input question: Write a multi-choice question for the following article: Article: Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle. It's the "A-bike", the brainchild of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the world's first pocket calculator. He described his new invention as "the world's smallest, lightest foldable bicycle". "My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used,"said Sinclair. The mini-bike, showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US$300, is built for riders as heavy as 112 kilograms and is height-adjustable . It takes about 20 seconds to fold or unfold. Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters . Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years.???

input question: Write a multi-choice question for the following article: Article: As we know, most of the material things in our daily life have to be bought with money. But money is not all powerful. Money can't buy many things such as time and true love. There are 24 hours in a day. Sometimes when we are very happy, we wish that the period of happiness would last longer. But no matter what we do, or how much money we are willing to pay, we cannot make a day last longer than 24 hours. On the other hand, when we are unhappy, money cannot make the unhappy time pass away more quickly. True love is another thing which money cannot buy. Suppose we have someone who really loves us very much. Once he dies, he can give us no more love. Can our money raise him from death and make him love us as before? Here we can see very clearly that money cannot buy us love. Money can buy us diamond things, beautiful clothes, but never time and love. So money, after all, is not all powerful.???

input question: Write a multi-choice question for the following article: Article: American researchers say drinking tea may help strengthen the body's defense system against infection. Doctors at Brigham and Women's Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That's the letter T, not the drink. Gamma delta T cells are part of the body's defense. First, the researchers mixed some of these cells with antigens found in the amino acid . Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon. In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water. Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon. Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time. Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. "If the findings prove to be true," he says, "then tea drinking might also help protect against bacterial infections." He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body's defenses.???

input question: Write a multi-choice question for the following article: Article: If California were not already so famous for Sillicon Valley and Hollywood, it might be well-known for the groups of water-technology firms in its San Diego County. The reverse-osmosis (RO) spiral module, the technique that supports turning seawater and waste-water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13,000 RO plants in places from the Persian Gulf and Israel to Australia and China. Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south-west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea. The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term "toilet-to-tap" for recycling, even though properly treated waste-water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater. This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module. Lots of people like the idea. Once fully...???
