Article: A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds. The machine squirts out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers immediately they come to the market. Britain's biggest chocolatiers Thornton's have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype last year and has only just perfected it so that it can now go on sale. "We've improved and simplified the machine, so now it is really easy to use," he told the BBC. "You just need to melt some chocolate, fill a syringe that is stored in the printer, and get creative printing of your chocolate." 3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, "What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child's favourite toy to a friend's face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we've started with chocolate as it is easily available, low cost and harmless." "There is also no wastage as any spoilage can be eaten." Dr Hao added, "Eventually we may see many mass-produced products replaced by unique designs created by the customer."[:] EPSRC chief... Question: Dave Delpy's attitude towards the chocolate printer is _ . Yes or no, is the answer "supportive"?

Article: Human beings have a natural desire to explore the unknown. People with a strong interest in space like to say it is the last place left to explore. But scientists are warning that space exploration for long periods is not going to be easy. They say the human body is not designed to stay in space over an extended period. The New York Times recently published a report about scientists who are preparing astronauts for a trip to the Moon. The newspaper said the scientists want to make sure that their crews return home in good health. But there are many problems to be solved before people are ready for long trips to the Moon, an asteroid or even the planet Mars. Humans developed on a planet with a surface that is more than 70 percent water. Our bodies are also about 70 percent water. When there is no gravity that water moves up toward the head, raising pressure in the skull. Arms and legs grow weaker at what is called zero gravity because they no longer need to push against the force of gravity. Five years ago, astronauts who spent weeks in space reported a change in their eyesight. These astronauts were members of the crew on the International Space Station. Research showed a change in the shape of their eyes. Normally-round eyeballs had become flat during time in space. The research also showed that the right eye was affected more than the left, and that men were more affected than women. Scientists could not find an explanation for the differences. Bone loss was one of the problems first reported by astronauts returning to Earth after longer stays in space. So scientists designed exercise machines to use on the space station. Tests showed that the exercise equipment helped space travelers keep their bones almost as strong as when they left Earth. There are other health issues for astronauts who spend a long time in space. They may have problems eating and sleeping. But the biggest health issue is exposure to radiation. On Earth, human beings are protected by the atmosphere and the planet's magnetic field. In... Question: Why did scientists design exercise machines to use on the space station? Yes or no, is the answer "To help astronauts keep their bones almost as strong as when they left Earth."?

No

Ques: Article: Make Up Your Mind to Succeed Kind-hearted parents have unknowingly left their children defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and performance were played down because "everyone's winner." And their report cards sounded more positive than ever before. As a result, Stanford University professor Carol Dweck, PhD, calls them "the overpraised generation." Dweck has been studying how people deal with failure for 40 years. Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it. Here's how they work: A fixed mind-set is grounded in the belief that talent is genetic - you're a born artist, point guard, or numbers person. The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame. When things get difficult, it's quick to blame, lie, and even stay away from future difficulties. On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego isn't on the line as much, the growth mind-set sees failure as a chance rather than shame. When faced with a difficulty, it's quick to rethink, change and try again. In fact, it enjoys this experience. We are all born with growth mind-sets. (Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise. Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure. Question: What does the growth mind-set believe? Yes or no, is the answer "Getting over difficulties is enjoyable."?
Ans: No

Article: A ship was damaged during a storm at sea and only two of the men aboard were able to swim to a small island. Not knowing what else to do, the two survivors decided that they should pray to God. However, to find out whose prayers were more powerful, they agreed to divide the land between them and stay on opposite sides of the island. The first thing they prayed for was food. The next morning, the first man saw a tree on his side of the island, and he was able to eat its fruit. But the other man's side of land remained _ After a week, the first man became lonely and decided to pray for a wife. The next day, another ship was damaged and the only survivor was a woman who swam to his side of the island. But on the other side of the island, there was nothing. Soon the first man prayed for a house, clothes and more food. The next day, like magic, all of these things were given to him. However, the second man still had nothing. Finally, the first man prayed for a ship so that he and his wife could leave the island, and in the morning he found a ship stopped at his side of the island. The first man boarded the ship with his wife and decided to leave the second man on the island. As the ship was about to leave, the first man heard a voice from Heaven, "Why are you leaving your partner on the island?" "My blessings are mine alone since I was the one who prayed for them." The first man answered. " His prayers were all unanswered so he doesn't deserve anything." "You are mistaken!" the voice said. "He had only one prayer, which I answered. He prayed that all your prayers would be answered." Question: What does the author try to express through the story? Yes or no, is the answer "What we do for others is more important than what we do for ourselves"?
