Article: A new smart phone system under development can locate you even when you're inside a building, which GPS can't do. While the concept sounds powerful, it's not yet clear how practical it might be. The set-up, called SurroundSense, sends information from cameras and microphones--gear in the latest smart phones--to a server that produces a fingerprint of the location. "You can't tell much from any of the measurements individually, but when combined, the optical , acoustic and motion information creates a unique fingerprint of the space," said Ionut Constandache, a student in computer science. The system distinguishes between two indoor spaces in this manner: It knows that a bar is likely to be dark and noisy and people move little, sit a lot, whereas a department store will be brightly lit, contain vibrant colors, and will see a lot of people moving up and down passages. The more the system is used, the more it learns about specific places. More work is needed before the set-up would be ready for prime time, however. For now, it can't work if a person's cellphone is in a handbag or otherwise unable to employ the camera. Finally it would be best served if paired with phones that were worn on the wrist or hung around the neck. Batteries, too, are a problem. Students on the research team went out across Durham, North Carolina, with their cellphones collecting data in different types of businesses. The students mirrored the actions of the selected customers so that they would not prejudice the measurements. "We went to 51 different stores and found that SurroundSense achieved an average accuracy of about 87 percent," Constandache said. "As the system collects and analyzes more and more information about a particular site, the fingerprint becomes more precise," said Romit Roy Choudhury, professor of computer engineering. "Not only is the _ different at different locations, but also can be different at different time at the same location." Question: Why did students mirror the actions of the selected customers? Yes or no, is the answer "To get a reasonable result."?
Yes

Article: Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time. One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he'd better not go there. Mark Twain waved his hand and said, "It doesn't matter. The mosquitoes are no relatives of mine. I don't think they will come to visit me." After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. "I'm very sorry, Mr. Mark Twain. There are too many mosquitoes in our town." One of them said to him. Mark Twain, however, made a joke, saying to the waiter, "The mosquitoes are very clever. They know my room number. They didn't come into the wrong room." What he said made all the people present laugh heartily. But that night Mark Twain slept well. Do you know why? That was because all the waiters in the hotel were driving the mosquitoes away for him during the whole night. Question: From the story we know _ . Yes or no, is the answer "no mosquitoes troubled Mark Twain in the night"?

No

Ques: Article: A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy and speed,The Telegraphreported. Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side. The company gave 26 participants a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all. The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, toldThe Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... _ are going to become more positive about the work." However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you. Question: Which of the following can be the best title for the passage? Yes or no, is the answer "Music helps us to learn"?
Ans: No

Ques:Article: My mother celebrates her 90th birthday today. She has asked me to keep it a secret and tell people she is only 89. For some reason she seems to think this sounds better. We really have our share of disagreements, but on this one I stand firm: I think 90 sounds pretty fantastic. My mother says she never thought she would live this long. She was weak and had two near fatal illnesses under the age of 12. And then there was the fear of cancer. Her mother died of breast cancer when my mother was just 17, at a time when there was no such thing as Breast Cancer Awareness Month. When I was 17 years old, I was worried that my life would parallel hers. I never shared my fears. Instead I would lie awake at night in my bed with the yellow and orange flowered bedspread she had made for me, counting how much time we had left together. What I didn't know until years later was that she had had the same fear. She told me how she would write away for every piece of information she could find on how to prevent the fatal disease until my father made her stop. He told her she had to relax and stop worrying so much. She was going to be OK. He was right. And one October, many years into the future, we would celebrate her 90th birthday. My mother is the reason I live the life I do. Her fierceness and independence was how I learned to walk the path I have chosen. She was always a forward thinker, reading up on what's new and willing to try something different. She taught me kindness and to look out for those less fortunate than us. When Dad died far too young, my mother was the one who sat me down the afternoon after the funeral and told me life would go on, and that as hard as it was to imagine, I would be happy again. She helped me to understand that death was a part of life we could never escape and we must learn to accept it. Our roles have changed in recent years. She turns to me for help now. She asks me what to do. She is the one to call me when she is worried or concerned or needs help with something. I am the one who...
