Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Wikipedia is a free-access, free content Internet encyclopedia , supported and hosted by the non-profit Wikipedia Foundation. Wikipedia is ranked among the ten most popular websites and is considered the Internet's largest and most popular general reference book. Now, Wikipedia is becoming Wookiepedia as scientists hope the informative website will help us reach out to intelligent life forms. So aliens can learn about the human race. Astronomers would like to beam the entire contents of Wikipedia into space in the hope of contacting aliens. They want to send messages to hundreds of star systems and planets 20 light years away using radio telescopes. The Search for Extraterrestrial Intelligence Institute, in California, wants to use powerful radio telescopes to try to reach Chewbacca and his mates in a galaxy far away. The plans will be discussed by astronomers at the weekend as some scientists fear the reply from ET might not turn out to be friendly. Institute scientist David Black said, "One question is if there are dangerous creatures we might be drawing their attention to ourselves. Another is if we go ahead, what message should be sent? There could be many civilizations out there,but if they are all listening and no one is broadcasting or responding, then nothing will happen." Professor Stephen Hawking, who has warned that intelligent aliens probably exist and we should keep a safe distance from them, is among _ . "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. Signals from Earth's radio and TV broadcasts have been heading out in space for some 60 years reaching around 5,000 stars. Options: A intelligent aliens would probably land in America. B the plans will be in vain and nothing will happen. C none of the civilizations would reply. D aliens would bring disasters to the human race. Answer: D aliens would bring disasters to the human race. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: The time children spend outdoors could be linked to a reduced risk of being short-sighted, research suggests. An analysis of eight previous studies by University of Cambridge researchers found that for each additional hour spent outside per week, the risk of short-sightedness was reduced by 2%.They said exposure to natural light and time spent looking at distant objects could be key factors . The studies involved more than 10,000 children and adolescents. Dr Justin Sherwin and his research team concluded that short-sighted children spent an average of 3.7 fewer hours per week outdoors than those who either had normal vision or were far-sighted. But they said the reasons were not yet clear.They expected to find that children who spent more time outdoors also spent less time doing activities like reading, studying or playing computer games, but no such link was found in two of the eight studies which looked at this relationship. However, Dr Sherwin said they would now need more precise data to try to understand which factors, such as increased use of distance vision, reduced use of near vision, natural ultraviolet light exposure and physical activity,are most important. "Any increase in time spent outdoors must be weighed against exposure to ultraviolet radiation and the increased risk of skin cancer, cataracts and other cancers."he said."On the other hand, increasing outdoor physical activity could protect against diabetes and obesity, for example." Short-sightedness is a common eye condition that causes distant objects to appear blurred , while close objects can be seen clearly. It is much more common today in the UK and the United States than it was just 30 to 40 years ago. Approximately 1-2% of five-year-olds to seven-year-olds in the UK have short-sightedness.About.five million British people are short-sighted and some 200,000 of them will be seriously short-sighted. In some parts of Asia, more than 80% of the population suffers from short-sightedness. Options: A obesity B exposure to natural light C looking at distant objects D time spent outdoors Answer: A obesity Question:
