Write a multi-choice question for the following article, with the given choices and answer: Article: Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted. Though some of these things may seem impossible, they're closer to reality than you might think. The world of 3-D printing is coming to a store near you soon. The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD(computer aided design)file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want. There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs , we can soon be living longer thanks to 3-D printed technology. Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 (767,594 yuan) developing a "3-D pizza printer". It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless. Options: A What is 3-D printing? B A new technology-3-D printing. C How to use 3-D printing? D The development of 3-D printing. Answer: B A new technology-3-D printing. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: I was sure that I was to be killed. I became terribly nervous. I fumbled in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could barely get it to my lips. But I had no matches, they had taken those. I looked through the bars at the guard. He did not make eye contact with me. I called out to him "Have you got a light?" He looked at me, shrugged and came over to light my cigarette. As he came close and lit the match, his eyes unconsciously locked with mine. At that moment, I smiled. I don't know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. In any case, I smiled. In that instant, it was as though a spark jumped across the gap between our two hearts, our two human souls. I know he didn't want to, but my smile leaped through the bars and caused a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile. I kept smiling at him, now thinking of him as a person and not just a guard. "Do you have kids?" he asked. "Yes, here, here." I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes were filled with tears. I said that I feared that I'd never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the prison, quietly and by back routes, out of the town. There, at the edge of town, he released me. And without another word, he turned back toward the town. Options: A The guard freed him in the prison. B The man smiled to please the guard. C The guard set the man free with permission. D The man was surprised to be set free. Answer: D The man was surprised to be set free. Question:
A: What can we infer from the story?

Write a multi-choice question for the following article, with the given choices and answer: Article: Hollywood is on the edge of a nervous breakdown. Worried about an industry wide writers' strike, struck by a series of theater-chain bankruptcies , burdened with unreasonable corporate profit, requirements and seemingly incapable of producing consistently creative movies, the American film industry is in a period of soul-searching. There's little doubt it will survive this crisis. But most insiders agree there is disease at both ends of the business--where film are produced, and where they're shown---that may take years to overcome. While annual box-office income increases for nine straight years, largely due to increased ticket prices, the number of actual tickets sold declined for the second year in a row. The construction boom has added nearly 10,000 theaters(more than 200,000 more seats) in the last five years. But due to a static audience base, eight major chains have gone into bankruptcy and several others are in terrible financial situations. In fact, insiders say, Hollywood is now in a business it does not want to be in. "There's a general problem in that the companies that have the most consistent output of material are least interested in what they're making," says former 20thCentury Fox CEO, Bill. And, Bill adds, "We're in a period where movies are getting bigger and more costly and less interesting and fulfilling to an audience." Today the studios are under the stress to increase profit margins for their corporate parents, and profit margins are hard to control in a business whose products are seen as impulse buys . Other business can increase profits by cutting costs--buying cheaper material, or making the candy bar smaller. Not Hollywood. "What we're cutting is risk," says the head of one major studio, who asked not to be named, "And risk is what great film has always demanded." While the studios are avoiding risky concepts, their competitors in the home entertainment business have been expanding the boundaries of the imagination. It was this pressure---in electronic games, the Internet,... Options: A Hollywood will survive financial crisis B Hollywood is on the edge of destruction C It's hard to increase the profits of the studios D The construction boom leads to theater-chain bankruptcies Answer: B Hollywood is on the edge of destruction Question:
