Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Bobby was sitting out in his back yard in the snow. The thin sneakers he wore had a few holes in them. Try as he might, he could not come up with an idea for his mother's Christmas gift. Ever since his father had passed away three years ago, his mother worked nights at the hospital, but the small wage could only be stretched so far. What the family lacked in money and material things, they more than made up for in love and family unity. They ran the household in their mother's absence. All three of his sisters had already made beautiful gifts for their mother. It was Christmas Eve already, and he had nothing. Bobby started to walk down to the street. He walked from shop to shop. Everything seemed so beautiful and so out of reach. It was starting to get dark, then suddenly his eyes caught a shiny dime. Never has anyone felt so wealthy as Bobby did at that moment. He went inside a flower shop. When the owner asked if he could help him, Bobby presented the dime and asked if he could buy one flower. The shop owner looked at Bobby, then said, "You just wait here and I'll see what I can do for you." The shop owner returned holding red roses all tied together with a big silver bow. Bobby's heart sank as the owner placed them gently into a long white box. "That will be ten cents, young man," said the shop owner, reaching out his hand for the dime. Slowly, Bobby moved his hand to give the man his dime. Then the shopkeeper's wife appeared. "Where are the roses you were fixing?" The shop owner replied, "A strange thing happened to me this morning. I thought I heard a voice telling me to set aside a dozen of my best roses for a special gift. I wasn't sure at the time whether I had lost my mind or what, but I set them aside anyway. When I saw that little boy tonight, I knew who that voice was." Options: A Because he didn't know what to do. B Because he wanted to try his luck there. C Because he wanted to get some money. D Because he hoped to see what he could get. Answer: A Because he didn't know what to do. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: More than half of the world's population live in cities. Traffic and pollution are becoming big problems in big cities all over the world. In cities like Mexico City, Shanghai or Cairo the quality of air is getting worse every day. In the United States, people spend more time sitting in traffic jams. Some of the world's cities have already found the answer to the problem. In Bogota, the capital of Columbia, the government has taken measures to improve the quality of life for the city's 8 million people. They created over a thousand new parks, a new public transport system, and built hundreds of cycling and walking paths. People who live in the city also joined in making their city one of the most livable places in South America. Today city planners around the world are looking for ways to provide more room for living and less room for cars. In America, public transport has increased over 2 % since the mid 1990s -- not much but a start. More and more people leave their cars at home and get on buses, trains or even ride a bike to work. Some cities are far better at planning than others. In Amsterdam, for example, only 40 % of the population use their cars to get to work, 35 % ride bikes while 25% use public transport. In Paris, about half of the city's workers drive their cars to work. For cities in developing countries, the problems have just started. Traffic is getting worse as more and more people can afford to buy a car. Options: A heavy traffic B air pollution C rapid development D large population Answer: B air pollution Question:

A: The writer listed Mexico City, Shanghai and Cairo as examples of cities of _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Starting next month, people in prefix = st1 /Washingtonwill be able to rent a bicycle day and night with a membership card. A new company called SmartBike will make 120 bicycles available at 10 spots in the city. "There's a lot of stress on our transit systems," said Jim Sebastian, who manages bicycle and pedestrian programs forWashington's Transportation Department. Offering another choice, Mr Sebastian said, "It will help us reduce traffic jam and pollution, as well as parking problems." In the deal, the company will have the advertising rights in the city's bus shelters and it has reached a similar deal with San Erancisco. Chicago andPortland,Ore., are also considering the program. For a $40 annual membership fee, SmartBike users can check out three-speed bicycles for three hours at a time. The program will not provide helmets but does encourage their use. Similar programs have proved successful in Europe. The Ve1ib program in Paris and Bicing in Barcelona, Spain, both started around a year ago and already offer thousands of bicycles. Mr Sebastian, who started trying to bring bike-sharing to Washington even before its success in Paris and Barcelona, said he believed that the program could grow within a year and hoped that it would eventually offer 1 000 bicycles. "But studies showed that many bikes would get stolen in a day, or within a few weeks," said Paul DeMaio, a Washington-area bike-sharing consultant. Improved technology allows programs to better protect bicycles. In Washington, SmartBike users who keep bicycles longer than the three-hour maximum will receive demerits and could eventually lose renting privileges. Bicycles gone for more than 48 hours will be considered lost, with the last user charged a $200 replacement fee. The low cost could be one of the program's major selling points. At GeorgeWashingtonUniversityin Foggy Bottom, one of the program's 10 locations, students were unsure how often they would use SmartBike, but said its price made it worth a try. Options: A the SmartBike company can only make money by renting the bikes B there are many other cities which show great interest in the program C the SmartBike company will be the first one to run bike-renting business D the SmartBike company will have 1 000 bicycles at the renting spots Answer: B there are many other cities which show great interest in the program Question:
