[Q]: Write a multi-choice question for the following article: Article: International experts meeting in Australia say global carbon emissions can be reduced by more than 50 percent through simple energy saving measures. People at a conference in Australia, which increasingly relies on coal for power, say that reducing power consumption is an affordable way to both cut energy costs and reduce pollution. While many nations turn to cheap and dirty energy sources, such as coal, to meet their increasing energy needs, analysts in Australia say the best way to meet those needs is to improve energy efficiency. A range of simple solutions include using energy-efficient homes, household appliances and lighting, and driving electric cars. Encouraging homeowners and office workers to switch off their televisions and computers at the end of the day is also seen as an effective way to save electricity. Grayson Heffner, from the Paris-based International Energy Agency, says reducing consumption could greatly cut global carbon emissions. He calls efficiency strategies the "soft giant" of clean energy. "We forecast that energy efficiency will deliver something like three-quarters of the greenhouse gas emissions reductions over the next 20 years. So in the short term energy efficiency is the main way that we reduce greenhouse gas emissions but oftentimes it is not so importantly stressed in the discussions," said Heffner. Energy experts working in China say the government is making significant cuts in power usage. Wan Xingwang, a Beijing-based representative of the Energy Foundation, a U.S. non-government organization, says the results have been impressive. "In the past five years China achieved about 19.1 percent of energy reduction of its GDP. That translates to something like more than 600 million tons of coal savings," said Wan Xingwang. While most nations have some sort of government-sponsored energy efficiency programs, energy analysts say initiatives by individuals and companies can also help cut demand. Steven Nadel, executive director of the American Council for an Energy Efficient...

input: Please answer the following: Write a multi-choice question for the following article: Article: Liu Xiang Will Resume Training prefix = st1 /Athens Olympic 110m hurdle champion Liu Xiang felt so _ to return to racetrack after getting out of the great number of social activities. Liu arrived in hometown ShanghaiWednesday night and was about toresumetraining shortly after. "I am so exhausted from so many social activities, which made me even more tired than training," said the 21-year-old Liu, who wrote a new chapter in China's Olympic history by winning the country's first ever athletics short-distance running title in the men's 110m hurdles in Athens in August. "I am happy that I will resume my training soon back in Shanghai," said the Shanghainative. He turned into an instant national hero with the Olympicglory(,)and one of the most popular Olympic gold medalists, taking part in scores of celebration activities since he returned to China early September. "My regular training has been interrupted for such a long time that I think I can only run at about 13.5 seconds now," said Liu, who clocked a world record-tying time of 12.91 to clinch the title. "I would rather forget what I have achieved in the past and try my best to realize a higher goal," he said. Liu already missed the Berlin Golden League Series on Sunday and won't be able to catch the IAAF Grand Prix final slated for September 18-19 in Monaco. He plans on attending an IAAF all-star tournament in Japanat the end of this month.

Please answer this: Write a multi-choice question for the following article: Article: Is been a dream for 30 years but now the world's first flying car is set to hit the roads this year. Ever since the"Back to the Future"movies lit up our screens in the 1980s,designers have dreamt of cars that could take to the sky at the push of a button. And now pilots can order their own "roadable"plane for just PS 127,000. The plane,which has fold-out wings that span 17. 5 ft,has a range of flying distance of 460 miles and can be up to 115 mph. Back on the land,it can also travel at"highway speeds" in car mode . Fuelling the 19 ft long plane couldn't be simpler--you just drive it into a petrol station and fill it up. A spokeswoman said,"You can keep you 'light-sport airplane'in your garage. But because _ needs a short runway to take to the air,you will have to drive to your local airport,fly up to 460 miles,land,and drive directly to your destination. You will always be ready to drive or fly. " The spokeswoman added,"Never let bad weather change your trip. You call simply divert and continue on the ground until the weather clears. " There's no risk to you--This is only the chance for you to be the first at your home field to unfold your wings and fly into the future.

Problem: Write a multi-choice question for the following article: Article: A patient on the brink of death has received the world's first self--contained artificial heart--a battery--powered device about the size of a softball that runs without the need for wires,tubes sticking out of the chest.It is powered by a small battery pack worn outside the body that transmits current through the skin. Two surgeons from the University of Louisville implanted the titanium and plastic pump during a seven-hour operation at Jewish Hospital Monday.The hospital said the patient was''awake and responsive''Tuesday and resting comibrtably.It refused to eve personal details. The patient had been expected to die within a month without the operation, and doctors said they expected the artificial heart to extend the person's life by only a month.But the device is considered a major step toward inlproving the patient's quality of life. The new pump,called AbioCor,is also a technological leap from the mechanical hearts used in the l980s, which were attached by wires and tubes to large machinery outside the body.The most famous of those, the Jarvic-7,used air as a pumping device and was attached to an apparatus about the size of a washing machine. ''I think it's potentially a major step forward in the artificial heart development,''said Dr.David Faxon,president of the American heart Association.However,he said the dream of an implantable,permanent artificial heart is not yet a reality:''This is obviously an experimental device whose long--term success has to be demonstrated."Only about half of the 4,200 Americans on a waiting list for donor hearts received them last year,and most of the rest died. Some doctors,including Robert Higgins,chairman of cardiology at the Medical College of Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts."A donor heart in a good transplant can last l5 to 30 years.''he said.''It's going be hard replace that with a machine.''

A:
Question: What can we learn about the Jarvic-7?Options:A It is a technological leap today.B It could be used most widely in the l 980s.C It is as advanced as AbioCor.D It must be attached to a washing machine.Answer:B
