When Jon and Sandy go to the store or to their daughters' soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world's most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline.

This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. "The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment," scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use.

Write a multi-choice question for the following article, with the given choices and answer: Article: WUHAN - A 72-year-old woman, Wang Yulan, has started legal procedures against Carrefour after she was falsely accused of stealing in the supermarket. Wang's lawyer Wen Jun said they filed a lawsuit at the Donghu district court, making two demands. First, Wang wants Carrefour to make a public apology and the apology letter should be put up in the Carrefour store or in the media. "We also demand 50,000 yuan in compensation for my wife's psychological injuries," Wang's husband, Yan Fucun, said, "We don't mean to _ money from Carrefour, but asked for it as a recognition of respect. Besides the money spent on lawsuit costs, I will donate the rest to charity." Wang earlier said she went to the store's Guanggu branch to buy cereal. She picked up 20 packs of a particular brand and was given another four as gifts by a saleswoman. However, when she arrived at the checkout, the cashier insisted Wang pay for all 24 packs, which led to an argument. The saleswoman later denied she said the extra packs were free. A store supervisor led Wang to an office, accused her of theft and had her sign a form and pose for photos. Wang and her husband returned to the store the next day with the local media to demand an explanation. Carrefour China then apologized for the incident on its Sina micro blog, saying the managers and staff members involved have visited Wang's home and apologized. The company also sent three apology letters to Wang in the following three days. Eric Legros, president of Carrefour China, said,"We made a mistake and we apologized four times. Four times, you know. And Carrefour will not do anything more about it." Wen Jun said the supermarket's management came with risks. For instance, Wen said the company would offer employees money if they caught a thief in the store. "I hope this case will be a warning for the staff who want to get money by such an immoral method," Wen said.

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: At the age of sixteen,I joined a volunteer group with my dad. I went on my first volunteer project in West Virginia. On the night we arrived, we discovered that "our family" was living in a trailer that was in poor condition. A crew had been working on it for two weeks,but every time they finished one problem,another surfaced(, ). We decided the only reasonable solution was to build a new house--something unusual but necessary under these circumstances. The family was overjoyed with their new house that was twenty by thirty feet with three bedrooms,a bath and a kitchen. On Tuesday of that week, while we were eating lunch together,I asked the family's three boys,Josh,Eric and Ryan,"What do you want for your new room?"Expecting toys and other gadgets that children usually ask for, we were astonished when Josh responded,"I just want a bed." The boys had never slept in a bed! They were accustomed to plastic mats. That night we had a meeting and decided that beds would be the perfect gift. On Thursday night, a few adults in our group drove to the nearest city and bought beds and new bedding. When we saw the delivery truck coming,we told the family about the surprise. We could hardly control ourselves. It was like watching excited children on Christmas morning. That afternoon, as we fitted the frames of the beds together, Eric ran into the house to watch us. Too dirty to enter his room,he observed with wideeyed enthusiasm from the doorway. As my father slipped a pillowcase onto one of the pillows,Eric asked,"What is that?" "A pillow," he replied. "What do you do with it?" Eric continued to ask. "When you go to sleep,you put your head on it," I answered softly. Tears came to my eyes as my father handed Eric the pillow. "Oh...that's soft," he said,hugging it tightly. Now,when my sister or I start to ask for something that seems urgent,my dad gently asks, "Doyouhaveapillow?" We know exactly what he means. Options: A what they want to get may be unnecessary B they should not waste money on small things C they should do more volunteer work for the poor D what he will buy is not what they want but a pillow Answer: A what they want to get may be unnecessary Question:
