input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Just as they were getting ready to leave the street corner, they noticed a man walking toward them. He was obviously a wealthy man ---- they could tell that from the finely tailored business suit he was wearing and the gold watch chain that decorated his left pocket. The first beggar whispered to the second with excitement, "He's coming our way!" The two tried not to look directly at the man as he stepped closer to them, but they couldn't help glaring at him with expectation as he reached into his pocket and took something out. "Thunk" was the only sound they heard as what looked like a piece of hard candy, wrapped doubly in tissue paper, hit each of their waiting hats. The rich man turned and continued on his way, not making a backward glance. "How disgusting !" said the first beggar, as soon as the rich man was out of sound range. "He could have easily left us a few coins or a spare bill, but he tricks us with a piece of rock candy." He looked at the wrapped offering with disgust. "Who does he think we are ---- children? There's no way we can even eat this ---- we have no teeth." The beggar picked up the object with the very tips of his fingers and threw it into the gutter . He watched as it floated a few yards in the stream of smelly water and disappeared at the end of the street. Then, he gathered up his things and walked away. The second beggar looked down at the candy in his hat, then at his departing friend. His first impulse was to throw the donation in the trashcan under the street light. But his second thought made him change his mind. "I haven't had anything like this for ages," he thought. "I can't chew it, but I can suck on it for a while, and the sugary juices will stay in my mouth for a long time. How nice of that man to offer me something so sweet." He eagerly opened the paper outside, then paused as his hands touched the white tissue paper inside. "Maybe I should save it for another time," he thought. "It won't spoil, and I could eat it later when I'm really hungry." The beggar hesitated... Options: A Rich people who give offering to the poor deserve more respect. B Those who are lazy may miss more opportunities. C Things which have no attractive appearance may be more valuable. D Those who appreciate what they own are more likely to be rewarded. Answer: D Those who appreciate what they own are more likely to be rewarded. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: One baby born with a defective windpipe now has hope of breathing normally thanks to 3-D printing technology, NPR reported. Garrett Peterson, now 18 months old, was born with tracheomalacia , leaving him unable to breathe. The condition terrified his parents, who turned to specialist Dr. Glenn Green at the University of Michigan for a possible treatment. Along with Scott Hollister, a biomedical engineer who runs the university's 3-D printing lab, Green designed a device that can hold open Garrett's windpipe until it's strong enough to function independently. After taking a CT scan of Garrett's windpipe to make a replica of it, they made the "splint" with a 3-D printer. "It's like a protective shell that goes on the outside of the windpipe, and it allows the windpipe to be tacked to the inside of that shell to open it up directly," Green told NPR. On January 31, Garrett had his surgery. Surgeon Dr. Richard Ohye opened up Garrett's chest and saw that his windpipe had completely collapsed and one of his lungs was completely white -- a condition Ohye had only seen in dead bodies. After eight hours of surgery and careful placement of a splint on either side of Garrett's windpipe, it was time for the big test: What would happen when they let air flow through the windpipe into Garrett's lungs? Though he still remains in the hospital, Garrett has gotten stronger and needs less assistance breathing in the weeks since his surgery. His parents are overjoyed, saying he's starting to act more interactive and alert. As Garrett grows, the splint will expand and eventually dissolve in his body as his own windpipe strengthens enough to work independently. 3-D printing technology has allowed doctors to help patients in ways that they hope will continue to grow. "We're talking about taking something like dust and converting it into body parts," Green said. "And we're able to do things that were never possible before." Options: A The introduction of 3-D printing technology by medical workers. B The development of 3-D printing technology by engineers. C The use of 3-D printing technology in saving a baby. D The Potential of 3-D printing technology in surgery. Answer: C The use of 3-D printing technology in saving a baby. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Most American students have to say goodbye to fancy fruits these days. In school restaurants across the country, cheaper fruits like apples and oranges have taken their place. "People are afraid to spend now." said Linda Morrow, who owns a shoe and handbag store. "They don't know what the future will bring". During the financial crisis , several of the country's biggest banks have been forced to sell or close. This has made lots of Americans afraid to buy expensive things. The crisis began last year. Experts think it was because US banks lend money too easily. Last year a lot of people and companies, who borrowed money, found themselves unable to pay it back. This left the banks, as well as the people who put their money in the banks, without money. Since the banks borrowed money between themselves and even across borders , the whole world was in trouble. This month the US government agreed on a $700 billion plan to try to save the financial market. But no one is sure whether it will help or not. Last week presidents from 20 countries promised to work together to find a way out of the money trouble. Options: A when the financial crisis began B when the financial crisis will end C why some of the US banks closed D whether the crisis has spread to other countries Answer: B when the financial crisis will end Question:???
