Problem: Given the question: Write a multi-choice question for the following article: Article: Cellphones: is there a cancer link? Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cellphones can cause brain tumors. "It's apparent now that there's a real risk," said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cellphones," said Linet. "We don't have the evidence that there's much danger." Studies so far suggest a weak connection between EMFs and illness -- so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been _ for several years. It's funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cellphone use and cancer risk.

Problem: Given the question: Write a multi-choice question for the following article: Article: My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: "What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?" He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation is incredible . We're on a more different curve than we used to be. One thing I'm looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you'll be able to sample things before you buy them. But the question will be how I find what I'm looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded , with whom I might really want to communicate? I want to find those people but it's hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It's going to be very interesting, I think.

Problem: Given the question: Write a multi-choice question for the following article: Article: Sports can help you keep fit and get in touch with nature.However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment. Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water.Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses in good condition.This causes major environmental effects.For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas. There are many environment-friendly sports. Power walking is one of them that you can take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse.Simple and free, power walking can also keep you fit.If you walk regularly, it will be good for your heart and bones.Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control. Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials.But the final goal should be "green gyms".They are better replacements for traditional health clubs and modern sports centers.Members of green gyms play sports outdoors, in the countryside or other open spaces.There is no special requirement for you to start your membership.And best of all, it's free.
