Write a multi-choice question for the following article, with the given choices and answer: Article: London used to be "foggy" for the same reason that cities like Beijing or Chongqing are "foggy" today. The "fog" was in fact smog, a mixture of smoke and fog. In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal that people burnt in their houses to keep warm during the winter. By the 1950s, London's smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more " _ ". Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people's houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel , like gas, is quite expensive. However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer "pea-soupers" in Beijing than there used to be. Options: A There was not so much fog in the winter later. B A law was made to keep people from burning coal in their houses. C Many factories in the city were closed. D People paid more attention to cleaning their city. Answer: B A law was made to keep people from burning coal in their houses. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: London, May 5, 2003 Emma Richards of Britain has become the first woman and the youngest person to finish the Around Alone, which is a round-the-world sailing race. The journey started in New York last September and went east around South Africa to New Zealand. It crossed the Pacific Ocean and went around South America, ending up yesterday in Rhode Island, the smallest state in America. In the end, the trip covered over 46,000 kilometres. The same sea route was taken in the past by many famous travelers who wanted to learn about the world. Emma, a 1996 graduate of the University of Glasgow, finished the race at the age of twenty-eight. The race requires competitors to sail alone. Emma said that actually it was very difficult to be all by herself for such a long time even though she's really into sailing. Her worst moment was when she had to climb the high mast in a bad storm to fix some broken parts. She sailed hundreds of kilometres away from land and the wind was blowing very hard. Only her strong willpower kept her going to make it all the way. These days, Emma is happy to be home with her parents and sleep in a bed that stays still. Options: A About four months.

Write a multi-choice question for the following article, with the given choices and answer: Article: Answers to life can be found in everyday events. Watching nature, watching people and watching animals communicate with each other provide some of the simplest ways to life's biggest problems. This became clearer to me yesterday. It caused me to ask myself, "How do I respond to the storms in life?" People usually run when it starts to rain. I love to walk in it, stand on my front door and feel it. I grew up doing it and have never really felt the fear many people do. The animal world senses changes in the weather far earlier than humans. My dog, Ricky, begins to shake long before the storm is close enough to be noticed. I was about to feed my three dogs yesterday and as usual, I let them out in the yard first. They didn't move when thunder came across the skies. So I placed their food in their bowls and called Ricky into the kitchen. Ricky was just standing there in place next to his bowl. The thunder became louder, which forced him to stop eating his meal. Then I watched Phil. He made his way across the kitchen floor and stood over Ricky's bowl. He ate all the remaining food. Generally, if Ricky was standing there, he wouldn't dare come close. But today, he took advantage of the storm and got what he wanted. His hope for the prize outweighed his fear of the storm. That's when it hit me. As men, we face all kinds of storms. They come in unannounced. Sometimes we stay in a corner or under the blankets, hoping it will all pass. However, if you dare put your head out, you'll discover there're people doing what they must to get what they must have out of life. Isn't it time you decided to take advantage of the storm? Options: A are difficult to find B lie around us C are simple to understand D make people become fearless Answer: B lie around us Question:
