Question: Problem: Write a multi-choice question for the following article: Article: Fish have ears. Really. They're quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths. As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate  . By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish's age, just like the growth rings of a tree. Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They're examining the chemical elements   of each otolith ring. The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring. Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history. In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles. This is important to managers in the fish industry, who know nearly nothing about the track of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears.

A: Question: Why is it important to study the chemistry of otolith rings?Options:A The elements of the otoliths can tell the history of the sea.B Chemical contents of otoliths can tell how fast fish can swim.C We can know more about fish and their living environment.D Scientists can know exactly how old a fish is.Answer:C


Problem: Write a multi-choice question for the following article: Article: One summer I was driving from my hometown of Tahoe City,Calif.,to New Orleans.In the middle of the desert, I came upon a young man standing by the roadside. He had his thumb out and held a gas can in his other hand. I drove right by him.There was a time in the country when you'd be considered a jerk if you passed by somebody in need. Now you are a fool for helping. With gangs, drug addicts, murderers, rapists, thieves lurking everywhere, "I don't want to get involved" has become a national motto. Several states later I was still thinking about the hitchhiker.Leaving him stranded in the desert did not bother me so much.What bothered me was how easily I had reached the decision.I never even lifted my foot off the accelerator. Does anyone stop any more? I wondered.I recalled Blanche DuBois's famous line:"I have always depended on the kindness of strangers". Could anyone rely on the kindness of strangers these days? One way to test this would be for a person to journey from coast to coast without any money, relying solely on the goodwill of his fellow Americans.What kind of Americans would he find? Who would feed him, shelter him,carry him down the road? The idea intrigued me. The week I turned 37,I realized that I had never taken a gamble in my life.So I decided to travel from the Pacific to the Atlantic without a penny.It would be a cashless journey through the land of the almighty dollar.I would only accept offers of rides, food and a place to rest my head.My final destination would be Cape Fear in North Carolina,a symbol of all the fears I'd have to conquer during the trip. I rose early on September 6, 1994, and headed for the Golden Gate Bridge with a 50pound pack on my back and a  sign displaying my destination to passing vehicles:"America". For six weeks I hitched 82 rides and covered 4,223 miles  across 14 states.As I traveled, folks were always warning me  about someplace else.In Montana they told me to watch out for  the cowboys in Wyoming; in Nebraska they said people would not  be as nice in Iowa. Yet...

A: Question: In the passage,the author described his journey as a gamble because   _  .Options:A he was not so sure of the outlook of the journeyB he had no money to give to strangersC he was sure of the coming sufferingsD he wasn't sure whether to make the journeyAnswer:A


Problem: Write a multi-choice question for the following article: Article: It is the preferred choice of millions of health-conscious Britons. But eating organic food   could make you fat, experts have warned. A studyhas shown that people tend to believe that organic foods contain fewer calories, so buy and eat more. But people who decide to "go organic" could soon find themselves piling on the pounds. The warning comes from American researchers who studied whether the sight of an organic label was enough to influence a person's choice. For example, if people believe organic foods, produced without using pesticides   and artificial fertilizers  , have fewer calories, they may end up eating far too much and spending less time on sports activities and put on weight. Cornell University researchers said: " Some people mistakenly think that these foods are more nutritious  , just because they carry an organic label." "The growing popularity of organic foods has led to some concern, as these foods may not necessarily be healthier than non-organic ones, but still may lead consumers to nutritional mis-judgments. If people feel a food to be more nutritious, they tend to let their guard down when it comes to counting calories---in the end leading them to overeat." Although a small number of differences in nutrient content were found to exist between organically-produced crops and traditionally-produced ones, these are of little health importance. It shows that there is no proof to support the choice of organically over traditionally-produced foods because of nutritional advantage.

A:
Answer: Question: Which of the following is TRUE?Options:A There is no evidence that organic foods have more nutrition.B Traditional foods are richer in nutrition.C Britons are wise in choosing organic foods.D Organic labels play a supporting role in shops.Answer:A
