input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Hong Kong, a city of seven million--and growing fast. By the year 2050 Hong Kong's population will almost double. Where will these people live? There's only one place to go--up. Fast forward 50 years.This is the tallest man-made structure on the planet. Its name:Millennium Tower. It would stand twice as tall as anything built before. Over 60 thousand people would live or work here. Millennium's designers think it represents the best solution for the coming population explosion. It would cost ten billion dollars and consume more building materials than any single nation could produce. David Nelson, one of Millennium's key designers, said:"It would be a massive project and a world project. But to actually realize it, resources would have to come from all over the globe. The challenge and the motivation for doing it would be to realize one of the world's largest and most complex construction projects." Millennium would be more complex than anything ever built. So its builders won't know for sure the building is safe until it's up, and they can't afford to make an error. Massive earthquakes have brought down entire cities in this part of the world. Can Millennium's designers make it immune to these quakes of the earth? For Millennium, like all the other buildings, safety is just one concern among many. It will need to be a home, one that welcomes people in. Getting people into the building and making sure they have a great experience well be what makes Millennium successful, but how to do it? For the design team, the secret was to bring all the elements of city life within. Cafes and restaurants, theatres and stores would provide entertainment. Health clubs, even schools and medical clinics would also serve the towers' residents. Millennium's designers have proven something. Things that seem impossible today, might just become reality tomorrow. The engineering problems have, for the most part, already been solved. Our achievements are limited only by our imaginations.

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The Couch Surfing network is an online community stretching across the globe with over one and a half million members. The basic concept is to provide a platform for travelers to contact people who are willing to put them up free of charge. Travelers connect with potential hosts online and, if they like each other, exchange details to make farther arrangements. Basil is one traveler from Switzerland who is currently couch surfing with a Chinese host in Beijing. "I thought staying in hostel is nice but you mostly meet foreigners and speak English. If you use Couch Surfing you have chance to meet people living here and really get a chance to know the life of the place you visit. " Basil was speaking during a regular meeting of Beijing network of Couch Surfing with a membership of almost 2,000. Although some people may have concerns about meeting complete strangers and giving them full access to your house, Beijing group member Fred Sharp from California says that the Couch Surfing community is one that generally attracts trustworthy people. "I have never had a problem with guests. I'd say that this Couch Surfing community worldwide is a fairly trustworthy community like I say, always be cautious, make sure that you read everyone's profile that you're considering hosting, and if it doesn't feel right just say' no', it's OK. " Originally launched in the US as a non-profit organization in 2004, Couch Surfing is growing fast across the world. China is no exception with around 30,000 members and hundreds more signing up each week. One of them is Beijing resident Hai Yan who joined in November 2009. She says the first time she hosted a guest was a very positive experience. "My first guest was from Italy. He was very kind and helpful. He bought me a present from Italy, a handbag. It's a famous brand!" As the organization grows from strength to strength, hotel owners across the world will be watching very closely and possibly thinking twice about raising their prices too high. Options: A Couch Surfing has a long history B Hai Yan is satisfied with her host C Couch Surfing is getting popular in China D Basil works at the Beijing Network Answer: C Couch Surfing is getting popular in China Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Mona Lisa, the mysterious woman in Leonardo da Vinci's 16th century masterpiece, had just given birth to her second son when she sat for the painting, a French art expert said on Tuesday. The discovery was made by a team of Canadian scientists who used special infrared and three-dimensional technology to study the paint layers on the work, which now sits in the Louvre museum in Paris. Bruno Mottin of the French Museums' Center for Research and Restoration said that on very close examination of the painting it became clear that the Mona Lisa's dress was covered in a thin transparent gauze veil. "This type of gauze dress was typical of the kind worn in early 16th century Italy by women who were pregnant or who had just given birth. This is something that had never been seen up to now because the painting was always judged to be dark and difficult to examine," he told a news conference. "We can now say that this painting by Leonardo da Vinci was painted in memory of the birth of the second son of Mona Lisa, which helps us to date it more precisely to around 1503."The young woman with the ambiguous half smile has been identified as Lisa Gherardini, wife of Florentine merchant Francesco de Giocondo. She had five children. "People always wrote that Mona Lisa had allowed her hair to hang freely over her shoulders. This greatly surprised historians because letting your hair hang freely during the Renaissance was typical of young girls and women of poor virtue ," he said. The team had hoped to discover more details about Leonardo's painting techniques, which the artist used to create a hazy effect. But scientist John Taylor said the team had been disappointed by the lack of brush stroke detail on the painting.

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients' life.Called the Biologic-HT System, the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body. The heated blood causes the patient's body temperature to rise above 42 degrees Celsius. In people with AIDS, that increase in temperature kills some heat-sensitive HIV, the virus, most doctors say, causes AIDS. Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects. The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn't kill all traces of the virus. However, it kills enough virus particles to give a patient's immune system a reprieve in its deadly duel with HIV. Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning. So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections--disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV. Options: A disappointing B incomplete C successful D surprising Answer: C successful Question:???

The result of the experiment seems to be _ .
