"Mahru" has been developed to imitate humans and can move its lips, eyes and eyebrows. The machine can also move its upper and lower body freely and automatically stop itself when walking. In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions. The 1.5m tall robot was produced by researchers at the Korea Institute of Science and Technology(KIST)and is the first South Korean-developed machine of its kind. "Mahru will open the way for the commercial use of humanoid robots doing housework," You Bum-Jae, leader of the development researchers team, said, "Mahru can dance while walking on its legs and is able to work in place of a human." Through an advanced action capture system, Mahru can follow a variety of human movements and is able to move its hands freely enough to cope with any obstacles that may get in his way when walking. State-funded KIST showed the robot during a presentation at its headquarters in Seoul. People were treated to an entertaining show which saw the robot show off the full range of its skills, a series of dance moves. The research team added that they had designed another "Mahru", this time with sensors allowing it to distinguish between faces and objects. The showing of "Mahru" came a week after researchers in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan said that "robotgirl", Replee R-l, looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch. Question: Which is the best title for this passage? - A commercial robot - A robot produced by Japan - A human-like robot - A dancing robot

Read the following article and select the best answer. Article: In addition to writing articles and books, Mark Twain delighted the audience with his public lectures about the faraway places he visited on his travels. People were eager to learn about his trips to places like the Sandwich Islands (now Hawaii), Egypt and the Holy Land. Twain often used the fees he earned from his lectures to pay for more adventures. His well-attended performances also served to bring attention to his published work. At that time, the public lecture was a very popular form of entertainment, and audiences' expectations ran high, but Twain never failed to amuse them. Twan also wrote on amusing subjects. In 1873, he released a book called The Gilded Age. The book was a satire of the very wealthy of the time. A satire is a work that makes fun of bad human behavior, such as wasteful spending. Twain made people laugh at the excesses of the rich. In 1889, Twain took on other members of the Establishment. He wrote A Connecticut Yankee in King Arthur's Court, about a boy who travels back to the time of King Arthur. Twain made fun of those who were given advantages not because they had earned them but because of their family connections. If you have never read any of Mark Twain's works, try reading A Connecticut Yankee in King Arthur's Court, The Adventures of Huckleberry Finn, or The Adventures of Tom Sawyer. They will make you laugh. Question: What's the author's attitude towards Mark Twain? - Interested. - Admiring. - Disappointed. - Indifferent.

(Question)
Read the following article and select the best answer. Article: Imagine this situation. You pass a group of people. The people are talking to each other. You cannot hear what they are saying. But suddenly they start laughing. What would you think? Would you think they were laughing at something funny that one of them said? Or -- be honest with yourself -- would you think they were laughing at you? Yes, you. Being laughed at is a common fear. But a major study published in two thousand and nine found that this fear is not the same around the world. It differs from culture to culture. People in Finland were the least likely to believe that people laughing in their presence were making fun of them. Less than ten percent of Finns in the study said they would think that, compared to eighty percent of people in Thailand. Some people in the study said they felt unsure of themselves in social situations but hid their feelings of insecurity. Others said they avoided social situations where they had been laughed at before. The study found that people in Turkmenistan and Cambodia were more likely to be in the first group. They would hide their feelings of insecurity if they were around other people's laughter. But people in Iraq, Egypt and Jordan were more likely to try to avoid such situations if they felt they had been laughed at before. Shy people often avoid situations that would force them into close contact with other people. They worry that something they say or do will make other people laugh at them. But some people worry much more than others. They may have a disorder called gelotophobia. Gelos is a Greek word. It means laughter. Phobia means fear. This fear of laughter can be truly sad for those who live with it. It can affect how they lead their lives. In the study, a team from the University of Zurich led more than ninety researchers from around the world. They wanted to understand the difference between normal shyness and true gelotophobia. Another purpose of the study was to compare the levels of fear of being laughed at in different cultures. The researchers surveyed...
