Question: Write a multi-choice question for the following article: Article: Hong Kong is one of the most densely populated cities in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation for its light pollution. A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard. The crowded city of 7 million residents , full or residential high-rises, towering office blocks and neon advertisements, has no laws to control outdoor lightning. The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai. "In Hong Kong , you can't go anywhere outdoor in the evening without your eyes being blinded by this really disturbing outdoor lightning," the light pollution survey's head Jason Pum told AFP. "The fact that we have all this light in the sky means energy is wasted," he said, adding that too much artificial lightning also affects nightly wildlife. Research has suggested that light pollution can cause a number of harmful health effects in humans, including sleeplessness and headaches and can also interrupt body clocks and hormones . The university survey, the result of five million measurements taken from points across the city, was released just days before the start of the annual Earth Hour event, organized by the World Wildlife Fund. People around the world will be encouraged to turn off the lights for an hour on Saturday night to raise awareness of climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour. "Anyway, we should do our best to reduce the amount of lightning and adjust it for the benefit of the environment."

Question: Write a multi-choice question for the following article: Article: Spending just a few hours a week online may make people feel more socially isolated , lonely and downhearted , according to a two-year study of nearly 100 families with the Internet. "We were surprised to find that social technology has such bad effects on social communications," the lead author, Dr. Robert Kraut of Carnegie Mellon University in Pittsburgh, Pennsylvania, said in a statement to the news. The findings suggest that "Rather than encourage students to use the Internet alone for research, teachers might give pupils online group homework to complete with classmates. Local groups might build websites that allow neighbors to discuss local affairs ." "Before the technology develops and can be really more _ , people shouldcontrol their wishes to use much of the Internet," Dr. Kraut and other experts advise. In order to control their children and encourage family activities, parents might think of putting the computer in the living room rather than in a child's room, they suggest.

Question: Write a multi-choice question for the following article: Article: "Old wives' tales" are beliefs passed down from one generation to another. For example,most of us remember our parents' telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking,but others have not passed the test of time. Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic is good for you,too. It can kill the type of virus that causes colds. Unfortunately, not all of Mom's advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems?Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars. Even though science can tell us that some of our traditional beliefs don't _ there is still a lot of truth in the old wives' tales. After all, much of this knowledge has been accumulated from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.
