Korea, the annual national exams have made the atmosphere very heated. More than 675,000 South Korean high school graduates took the college entrance exam last Wednesday. They usually take exams in Korean, maths, sociology , history and foreign languages. Officially there is one college place for every 1.33 students. But because all the students want to go to the top universities in the country, the competition can reach one place for 10 students. The students want to attend these colleges for both their famous names and better job opportunities. Because students face fierce competition, they have to study very hard to realize their dreams. Park Seung said he and his classmates often go to school before 7:30 a.m. After school has finished at 6:30 p.m., most of them go to the library to continue their study instead of returning home. Since many libraries in South Korea are open 24 hours a day, they often stay long into the night. Many of the Senior 3 students only sleep for three to four hours a day. "I feel a lot of pressure, but I have to study very hard in order to make my dream come true. This is my lifetime goal and it will be a turning point in my life which could decide my future," Park said. The exam day is a very serious day for the whole of South Korea. Vehicles are not allowed within a 200-metre radius of all the test sites to make sure the students have quiet surroundings. Tooting of horns is forbidden, even airplanes are ordered to avoid landing and take-off near the test sites during listening comprehension test hours. Students are told their scores in December before they apply for college. This is followed by face-to-face oral tests. There are public and private universities in South Korea. Many private universities are well-known, but their fees can be 18, 000 yuan each term. This has made a lot of students think again.
