[EX Q]: Article: Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children's bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging . Scientists measured this by studying the ends of children's chromosomes , called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry. Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person. In this study, researchers examined whether exposure to violence could make children's telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children's telomeres--in cells obtained from the insides of their cheeks--at ages 5 and 10. Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers. Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says. The study confirms a smallbutgrowing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

[EX Q]: Article: When we donate blood, a small amount is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-. The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances contained in each type, the four groups must be _ carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital. There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The least common is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world.
Question: The writer suggests that the third most common blood type among the Europeans is _ .
Options: (A) B (B) A (C) AB (D) O
Asnwer: A
[EX A]: Yes

[EX Q]: Article: I was on vacation, and in my mind, vacation does not mean setting my hotel room alarm clock for 6 am. But when you're in Aruba and hoping to reserve a beachside palapa , that's exactly what you do. Tourists begin lining up at the crack of dawn to secure these umbrella-like wood structures that are covered with dried and woven palm leaves. They then place towels on chairs and call them theirs for the day, whether they remain there or not. I knew nothing of _ on my first day in Aruba. I saw an empty chair covered with a towel and took it. It was a big mistake. For many visitors, a week bathing in the sun is the only activity they wish to pursue. It sounded good to my girlfriend, Barbara, and me after Boston's awful winter. Six more inches of snow was predicted on the day we left. The sun, the sand, and the beach seemed just about right. Aruba's slogan is "One Happy Island", and it doesn't take long to understand why. Aruba is said to be on "island time". Translation: No one is in a rush to do anything. When in Aruba, you go with the flow, however slow and lazy that might be. Cooling trade winds, white sandy beaches, turquoise waters, and dazzling sunsets are all good reasons to visit. But this 20-mile island offers more than lazy days walking on the beach. There is amazing night life, casinos, golf, scuba diving , fine dining, shopping, and a great national park. But our first day was spent as you'd expect, swimming in the sea and enjoying cool drinks. Our drink of choice quickly became the Coco Loco. It's as refreshing as it sounds.
Question: Tourists get up at 6 am because they _ .
Options: (A) want to see the sunrise early (B) need to check out early (C) want to have fun longer (D) need to reserve a beachside palapa
Asnwer: D

Yes
