Write a multi-choice question for the following article: Article: I have been very lucky to have won the Nobel Prize twice. It is, of course, very exciting to have such an important recognition of my work, but the real pleasure was in the work itself. Scientific research is like an exploration of a voyage of discovery. You are continually trying out new things that have not been done before. Many of them will lead nowhere and you have to try something different, but sometimes an experiment does work and tells you something new and that is really exciting. However small the new finding may be, it is great to think " I am the only person who knows this" and then you will have the fun of thinking what this finding will lead to and deciding what will be the next experiment. One of the best things about scientific research is that you are always doing something different and it is never boring. There are good times when things go well and bad times when they don't. Some people get discouraged at the difficult times but when I have a failure, my policy has always been not to worry but to start planning the next experiment, which is always fun. It is very exciting to make a new discovery. Some people will do the strangest things for this excitement, such as going round the world in a balloon or walking to the North Pole. There are not many new places to explore but there is a lot of new information to be discovered in science and a journey into this unknown area can be much more worthwhile and just as exciting. I am sometimes asked, "What do you have to do to win a Nobel Prize?" My answer is: "I don't know. I have never tried." But I know of one way not to win one. There are some people whose main reason for doing science is to win prizes and they are always thinking about how to do it. Such people don't succeed. To do good science you must be interested in it and enjoy doing experiments and thinking out problems. And, of course, you must be prepared to work hard and not to be too discouraged by failure.

Write a multi-choice question for the following article: Article: Most people know precious gemstones by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It's more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone's origin. Beneath the surface of a gemstone, on the tiny level of atoms and molecules , lie clues to its origin. At this year's meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers to clarify these clues and identify a stone's homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. "With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from," McManus told Science News. Some gemstones, including many diamonds, come from war-torn countries. Sales of those "blood minerals" may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones. To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles called electrons separate from atoms. The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area...
Ans: Question: Why did the U.S. government pass law that requires companies selling gemstones to determine the origins of their stones?Options:A To look for more gemstones.B To encourage violent civil wars.C To reduce the trade in blood minerals.D To develop the economy.Answer:C

Write a multi-choice question for the following article: Article: One day he is a famous policeman. The next day he is a gangster from Temple street. His songs are heard on radios all over Hong Kong. This is Andy Lau Tak Wah, the superstar that everyone sees, hears and loves. He is one of the most famous actors and singers in Hong Kong. However, there is another side to Andy Lau. There is an important part of his life that only a few people know about. Andy Lau helps 15 children from poor countries all over the world. These boys and girls live in 11 different countries. Most of the children have not met him and none of them know that he is one of the biggest stars in Asia. Andy Lau's interest in children started when he did some work with World Vision. This is a charity that helps poor children to lead better lives. For $200 a month, a _ helps with the food and education of one child. The child does not receive the money in cash. Instead the money pays for the child's school fees, food, medical care and clothing. Each child knows the name of the sponsor who is giving the money. The sponsor receives a report each year on the child's progress. They can write to each other, but usually the children do not speak Cantonese or English. When Andy Lau heard about these children, he wanted to help them. "It was not anything special," he said. "Until I had the chance to go to Indonesia and meet the little girl I am sponsoring, I didn't know anything about the type of life she had." He said the meeting with Nina in Indonesia was very emotional. "When I met her, I felt very, very happy," he said. "I saw that the money was used for a very good purpose. It brought me closer to the child in a way that simply giving money cannot." By sponsoring these children through a charitable organization, Andy Lau is giving them hope and at the same time caring for them. "I want to do whatever I can. I will continue to help these children in need," he said.
Ans: Question: The children that Andy Lau helps do not _ .Options:A go to schoolB want to meet himC know he is famousD have any foodAnswer:C
