Problem: Write a multi-choice question for the following article: Article: People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath. In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors can sort out these substances with increasing sensitivity . Scientists are building electronic sniffers that examine the exhaled air for signs of cancer, asthma , and other diseases. "There are clear signatures in the breath for liver disease, kidney disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease." said Dr. Raed Dweik, director of the Cleveland Clinic, adding "Breath analysis is the future of medical testing." He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations of the breath in graphics. Dr. Raed Dweik said, "If you examine patients of asthma, you will find they have higher levels of nitric oxide in their exhaled air. It reflects their abnormal symptoms in the lungs." His tests have reached 85 percent accuracy so far in spotting people with some illness. But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy--although without the ability to identify particular compounds the way some detectors can. "We are getting better and better," he said. "But whether we will ever approach the accuracy of the dog--we don't know."

A: Question: What is the breath detector used for?Options:A To find what kind of disease a person has.B To identify substances from people's breath.C To help a patient recover from disease.D To smell how bad the breath is.Answer:B

It is in the southern part of our country .It is really a very beautiful place-grand mountains, clean rivers and kind people. Trees and flowers are seen everywhere. Every year there are lots and lots of visitors. Maybe you have heard about Shi Lin (stone forests). There are all kinds of strange stones.

Of all the stones, the stone like a beautiful girl in a legend is the most famous .Its name is A Shima. I also went to Li Jiang. The roads in that city are just like the Eight Diagrams.

They are very cordial. And they all like singing and dancing. We danced with them around the campfire that night. I really had a good time. I like the elephants and fruits there best. An elephant is even taller than me! I even mounted the elephant, though I was very afraid at first. But the elephant seemed very friendly. I took some photos with it.

Problem: Write a multi-choice question for the following article: Article: There is no better way to enjoy Scottish traditions than going fishing and tasting a little bit of whisky at a quiet place like the Inverlochy Castle. When Queen Victoria visited the castle in 1873, she wrote in her diary, "I never saw a lovelier spot ," And she didn't even go fishing. Scotland is not easily defined. In certain moments, this quiet land of lakes and grasses and mountains changes before your very eyes. When evening gently sweeps the hillside into orange light, the rivers, teeming with fish, can turn into streams of gold . As you settle down with just a fishing pole and a basket on the bank of River Orchy, near the Inverlochy Castle , any frustration will float away as gently as the circling water. It's just you and purple, pink, white flowers, seeking a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime's fun. For many, fishing is more than a sport; it is an art. Scotland offers interesting place where you can rest after a long day's fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland's mountains. Ben Nevis is the highest of all British mountains, and reaching its 1343-metre top is a challenge. But it's not just what goes up matters; what comes down is unique. More than 900 metres high, on the mountain's north face, lies an all-important source of pure water. Its name comes from the Gaelic language "usquebaugh" or "water of life"; and it is the single most important ingredient in Scotland's best known drink: whisky.
