input: Please answer the following: Write a multi-choice question for the following article: Article: Different kinds of soil conservation methods are used by farmers to protect their land from damage by farming and the forces of nature. One important form of soil conservation is the use of windbreaks. Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant them in lines around their fields. Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat. There have been studies done on windbreaks in parts of West Africa, for example. They found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection. However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions will lift soil into the air where it will be blown away. For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line. There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for windbreaks.

Please answer this: Write a multi-choice question for the following article: Article: Dubai boasts that it has just built a "new global landmark"---the Dubai Tower, which stands 512.1 meters high now and has just become the tallest building in the world. The Dubai Tower now _ Taiwan's Taipei 101, which is 508 meters tall, and has 141 storeys, more than any other building in the world. The Dubai Tower, being built by South Korea's Samsung Corporation and scheduled for completion next year, is one of a series of great projects taking shape in Dubai. The final projected height of the tower has remained a secret since the project was launched in January 2004; however, it is rumored that the tower will be more than 700 meters tall and have more than 160 storeys. The Dubai Tower has become the tallest building in the world in just 1,276 days, leaving behind other tall buildings. The Dubai Tower will house 30,000 apartments in addition to the world's largest shopping mall. It is the centerpiece of the 20-billion-dollar venture. Another venture gradually emerging across the desert sands is Dubailand, a series of multi-billion-dollar projects claimed to be the Middle East's very own Orlando. Dubai also paid 100 million dollars to buy the Queen Elizabeth II, one of the world's superb cruise liners , which it plans to turn into a luxury floating hotel. Faced with decreasing oil wealth, the Western-oriented emirate has raced to turn itself into a business and leisure hub and it aims to more than double the number of tourists to 15 million by 2015.

Problem: Write a multi-choice question for the following article: Article: I told my friend Graham that I often cycle the two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, "You mean fortunately." He explained that I should be glad of the extra exercise that the hill provided. My attitude to the hill has now changed. I used to grumble as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally as I wend my way up the incline I console myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smug smile of satisfaction as I reach the top of the hill. Problems are there to be faced and overcome. Helen Keller was the first deaf and blind person to gain a University degree. Her activism and writing proved inspirational. She wrote, "Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved." One of the main determinants of success in life is our attitude towards _ . From time to time we all face hardships, problems, accidents, afflictions and difficulties. Some are of our making but many confront us through no fault of our own. Whilst we cannot choose the adversity we can choose our attitude towards it. The biographies of great people are littered with examples of how they took these kinds of steps to overcome the difficulties they faced. The common thread is that they did not become defeatist or depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.

A: Question: From Helen Keller's example we can infer that _ .Options:A Great people are born to be great and successfulB Life is hard and difficult so we have to give upC We cannot achieve anything with an easy lifeD Practice makes people successful and powerfulAnswer:C

input question: Write a multi-choice question for the following article: Article: Scientists who try to predict earthquakes have gotten some new helpers recently--animals. That's right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives. One task for scientists today is to learn exactly which types of animal behavior predict quakes. It's not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It's also difficult at times to tell the difference between normal animal restlessness and "earthquake nerves". A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach. A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes. A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began...???
