Write a multi-choice question for the following article, with the given choices and answer: Article: A serious threat to farmers in many parts of the world is erosion. Erosion occurs if a large area of land is cleared of trees and is then badly treated by the farmers. The rain and winds may gradually wash away, or blow away, much of the topsoil. When this happens, crops of wheat or corn become weaker and weaker until nothing grows well. If erosion continues, it will turn good land into a desert. In the past, when erosion appeared, farmers sometimes moved to a new place to farm. Sometimes they could not move, but continued to try to grow food in the unhealthy soil. This caused them to sink into poverty. Soon some people realized that there was little rich, fertile soil in the world, government began to try to stop erosion. One of the first experiments to stop erosion began in the prefix = st1 /United Statesin 1933. The experiment was carried out in the area of the Tennessee River. Floods and had farming in this area had ruined land that had once been rich. As a result, most of the people living around the Tennessee River were very poor. The government built big dams across the river and stored the water for use during the dry season when there was no rain. The government workers also helped farmers to fertilize their soil and to learn new farming methods which could stop erosion. At the beginning, the farmers were not interested. But soon, good healthy crops began to appear on the land where new methods where used. Ten years after the extremely prosperous, the great success of this experiment had led similar projects in the other parts of the world. Options: A how erosion occurs B the importance of using new farming methods C something can be done to prevent erosion D the serious outcomes of erosion Answer: C something can be done to prevent erosion Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer? This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes -- clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended with flexible electronic materials to create intelligent clothing. The result are electronic garments. If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say. The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap- tap' gadgets are all set to take over laptop computers! Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim jacket with flexible earphones sewn into the hood and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids. Having completed the cloth keyboard, scientists have already started to work on a new project--a necktie that can be used as a computer mouse. What is the next? Do you have any idea? Options: A they feel smooth and soft B they use electricity as power C they can be washed in water D they are made from flexible materials Answer: B they use electricity as power Question:
A: . The electronic garments are similar to other electronic devices in that _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are. Researchers believe the images can reveal important information about a patient's health and even give them early warning of serious illness. A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle, which is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to learning about a person's physical health, or "zheng" according to Chinese medicine. "Within a year, our goal is to create an application for smart phones that will allow anyone to take a photo of their tongue and learn the status of their zheng," said Dong Xu, chair of MU's Computer Science Department in the College of Engineering and the co-author of the latest study. The software analyzes images based on the tongue's color and coating to distinguish between tongues showing signs of "hot" or "cold" zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng. "Hot and cold zheng doesn't refer directly to body temperature," said Xu, "Rather, it refers to a series of symptoms associated with the state of the body as a whole." For the study, 263 gastritis patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng. This allowed the researchers to test the accuracy of the software's analysis. "Our software is able to classify people based on their zheng status. And as we continue to work on the software we hope to improve its ability," said another co-author Ye Duan, "Eventually everyone will be able to use this tool at home using webcams or smart phone applications, which will allow them to monitor their zheng and... Options: A one's body temperature B the physical health of a person C the possible disease of a person D the color and coating of one's tongue Answer: B the physical health of a person Question:
Answer: According to Chinese medicine, zheng refers to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: MEGADIM, Israel (AP)-The worst forest fire in Israel's history on Thursday destroyed one of the country's few forested areas, killing at least 36 guards on their way to rescue prisoners there, destroying homes and forcing the evacuation of thousands. The fire ran through the Carmel forest in Israel's Galilee, reaching the coastal city of Haifa, jumping from place to place in the forest. The fire broke out around midday and quickly spread and was still burning out of control as midnight approached. Investigators supposed that the fire could have been set accidentally, or it might have been a criminal act, but pretty much ruled out some sort of attack by a Palestinian group. "This is a huge disaster," Prime Minister Benjamin Netanyahu said. "The government is using all means to control the fire." He said some countries such as Cyprus, Italy, Russia and Greece agreed to provide backup. Most of the dead were Prison Service guards racing through the fire toward a prison to evacuate the prisoners, most of them Palestinians. A tree fell across the road, blocking their bus. Some guards were burned alive inside, while others died as they tried to escape. Fourteen bodies were found near the burnt bus 10 hours after the fire started. The fire heavily damaged one of Israel's few large forests, made up of natural growth and planted areas, a favorite place for camping and a home for dozens of species of wildlife. Forestry workers tried to evacuate animals from the fire. The forest recovered slowly from a fire in 1989, but experts said Thursday's big fire was many times worse. Options: A all of the dead were Prison Service guards B the forest once suffered a fire in the 1980s C the animals didn't suffer from the fire D the fire caused 50 deaths altogether . Answer: B the forest once suffered a fire in the 1980s Question:
