In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks, and shirt as he went. He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator was swimming toward the shoe. His mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, shouting to her son as loudly as she could. Hearing her voice, the little boy became worried and made a return to swim to his mother. It was too late. Just as he reached her, the alligator reached him. From the bank. the mother caught her little boy by the arms just as the alligator _ his legs. That began a tug-of-war between the two. The alligator was much stronger than the mother, but the mother was much too determined to let go. A farmer happened to drive by, heard her screams, raced from his truck, took aim and shot the alligator. After weeks and weeks in hospital, the little boy survived. His legs were extremely scarred by the attack of the animal and on his arms were deep scratches where his mother's fingernails dug into his flesh in her effort to hang on to the son she loved. The newspaper reporter, who interviewed the boy after the injury, asked if he would show him his scars. The boy lifted his pants legs. And then, with obvious pride, he said to the reporter. "But look at my arms. I have great scars on my arms, too. I have them because my mom wouldn't let go. Question: Why did the farmer help the mother? Options: A: He didn't want to see the alligator killing the boy. B: She was much too determined to let go of the boy. C: Her nails dug into the boy's flesh to hang on to the boy. D: The boy lifted his pants legs to show his scars.

Read the article and select the best answer. Article: As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that. Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere. A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy. Boaz Leupe, CEO of the start-up Nerdalize, says it's actually quite simple."We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe. The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center," says Leupe. One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server's processors so it cannot be used as the primary source. But he is ready to try it. "If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills." Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in... Question: Which one is true according to the passage?

Read the article and select the best answer. Article: A funny thing happened on the way to the communication revolution: we stopped talking to one another. I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and suddenly, I became invisible, absent from the conversation. The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communication technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice-mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine. As almost every contact we can imagine between human beings gets automated, the emotional distance index goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated. I am not against modern technology. I own a cell phone, an ATM card, a voice-mail system, and an email account. Giving them up isn't wise. They're a great help to us. It's some of their possible consequences that make me feel uneasy. More and more, I find myself hiding behind email to do a job meant for conversations or being relieved with voice-mail picking up because I don't really have time to talk. The industry devoted to helping me keep in touch is making me lonelier. Question: Which of the following would be the best title of the passage? Options: A: The Advance of Modern Technology B: The Consequences of Communication Technology C: The Story of Communication Revolution D: The Automation of Modern Communication
(Answer)
