In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally. Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light. The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used. Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed. Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen "fuel cells" for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars. The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth's population that has no electricity. And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night. Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by _ . With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the "world-wide hydrogen web," which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source. Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
Answer: It has to be separated from other materials.
Example Output: What is the problem with using hydrogen as energy?

Example Input: Article: When a dog bites a man, it usually doesn't make news. However, this saying change when Beijing and several other Chinese cities announced the "Civilized Dog Raising" campaign in November. The government will require Beijingers to get licenses for their dogs, and will enforce the one-dog, one-family policy. Police say the "one-dog policy" is aimed at reducing the number of dog bites and lowering the risk of rabies. According to the Ministry of Health, rabies has become the top infectious disease in China. Dangerous dogs and dogs taller than 35 centimeters, such as Great Danes, have been banned from urban areas. Pet owners are also required to clean up their dog's droppings and make sure dogs are leashed , especially in public areas. Some public areas, such as banks, are closed to dogs entirely. Dogs are regarded as man's best friend and the history of raising dogs can be traced back to the stone age. It therefore seems sad that dogs are unwelcome in Beijing. But it is not the case that Beijingers dislike dogs. Actually, there are many dog lovers in Beijing. The city now has more than 550,000 registered dogs, up 20 percent from the previous year. The problem is, actually, about living space. Different from many Westerners, most Beijingers live in urban apartment buildings, not houses in the suburbs. There is very limited open space for walking dogs. The barking, the waste, and unleashed dogs in buildings, elevators and places people gather can cause fear, fights and frustration. Beijing is not the only city to have a dog problem. Paris, London, New York and Vienna all face similar challenges and have common rules for dogs and their owners.
Answer: Civilized Dog Raising
Example Output: Which of the following may be a suitable title for the story?

Example Input: Article: In Asia,there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them.Although all kites have a similar structure ,they are widely different in size and shape.Kitefighting competitions are also held,in which competitors use their kites to attack and bring down their opponents' kites or cut their strings . For more than 15 years,the Big Wind Kite Factory has been giving kitemaking and kiteflying classes for the children on an island in Hawaii.In its kitemaking lessons,students can make kites in as little as 20 minutes!Children as young as four years old can learn how to fly a kite.Jonathan Socher and his wife Daphne started the kite factory in 1980.Their kites are made of nylon .Their designs are Hawaiian themes created by Daphne.The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite. The kite that is used to give lessons is a regular diamond kite with a rainbow pattern.The difference between this kite and the ones they make during the lessons is that it is a twostring controllable kite.Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in.Then the controls are given to the students. Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites.Even the simplest structure can work,and can give hours of fun.Go on,give it a try!

Answer: Daphne designs kites for the Big Wind Kite Factory.
