I'm taking a test and have to guess the right answer to the question after the article. Article: A small piece of fish each day may keep the heart doctor away. That's the finding of an extensive study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed  at least an ounce of salt water fish per day than those who never ate fish. The Dutch research is one of three human studies that give strong scientific backing to the long-held belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States , with more than 550, 000 deaths occurring from heart attacks each year . But researchers previously have noticed that the incidence  of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces. During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age , high blood pressure , or blood cholesterol   levels . Question: The passage is mainly about   _  . Options: A: the high incidence of heart disease in some countries B: the changes in people's diet in the United States C: the daily fish consumption of people in different cultures D: the effect of fish eating regularly on people's health

I'm taking a test and have to guess the right answer to the question after the article. Article: Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door. They believe the 220- kilogram brown bear probably learned the trick while nudging   a door to get it to open. Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick. The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door. ''We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time." Mum Nevenka Loknar told a reporter from a local newspaper. "I opened the door and saw him standing there and I didn't believe my eyes at first, then I ran for it as he walked in as if _ was the most normal- thing in the world." Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door. Mum Nevenka Loknar said, "The bear is so intelligent. It's incredible. We've tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn't be surprised if he knew how to use wire cutters." Question: According to experts in Croatia, how did the bear learn the trick? Options: A: By knocking at the door several times. B: By accident. C: By learning from the owner of a family. D: By imitation.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: "Indeed," George Washington wrote in his diary in 1785, " some kind of fly, or bug, had begun to eat the leaves before I left home. " But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century,and Americans had already created lightning-bug .But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries. The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like. Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug,that is,"to install an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversations. Since the 1840s,to bug has long meant" to cheat" , and since the 1940s it has been annoying. We also know the bug as a _ in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as"little problems and difficulties" that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison" had been up the two previous nights discovering' a bug' in his invented record player." Question: The passage is mainly concerned with  _  . Options: A: the misunderstanding of the word bug B: the development of the word bug C: the public views of the word bug D: the special characteristics of the word bug

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: In a world today of immense technology, population growth and economic flourish, planning for future residential   and commercial developments needs careful analysis with well thought through assumptions about effects on the environment and the people of the community. One example of a growing city is Wooster, Ohio, my place of residency, Wooster in the last five years has grown considerably in population, leading to a growth in commercial business. Surrounded by farmland, Wooster's planning commission chose to extend the community into these farm areas in the form of residential and commercial areas. Picture this--corn fields, old trees, clean air, country roads, and wildlife are all part of the area. Within four years, the people living on this farm step outside on their front porch to view an extensive shopping center containing Wal-Mart, McDonald's, Wendy's, TCBY, and a Cinemark movie theatre. The once quiet road is now a city street with traffic lights, busy with automobiles day and night. The air smells of car exhaust and fast food. Some destruction of farmland is unavoidable when a city expands. Instead of expanding outward, planning commissions should consider interior  _ of a city. Tearing down unusable buildings could remodel many areas inside the city. In addition, commercialized buildings could extend upwards to avoid unnecessary use of land. Environmentally, commercial expansion is harmful to the land. Besides forms of pollution, wildlife, including both plants and animals, is put at risk. A planning commission could have realized the benefits of environmental protection. Why not preserve the beauty and naturalness of the land while at the same time allowing for growth? With a steady growth of population and the need for more homes and more workplaces, many problems arise when planning for the future. The hillsides, fields and animal habitats need to be preserved while expanding cities. In the future, a world covered with concrete and asphalt could become reality. Serious research and analysis...
