[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Compared to high heels , they don't look dangerous, but flip-flop wearers should think twice before slipping on a pair. The National Health Service spends PS40 million a year treating injuries caused by wearing the casual footwear. More than 200,000 people end up in hospital every year after suffering falls or developing long-term problems. Once worn only at the beach, flip-flops have become the regular summer footwear of choice for women, with two in five women owning at least one pair. But experts are warning the public of the dangers of wearing flip-flops, such as the risk of joint pains. They say flip-flops force people to change the way they walk so that when taking a walk with long steps they put pressure on the outside of their foot, rather than their heel, causing long-term damage. And there is also the risk of serious injury. Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground. Many also suffer aching toes as they constantly wear them. Mike, a spokesman, warned wearers of the damage done by flip-flops. He said, "They land on the outside and then roll the foot inwards putting all the pressure on the big toe." This constant rolling puts pressure on the ankle joint, causing it to weaken. The lack of support of the flip-flop also causes pain on the inside of the foot and lower leg. And if you're not used to wearing them, they can cause blisters , he added. Doctors say flip-flops cause far more damage as they are worn for longer periods of time. Emma Supple, consultant podiatrist , said, "Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that wearing on hard flat surfaces can cause considerable foot and leg problems." She encouraged women to wear suitable shoes to help recover from summertime injuries. Options: A The benefits of wearing high heels. B The dangers caused by wearing flip-flops. C The advantages and disadvantages of wearing flip-flops. D Some advice on how to avoid injuries caused by wearing high heels. Answer: B The dangers caused by wearing flip-flops. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don't be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows. Approximately the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone." More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported _ a phone call. That's not all, however. What goes on behind the walls of the stalls is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom -- 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues. As expected, Gen Y respondents are the pacesetters in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers and 47 percent of the Silent Generation. While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom - 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall. "The writing is on the stall," said 11mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private." In the process, high-tech hygiene is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent...

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: You may have heard the term "the American Dream". In 1848, James W. Marshall found gold in California and people began having golden dreams. That 19th century "American Dream" motivated the Gold Rush and gave California its nickname of the "Golden State". The American Dream drove not only 1800s gold-rush prospectors but also waves of immigrants throughout that century and the next. People from Europe, and a large number of Chinese, arrived in the US in the 19th century hoping that in America they would find gold in the streets. But most, instead, worked as railroad labourers. They created the oldest Chinatown, in San Francisco, and gave the city a Chinese name "the old gold hill". In the 20th century, some critics said that it was no longer possible to become prosperous through determination and hard work. Unfair education for students from poor families and racial discrimination almost made the American Dream a nightmare. Then, in the 1990s, California saw a new wave of dreamers in Silicon Valley. People poured their energy into the Internet. This new chapter of the American Dream attracted many business people and young talents from China and India to form start-ups and seek fortunes in America. Better pay, a nice house, and a rising standard of living will always be attractive. However, the new American Dream is no longer just about money. It encourages Americans to consume wisely to protect the environment, improve the quality of life, and promote social justice. The Governor of California, Arnold Schwarzenegger, has become the model of the new American Dream. After years of hard work, he grew from a poor young man from Austria into a movie superstar and then governor. Many people hope his story can save the American Dream and give California a brighter future. Options: A Because they could earn more money as railroad laborers.

Answer: B Because they had to make a living by working as railroad laborers. Question:
