Write a multi-choice question for the following article, with the given choices and answer: Article: When Rikke Dausen in prefix = st1 /Denmarkgoes to get some milk from the fridge, she has trouble getting past the refrigerator door. But it's not because of any physical obstruction. It's usually because the PC monitor in her refrigerator's door has informed her that a new email message has arrived. Rikke and her husband are taking part in a six-month trial sponsored by a Danish firm and two Swedish partners. They hope to show that computers can be put to much more practical daily use than most people think. Fifty families and singles were provided with a free model known as the "Screenfridge" for the duration of trial. "It's really very clever", says Rikke. She can call up email, news reports, sales items at the supermarket or addressed out of the endless ocean Internet possibilities. "I'm not the type who wants to sit in front of the computer and wait 10 minutes for the modem to connect," she says. The creators of the Screenfridge aim at this type of buyer. They think the machine should attract people who have limited time to solve technical problems or surf online. The PC that is built into the door is very small. It is only two centimeters wide, and completely silent. "Everything moves quickly", as Rikke admits. "Well, the whole thing is really just an amusement", she says. "But when the thing is gone after the test, it will be pain to have to go down in the basement again to download my email". The Screenfridge is due to hit the market sometime next year. Options: A Several months. B More than a year. C Several years. D Several hours. Answer: A Several months. Question:
----
Answer: How long has Rikke probably been using the Screenfridge?

Write a multi-choice question for the following article, with the given choices and answer: Article: When people imagine a classroom, they usually think of older people teaching younger ones. But when it comes to learning about high-technology devices, the opposite can often be true. A training program called the 50 Plus Center in the eastern American city of Columbia, Maryland offers free technology classes to adults over 50. The training program also offers many other kinds of lectures from Qigong and Tai Chi to yoga and Latin jam dance. There are a lot of exercise programs including playing cards and physical exercises where many people just relax and spend some time together. Myra Stafford is 73 years old. She signed up for the class to learn how to use her iPad. She is learning quickly with the help of the young and she enjoys learning from them. She says she is more confident today than she was before. Working with young people makes her feel wonderful because they don't make her feel that she is old or dumb. Eleven-year-old Zhion Perekins is a teacher of the technology class. He says some of the older adults know nothing about high-technology devices and they are very anxious, so patience is very important when working with them. He gains more than just social skills from teaching older residents. He has learned a lot on how to communicate with people. He used to be a shy person, but now he has become outgoing. There is a huge growing population over 60. The training program offers an opportunity for the old people to buy products online using high-technology devices. As senior citizens get more excited about what they want to buy, it is likely that they will go into the market and buy it, so that could lead to an increase in economy. Options: A Myra Stafford is not satisfied with the classes. B The training program may do good to economy. C Myra Stafford is too old to learn technology well. D More and more senior citizens will attend the classes. Answer: B The training program may do good to economy. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Two-thirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to stole water and provide power. In the US,there are more than 85,000 dams,disrupting large and small rives, and in most cases transforming natural flow.The most famous of these,the Hoover Dam, constructed in the l930's,is mainly responsible for the fact that the Colorado River no longer reaches the ocean. Dams, besides all their attractive benefits, also have negative impacts. Creating a reservoir means a large area must be flooded. Communities may lose their land, houses and culturally impotent sites. Environmentally, the new reservoir can be a paradise for wildlife, especially birds. However, it can cause greenhouse gas emissions and poison the water for fish. Also, the dramatic rise and fall of water levels during dam releases is too extreme for plains and animals to cope with, resulting in dead zones around the shores of reservoirs. Fish that lay their eggs in the shallows, for example, may find a few hours later that those sites are high and dry. Dams don't just block water flow. They also prevent fish migrations, and are a barrier to sediment flows. Instead of rushing downriver, sediments get backed up against the dam wall, which cause the reservoir level to increase over time.However, sediments which are rich in nutrients have become a problem. The fertility of the entire system can be influenced, with soils lost during seasonal rains not being replaced. Perhaps the biggest problem can be seen in deltas , often host to large cities,which are sinking into the oceans. Groundwater is being extracted to feed the city, causing the urban weight to sink and sediments washed away by the ocean are no longer being replaced. The result is that sea level rise in cities from Shanghai to Alexandria. Options: A Its entire system will be influenced. B It will lie below sea level in the future C The rainy season will last longer. D Rich soils will be washed away Answer: B It will lie below sea level in the future Question:
