Read the following article and select the best answer. Article: Many of us use them several times a day without really noticing. And yet the way we behave in lifts, or elevators as they are known in the US, reveals a hidden anxiety. Passengers seem to know instinctively how to arrange themselves in an elevator, like the dots on a die. With each additional passenger, the bodies shift, going into the open spaces. On your own, you can do whatever you want--it's your own little box. If there are two of you, you take different corners, creating the greatest distance. When a third person enters, you will unconsciously form a triangle. And when there is a square, with someone in every corner, a fifth person is probable going to have to stand in the middle. Why are we so awkward in lifts? "You don't have enough space," says Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin. "Usually when we meet other people we have about an arm's length of distance between us. And that's not possible in most elevators, so it's a very unusual setting. It's unnatural." But perhaps there is more to it than just social awkwardness. "In the back of our minds we are a little anxious," says Nick White, an officer in New York who was unfortunate enough to be trapped in a lift for 41 hours. "We don't like to be locked into a place. We want to get out of the elevator as soon as possible, you know, it's a frightening place to be." During his terrible experience, he began to think of another enclosed space--a tomb. Dr. Lee Gray agrees that a sense of powerlessness is the main cause of lift anxiety. "You're in a machine that's moving, over which you have no control. You cannot see the elevator engine, you don't know how it's working." he says. Question: What does the text mainly talk about? - People's behavior in lifts. - Accidents in lifts. - The function of lifts. - Differences between lifts and elevators.
(Answer)
People's behavior in lifts.

Read the following article and select the best answer. Article: The UK's "hidden" debt mountain stands at an estimated PS5bn, according to a new research today which reveals that as many as one in three consumers are keeping the full scale of their financial problems from their family.The research, for the Post Office, shows that while the average personal debt in the UK is PS9,731.51, people only admit to owing half this when talking to a partner or member of their family. The new report exposes the serious emotional and physical consequences of covering up that debt, ranging from problems at work, sleepless nights and anxiety, to alcohol abuse.A recent report from the Commons public accounts committee said that in the UK, one person in 10 is struggling to manage their debts, while the total of all personal debt is some PS1,500bn.It warned that a government strategy to help consumers struggling with record levels of debt was "seriously deficient" because of poor management and a lack of leadership.The research was commissioned by the Post Office and carried out online by One Poll, which surveyed 2,258 UK consumers. Doug Strachan, director of financial services at the Post Office, said, " The recession has put a massive strain on many families and people may be, for the first time, experiencing levels of debt that they cannot control.The most important thing to remember is that if you do need to borrow money, make sure you are responsible about it and set out a clear repayment plan.Managing the debt effectively can mean there is no need to experience the terrible emotional and physical symptoms hiding debt can result in." Donna Dawson, psychologist specializing in personality, behavior and relationships, said the knock-on effects were enormous, " hiding the extent of debt from a partner or family member may give us a false sense of control or independence, but the reality is that our mental and physical health suffers--and once uncovered, the health of our loved ones suffers as well. The irony is that the very things we are trying to protect--our trustworthiness and our... Question: This passage mainly tells the readers _ . - the phenomenon of people's hiding debt in the UK - the cause of people's hiding debt in the UK - the measures of dealing with hiding debt - the effect of hiding debt

Read the following article and select the best answer. Article: Everybody needs blood Have you ever seen buses on the street for donating blood? Medical workers on board collect blood from volunteers. The blood is then stored up and given to people who have lost a large amount of it due to accidents or diseases. Blood is one of the most important substances supporting our lives. But for now, the only way we can get more of it is through donation. And donated blood has its own problems. First of all, certain blood types are extremely rare. Type O negative blood (O-), for example, only exists in 7 percent of people, according to Sunday Times. There are fewer donors and therefore there isn't enough of this type of blood for everybody who needs it. In addition, donated blood comes from various people, which means that it has to be examined carefully for disease such as hepatitis and HIV to make sure that it's safe for transfusion. This is why scientists all over the world have been trying to make blood in labs. And now, someone finally succeeded--Marc Turner at the Scottish National BloodTransfusion Service has produced blood fit for transfusion, reported Forbes. Unlike many other scientists, who have tried to make blood substitutes by mixing up different ingredients together, Turner chose to grow blood directly from human stem cells . He developed a special technique to create a chemical environment similar to that in our bone marrow . This environment encourages stem cells to develop fully into red blood cell. According to Turner, his version of artificial blood is unlikely to contain disease viruses or produce side effects. And the best part is that what he managed to produce was type O- blood. Not only is it a rare blood type, it's also a universal type, which means it can be transfused into any patient. The new blood is scheduled for human tests in 2016. However, Turner stressed that the new study should not be taken as a signal for people to stop donating blood because it could be another 20 years before... Question: According to the text, a potential danger of blood transfusion is that _ . - it is impossible to store up large amounts of blood - blood transfusion may lead to some terrible infections - it is very hard to find matches for certain blood types - blood transfusion often leads to serious side effects
(Answer)
blood transfusion may lead to some terrible infections
