input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Is there a nationwide shortage of nurses? It's hard to say. However, some characteristic symptoms often indicate that there is indeed a shortage. One symptom is the vacancy rate, or the percentage of budgeted positions that are unfilled. New England's hospitals currently report that an average of 7 to 12 percent of their registered nurse positions are vacant, the highest level since the last shortage in the late 1980s. Vermont has a ly low vacancy rate, at 7.8 percent. But its vacancies were at 1.2 percent just five years ago. Another symptom is the increased use of stopgap measures to fill empty positions. For instance, many nurses report an _ in how frequently they are asked to stay past their shifts. According to Murphy, working in the St. Elizabeth's Hospital, "The shortage has definitely created a lot of opportunities of overtime for our nurses, whether they want them or not." Similarly, a national survey of registered nurses shows that in an average week, nurses in the U.S. work 2.4 more hours than they are scheduled to. Much of this extra time is voluntary, as nurses earn overtime pay when they stay to fill in blanks in the schedule. When they can't fill open positions by more traditional means, health care providers hire temporary staff to tide them over. Travelling workers are the largest part of the temporary health care workforce, hired for thirteen-week reduction at health care facilities facing short-term lack of workers. Temporary workers, mainly nurses, cost hospitals $ 7.2 billion in 2000. "Any successful solution to the shortage depends on convincing more people to become nurses, and that is not an easy goal to reach. To achieve it," says Buerhaus, "society needs to place more value on nursing. Legislation can't do that - it should come from people." And if this continues, we might have to learn to care for ourselves in the hospital. Options: A cost a large part of the hospital's budget B meet the need for nurses in the hospital for a short time C should work on a weekly basis and on a scheduled timetable D ought to work passively for thirty continuous weeks Answer: B meet the need for nurses in the hospital for a short time Question:???
output answer: The temporary staff hired by a hospital _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Step into an American preschool classroom today and you are likely to fall into a so-called print-rich environment,every surface colorfully decorated with instructional posters,classroom rules,chedules,and mottos,few of which a 4-year-old can understand in fact. Besides the confusing things on classroom walls,teaching methods and curriculums have changed recently,by which more time is spent on what's called "seat work"workbooks and worksheets--but less time devoted to music and art.School--readiness skills are essential for the youngest learners to move on to a subsequent stage. As a result, expectations that may arguably have been reasonable for 5-and 6-year-olds, such as bemg able to sit at a desk and using pencil and paper,are now directed at even younger children, who lack the motor skills and attention span to be successful. However,parents of preschoolers tend to _ these changes,because they fear that the old--fashioned pleasures of unhurried learning have no place in today's highly competitive world.The stress is obvious:Pick the "wrong" preschool and your child might not go to college.She might not be employable. She might not even be allowed to start first grade! As preschoolers are learning so much academic knowledge at earlier ages,they seem somehow less curious and less engaged.Some teachers say that more children today seem to lack the language skills.The real focus in the preschool years should not be just on vocabularv and reading,but on talking and listening.By talking with adults, and one another,they pick up information,learn how things work and solve puzzles that trouble them.For our littlest learners,what could be more important than that? Options: A Because some preschools are too old fashioned. B Because a wrong preschool might ruin kids' future. C Because the competitions between kindergartens are fierce. D Because it is easy for them to choose a right preschool. Answer: B Because a wrong preschool might ruin kids' future. Question:???
output answer: Why are parents so picky when choosing a preschool for their kids?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Humans: It's time to abandon the earth or face extinction. This prediction isn't science fiction. It's a glimpse of the future, according to famed British scientist Stephen Hawking. "I see great dangers for the human race," he said in an interview with global forum Big Think. "There have been a number of times in the past when its survival has been a question of touch and go ." Hawking says humans must _ our home planet within the next two centuries and expand into space to survive. "I believe that the long-term future of the human race must be in space," he said. "It will be difficult to avoid disaster on our planet Earth in the next hundred years, let alone the next thousand, or million." He also voiced some concerns about the future of life on the earth. In April, he spoke about his fear of aliens in an interview for the Discovery Channel. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said. "Such advanced aliens would perhaps become wanderers, looking to conquer and colonize whatever planets they can reach." But Hawking says he is still hopeful for the future of humanity. "I'm an optimist," he told Big Think. "We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space." Getting to another planet will prove a challenge, not to mention colonizing it for humanity. University of Michigan astrophysicist Katherine Freese told Big Think that "the nearest star to Earth is Proxima Centauri which is 4.2 light years away. That means, if you were traveling at the speed of light the whole time, it would take 4.2 years to get there" --- or about 50,000 years using current rocket science. Options: A About 4.2 years. B About 50,000 years. C Less than 42,000 years. D Over 10 years. Answer: B About 50,000 years. Question:???
output answer:
How long will it take to reach Proxima Centauri by current rocket?
