Write a multi-choice question for the following article, with the given choices and answer: Article: The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis. Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles--nearly the size of Mongolia--to meet the needs of 1.47 billion more people living in urban areas. "It is likely that these cities are going to be developed in places that are the most biologically diverse," said Karen Seto, a famous scientist at Yale University. "They are going to be growing and expanding into forests, biological hotspots, savannas , coastlines--sensitive and _ places." Urban areas, they found, have been expanding more rapidly along coasts. "Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters," said Seto. The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. "We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing," she said. "Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion to changes in local and regional climate." The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world's urban footprint had grown by at least 22,400 square miles--half the size of Ohio. "This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data," said Seto. "We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we're not tracking the physical expansion of more than half of the world's largest cities." Half of urban land expansion in China is driven by a rising...

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Matt and his wife lived in the country. Matt was very mean and hated spending money. One day a fair came to the nearby town. They went to the fair and looked at all the things to buy. Matt's wife wanted to buy a hat only costing $28, but was refused. Later on, a comb of $5 attracted her attention, but he would not let her spend any money. Then, in a nearby field, they saw a small airplane. "Fun flight!" the notice said, "$10 for 10 minutes." Matt had never been in an airplane and he wanted to go on a fun flight. However, he didn't want to pay for his wife either. "I've only got $10," he told the pilot. "Can my wife come with me for free?" The pilot wasn't selling many tickets, so he said, "I'll make a bargain with you. If your wife doesn't scream, she can have a free flight." Matt agreed, and got into the small airplane with his wife. The pilot took off and made his airplane do all kinds of things. At one moment it was flying upside down. When the plane landed, the pilot said, "OK, your wife didn't make a sound. She can have her ride free." "Thank you," Matt said, "it wasn't easy for her, you know, especially when she fell out." Options: A throw the wife out of the plane B get another $10 by making the wife shout C show off his perfect flying skills D provide the couple with pleasure of excitement Answer: B get another $10 by making the wife shout Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Superstorm Sandy's march of destruction claimed at least 43 lives and left more than eight million people without electricity by late Tuesday, in one of the largest storms ever to strike the East Coast. Less violent but still dangerous, the storm swept across Pennsylvania on Tuesday and the northeastern US began its slow process of recovery. As dawn broke Tuesday on the storm's trail of destruction, it began exposing stories of heroism and tragedy, bad decisions and lucky breaks. In Broad Channel in New York City, a 29-year-old mother was forced to dive and swim out of her house's front window with her 8-year-old daughter. And in Freeport, N.Y., Nicole Smith returned home --- to find a boat on her lawn. She asked passers-by for $5 to take a snapshot. A 13-year-old girl was found dead, in her pajamas, a block from her washed-out Staten Island home. On Monday night, Sandy's waves ripped out the entire deck of Jeffrey Ratner's home, along with the back wall. Still, Mr. Ratner said, he remains optimistic about the future. "We are going to rebuild it," he said. The official warnings to evacuate were clear, a couple said. But staying home just seemed easier. "It's not their fault; it's ours," said Mary Norton, 88, head in her hands. "We did not leave." New York's extensive transit system, a lifeline for millions of commuters , suffered the greatest damage as floodwaters drowned all seven subway tunnels connecting Manhattan and Brooklyn. Jseph Lhota, Chairman of the Metropolitan Transportation Authority, described it as the most destroying in the 108-year history of the New York subway. Forecaster said Sandy, which had maximum continuing winds of 45 miles an hour Tuesday afternoon, would cross western Pennsylvania on Tuesday night before moving into Canada on Wednesday as it meets cold air fronts. Another inch of rain was expected from the eastern Great Lakes across the mid-Atlantic and into southern New England. Options: A It had killed at least 43 lives when the news was released.
