Question: Read the following article and select the best answer. Article: Scientists have created a " human-like robot" that can dance and do the housework. " Mahru" has been developed to imitate humans and can move its lips, eyebrows and pupils . 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 1.5 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 research team ,said. "'Mahru' can dance while walking on its legs and is able to work in place of a human." Through an advanced motion capture system, "Mahru" can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking. State-funded KIST showed the robot during a presentation at its head office in Seoul. People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s 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 researcher in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan claimed that " robogirl", Repliee R-1, " looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch." Question: When Mahru" meets something in its way, it will be likely to _ . - go around it - turn back quickly - deal with it using its hands - ask humans for help
Answer: deal with it using its hands

Question: Read the following article and select the best answer. Article: Last year I lived in Chile for half a year as an exchange student with the American Field Service. Compared to most visitors, I didn't travel much. I lived with a Chilean family and had the responsibilities of any Chilean teenager. I went to school every day, in uniform. I had good days and bad days and days that I didn't understand. Chuquicamata, my host community, is a mining camp in the Atacama Desert. There is no disco, no shopping center, no museum or beach. Driveways must be watered daily to keep the dust down. When I arrived here, I was scared. It was so different from the urban middle-class America I was accustomed to. There were lost dogs on the streets, and a constant cloud of brick-colored dust came from the mine. There was no downtown, few smoothly paved streets, and little to do for amusement. The people worked extremely hard. Rain was a rare phenomenon; earthquakes and windstorms were frequent. I had studied Spanish for two and a half years and was always one of the best students in my class. But in my first week in Chile I was barely able to communicate and desperate for one person to whom I could explain my shock. I couldn't speak the thoughts in my head --- and there were so many. Most exchange students experience this like me. Culture shock presents itself in everything from increased aggression toward the people to lack of appetite or weight gain and depression. I was required to overcome all difficulties. Being an exchange student is not easy. As time passed, everything changed. I began to forget words in English and to dream in Spanish and love Chilean food. I got used to not depending on expensive things for fun. Fun in Chuquicamata was being with people. And I took math, physics, chemistry, biology, Spanish, art, and philosophy --- for which I received half a credit in global studies. Somehow my high school couldn't figure out a way to relate my experience to its curriculum. But the sacrifices were nothing compared to the gain. I learned how to accept as well as to succeed in another... Question: On arriving in Chile, the author felt frightened because _ . - he couldn't get used to working so hard as Chileans did - he did not know how to get along with local people because of the culture gap - its living conditions were much worse than what he was familiar with - his life was threatened by earthquakes and windstorms
Answer: its living conditions were much worse than what he was familiar with

Question: Read the following article and select the best answer. Article: More than 40 years ago, John Williams gave away all of his belongings and went off to the mountains to live the way people lived 100 years ago. For food he traps wild animals, fishes in the rivers, and plants whatever he can. John lives in a cabin he made by hand, out of trees he chopped down with an ax. Though he has no s he knows of, he does have a deer he raised from a fawn. The deer lives in the house in the winter and goes with John when he goes into the forest for food. Nobody lives within fifty miles of his cabin in the mountains and John has not been out of the mountains during the entire forty years. One day last year I hiked in to see how John lives. It was like going back in time. There were no roads, no stores, no noise, no pollution, not even a post office. Most notable of all, there were no people and that's just the way John Williams wants to keep his part of the world--without people. But there is a paradox in his story. John is an educated man. He has books and nobody knows how he got them. Mostly he reads about his world, the forest, the animals, the plants, and the mountains. He has seen airplanes flying overhead but does not want to know about them. For him, electricity is lightning, not light bulbs, refrigerators, televisions, or washing machines. John Williams is 85 years old and had not had a sick day in his life. He attributes his long life to the fact that it has nothing to do with people and in order that he might enjoy many more years of health, happiness, and solitude, I will not tell you where his kingdom lies. There is no room there for you or me. Question: John Williams has lived in his present location _ . - since he was born - since his wife died - almost half his life - since he graduated from college
Answer:
almost half his life
