Question: You may not pay much attention to your daily lift ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, the US, has made it his business to examine this overlooked form of public transport. He is known as the "Lift Guy". "The lift becomes this interesting social space where etiquette  is sort of odd ," Gray told the BBC. "They (Lifts) are socially very interesting but often very awkward places." We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed. He explained that when you are the only one inside a lift, you can do whatever you want--it's your own little box. If there are two of you, you go into different corners, standing diagonally  across from each other to create distance. When a third person enters, you will unconsciously form a triangle. And when there is a fourth person, it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle. New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple--look down, or look at their phones. Why are we so awkward in lifts? "You don't have enough space," Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. "Usually when we meet other people, we have about an arm's length of distance between us. And that's not possible in most lifts." In such a small, enclosed space it becomes very important to act in a way that cannot be construed  as threatening or odd. "The easiest way to do this is to avoid eye contact,"she said. The main purpose of the article is to   _  . A) remind us to enjoy ourselves in the lift B) tell us some unwritten rules of lift etiquette C) share an interesting but awkward lift ride D) analyze what makes people feel awkward in a lift
Answer: B

Question: The Internet brings us many advantages. With the Internet, people can send and receive emails. On the Internet, people can skim over news. Using the Telnet, the user anywhere on the Internet can log into any other machine on which he has an account. It is possible to use the FTP program to copy files from one machine on the Internet to another. But the Internet also brings us troubles. Internet use seems to cause a fall in psychological health, according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often, the twoyear study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the bad feelings. Researchers are puzzled over the results, which were completely opposite to what they had expected. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.The fact that Internet use reduces time used for family and friends may be the reason for the drop in health, researchers said. Faceless, bodiless"virtual" communication may be less psychologically satisfying than actual conversations, and the relationships formed through it may not be so deep. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. "But _ it's _ important _ to _ remember _ this _ is _ not _ about _ the _ technology; _ it's _ about _ how _ it _ is _ used,"said one of the researchers. "It really points to the need for considering social factors when you design new inventions." What may be the reasons why the Internet use causes a fall in psychological health? A) Internet use reduces time used for family and friends. B) Virtual communication is less psychologically satisfying than actuall conversations. C) Exposure to the wider world through the Net makes users less satisfied with their lives. D) All the above.
Answer: D
