input: Please answer the following: Write a multi-choice question for the following article: Article: A wise man once said that the only thing necessary for the victory of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people. Day after day my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability. Accountability isn't hard to define. It means that every person is responsible for his or her actions and liable for their consequences. Of the many values that hold civilization together --- honesty, kindness, and so on --- accountability may be the most important of all. Without it, there can be no respect, no trust, no law --- and, ultimately, no society. My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people's behavior are far less effective than internal restraints such as guilt, shame and embarrassment. Fortunately there are still communities --- smaller towns, usually --- where schools maintain discipline and where parents hold up standards that declare: "In this family certain things are not tolerated --- they simply are not done!" Yet more and more, especially in our larger cities and suburbs, these inner restraints are loosening. Your typical robber has none. He considers your property his property; he takes what he wants, including your life if you annoy him. The main cause of this breakdown is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it's the criminal who is considered victimized: by his underprivileged upbringing, by the school that didn't teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn't provide a stable home. I don't believe it. Many others in equally disadvantaged...

Please answer this: Write a multi-choice question for the following article: Article: To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn't a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater. "Planting tress is one way, but it isn't that simple. It doesn't solve the basic issue of water resources," says Wu Bo, a professor. "We need to calculate how much water the trees will absorb, or else it could have a negative effect." Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields using flood irrigation and earns a good income for his family. Other farmers haven't stuck it out : about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return. Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight. "With enough water, this problem can be solved," Lu says. "We can plant trees and grass, and they will grow bigger. That will stop the desert." Experts say that farmers could switch to drip irrigation to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to "Save Water, Protect the Environment".

input question: Write a multi-choice question for the following article: Article: After we finished thirteen miles of hiking, we were tired and our muscles ached as we made our way back to New England. The car ride to the airport followed by a two-hour flight left our legs more worse condition than they were when we first came off the mountain we just climbed. When we heard that two seats in first class on our next flight were available for a bit higher price, we jumped at the opportunity. Our spirits lifted immediately. After all, flying first class was a new experience for us, and we would end our adventure in comfort and style. As we boarded the plane, we noticed that the stewardess was working non-stop to ensure the comfort of the first class passengers. She could not walk by a seat without receiving an order. How much she must love her job! She smiled kindly at each one while attending to their needs. As the stewardess walked by our seats near the end of the flight, I looked at her and said, "Thank you and I hope you have a great night." She stopped, bent down, looked at me and said, "Excuse me." I repeated my words and she smiled in a rather funny way, almost as if I had asked her a question that she did not know how to answer. After a few moments she returned to our seats. "I can tell you work with the public," she said. "Why do you think so?" I asked. She answered very quietly, "Because you are the only passenger here to say something nice to me tonight and I really appreciate your kindness." The sense of belonging to the elite group of people in first class disappeared as we heard her words. Our first class seats offered us more than a comfortable ride. We were reminded that without kindness, we would be flying in no class.???
