Article: I was in a strange city and I didn't know the city at all and what is more,I could not speak a word of the language. After having spent my first day in the town-centre,I decided to lose my way on my second day, since I believed that this was the simplest way of getting to know the strange city. I got on the first bus that passed, rode on it for several stops then got it off and walked on. The first two hours passed pleasantly enough. Then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way. The trouble was that the only word I knew of the language was the name of the street in which I lived and even then I pronounced it badly. I stopped to ask a friendly-looking newspaper-seller. He smiled and handed me a paper. I shook my head and repeated the name of the street and he put the paper into my hands. I had to give him some money and went on my way. The next person I asked was a policeman. The policeman listened to me carefully, smiled and gently took me by the arm. There was a strange look in his eyes as he pointed left and right and left again. I thanked him politely and began walking in the direction he pointed. About an hour passed and I noticed that the houses were getting fewer and fewer and green fields were appearing on either side of me. I had come all the way into the countryside. The only thing left for me to do was to find the nearest railway station, Question: The policeman _ . Yes or no, is the answer "didn't understand what he really meant"?
No

Article: It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report. Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night. "It wasn't the moon," was the reply. They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn't smoke because it didn't change its shape. It was moving in a regular way. That is to say, it didn't go suddenly faster or more slowly, and it didn't go higher or lower. So the two men decided that there must be men in it. After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness. When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast. On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken? Question: UFOs are _ . Yes or no, is the answer "strange flying objects"?

Ques: Article: The strong emphasis on educational achievement in China, Japan and other parts of South-East Asia may be coming at a heavy price. Researchers say that hard work at school plus the lack of exposure to outdoor light is damaging the eyes of almost nine out of ten students--with one in five at serious risk of visual impairment and blindness. The scientists say that young people need up to three hours a day of outdoor light, but many infants are also missing out as they nap during lunch time. Dr. Ian Morgan is the lead author of the study. "I think what's happened in South-East Asia is that we've got _ . We've got the massive educational pressures and we've got the construction of a child's day in a way that really minimises the amount of time they spend outside in bright light." The scientists say that genetic factors, long thought to play a big role in short-sightedness, are not as important as the environment. They point to Singapore as a place with several different racial groups, all of whom are now suffering high levels of short-sightedness. The authors suggest that compulsory time outdoors should be considered by educational authorities across South-East Asia as a way of dealing with the problem. Question: What does the passage mainly talk about ? Yes or no, is the answer "Sight problems in South-East Asia."?
Ans: No

Ques:Article: A new study suggests that sad music might actually arouse positive emotions. The finding helps to explain why people enjoy listening to sad music, say Ai Kawakami and her colleagues from Tokyo University of the Arts and the RIKEN Brain Science Institute, Japan. Ai Kawakami and her colleagues asked 44 volunteers, including both musicians and nonspecialists, to listen to two pieces of sad music and one piece of happy music. Each participant was required to use a set of keywords to rate both their perception of the music and their own emotional state. The sad pieces of music included Glinka's La Separation in F minor and Blumenfeld's Etude Sur Mer in G minor. The happy music piece was Granados's Allegro de Concierto in G major. To control the "happy" effect of major key, they also played the minor key pieces in major key, and vise versa. The researchers explained that sad music aroused contradictory emotions because the participants of the study tended to feel sad to be more tragic and less romantic than they felt themselves while listening to it. " In general, sad music causes sadness in listeners, and sadness is regarded as an unpleasant emotion. If sad music actually arouses only unpleasant emotion, we would not listen to it," the researchers wrote in the study. "Music that is believed as sad actually causes romantic emotion as well as sad emotion.And people, regardless of their musical training, experience this ambivalent emotion to listen to the sad music," added the researchers. Also, unlike sadness in daily life, sadness experienced through art actually feels pleasant, possibly because the latter does not cause an actual threat to our safety. This could help people to deal with their negative emotions in daily life, concluded the authors. "Emotion experienced by music has no direct danger or harm unlike the emotion experienced in everyday life. Therefore, we can even enjoy unpleasant emotion such as sadness. If we suffer from unpleasant emotion aroused through daily life, sad music might be helpful... Question: What is the main idea of this passage? Yes or no, is the answer "Sad music may actually cause positive emotions."?

Ans:
Yes
