input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The saying that children don't like reading any more has been proved untrue. A new study finds that 75 percent of kids between five and 17 say that although they love technology, they still want to read books. The Kids & Family Reading Report also says that 62 percent of kids prefer reading printed books rather than those on a computer.At the same time, those who search an author's website or use the Internet to find books by a particular author, are more likely to read books for fun every day. The study also once again proves that the time kids spend reading books for fun decreases after the age of eight and continues to drop through the teen years.The report is a follow-up to a 2006 study.But this time the focus is on the role of technology and when kids' interest in reading starts to drop. "Despite the fact that after the age of eight more children go online daily than read for fun daily, high frequency Internet users are more likely to read books for fun every day," says Heather Carter, a writer of the report. One in four kids between five and 17 say they read books for fun every day and more than half of kids say they read books for fun at least two to three times a week.One of the key reasons kids say they don't read more often is that they have trouble finding books they like - a requirement that parents underestimate . The study also finds that parents have a strong influence on kids' reading, but only about half of all parents begin reading to their kids before their first birthday.The percent of children who are read to every day drops from 38 percent among five-to eight-year-olds to 23 percent among nine-to 11-year-olds - exactly the same time that kids' daily reading for fun starts to drop. "Parents' engagement in their child's reading from birth all the way through the teen years can have a great influence on how often their children read and how much they enjoy reading," adds Carter. Options: A Children don't like reading any more after the age of 8. B Most children like reading as well as going online. C All kids like reading e - books instead of printed ones. D Most children like going online instead of reading. Answer: B Most children like reading as well as going online. Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer -- migrating birds fly in a "V" to save energy, according to a study published in the journal Nature. When a bird flaps its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost from the rising air and therefore use less energy to stay in the air. Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward. "They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC. In fact, the "V" formation has long thought to help birds fly more efficiently . A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof. "For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies -- helping them understand how they can _ that with their plane formations to save fuel, said Portugal." Options: A It might inspire aircraft companies to think of ways to improve efficiency. B It has proved that the "V" formation can improve in efficiency in many fields, C It has led scientists to discover that birds' heart rates go down when they fly in a "V". D It shows that the best formation of jet fighters in battle should be a "V" formation. Answer: A It might inspire aircraft companies to think of ways to improve efficiency. Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: I'm perfectly aware that many people you know probably think you re crazy for wanting to travel instead of settling into a typical 9-5 lifestyle. It's difficult for others to understand your goals. Well, 1 certainly don't think you're crazy. In fact, every traveler I know would agree that you're only crazy if you decide not to go after your goals in life. I started traveling back in 1999, shortly after graduating from university. My plan was to backpack around Southeast Asia for three months and then return to the US to become a sports agent. However, just one week into that trip, I realized that tbree months of travel simply wasn't enough. The only problem was that I had less than $1,500 to my name. Fast forward lo today... Over the past 15 years, 1 have discovered, and taken advantage of, endless opportunities that have allowed me to continuously live, travel, study and earn money in over 85 countries. The point is, if I can make it happen with $1,500 and no idea what I was doing, you can make it happen as well. And with the knowledge and experience I'm about to pass on to you in this guide , you're going to have a much easier path ahead than I ever did! If you are constantly wondering how you can possibly achieve all of your travel goals during this lifetime, I just want to repeat everything you, re dreaming about really can be achieved. It'll take some haixl work and determination for sure, but when you find yourself living or traveling or working overseas, enjoying rewarding experiences, you'11 be thankful that you decided to choose a life of travel. And I honestly can't wait to meet up with you in some foreign land where we can swap travel stories over a beer or coffee or tea! Options: A Lack of experience. B Lack of money. C Lack of confidence* D Lack of encouragement. Answer: B Lack of money. Question:
