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: A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants. Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules  .It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles. The team calculates the Car-puccino will do three miles per kilo of ground coffee   -- about 56 cups of espressos   per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours. Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much. Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn't matter." He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste. 
 Answer: It should be very dry.
Example Output: Which is the right way to choose the coffee used as fuels to run the Car-puccino?

Example Input: Article: Columbus made four voyages to the west between 1492 and 1504 in his vain search for a sea route to Asia. The mystery of why he failed to find it haunted  him and filled him with sadness. Wherever he went to Cuba, Puerto Rico, Jamaica, South America, Panama, down the coast of Central America--it was always the same story. Instead of golden palaces, there were grass huts and palm-leaf tents. Instead of silk-robed merchant princes, he found "Indians" who did not have so much as a shirt on their backs. When Columbus explored the West Indies in 1493,he heard tales of a fierce Indian tribe who literally devoured its defeated enemies after a battle. These people were called by many names in the area, including Calina, Canima, Carib, and Caniba. Columbus recorded the name of the American natives as Canibales in Spanish, a word which came to refer, within a few years, to any eater of human flesh. In the similar fashion, the word Caribbean, a title for the sea as well as for the region, came into English. At times Columbus knew that this new land was not China, not Japan, not the Spice Islands. He seemed to accept it as a part of the earth that the geographers of Europe had never heard of before. It was another world--and he called it exactly that--but Columbus also insisted until he died that land he had reached was an unknown part of Asia. 
 Answer: Columbus' voyages
Example Output: What is the best title for this text?

Example Input: Article: For years I fought with the bird's nest that sat on top of my head-my Medusa  hair.No matter what I did and how hard I tried, in no way could I make my unruly  hair to my satisfaction. Growing up in a Russian-Jewish home with parents who thought North American styling products were something illegal such as drugs, I was never allowed to put them in my hair. "Why buy hair gel? Your hair is so beautiful naturally." my mother would say.The teens at school did not agree.From boys' not wanting to kiss me when we played spin the bottle in Grade 7 to being called the mop, I suffered from my hair. When I got to university, I believed my hair was a wall that stood between me and everything---finding a part-time job, getting a boyfriend, etc. If only I could find a way to manage the curls and put it behind bars, I told myself, I would feel secure and sexy.I tried everything: rollers, hairspray, gels and, at one point, an iron.Then, in my second year, a miracle happened.I was asked to be a hair model for Japanese hair straightening, a process by which the molecules of my curls would be broken and reset in a bone-straight position.I was the perfect candidate, the hairdresser told me.Although they said how hair relaxing could damage the scalp  , for the next five years I didn't find them to be true. All of the hairdresser's promises were fulfilled: With my hair straight and smooth, I was no longer the " mop". However, there was extreme damage done to my wallet. To keep up the straightening cost $ 700 every six months, and that was considered cheap. While some people thought I was crazy, I was willing to do anything to never again feel like that anxious, curly-headed girl in Grade 7.But when I moved out of my parents' house at age 26 and rented an apartment, the upkeep of my new image became too costly. I couldn't hide from my inner Medusa any longer.It was time to hug her and let her fly.Seeking a choice, I turned to the Internet, Google.After hours of searching, I hit upon a "curly haired" salon, a place designed for girls like me. I doubted these so-called "Curl Ambassadors" could do anything without using machine of some sort, and though I bought the service called the "Curly-Doo", I suspected I'd have the same unruly mop at the end of the appointment. I dragged my feet so hard getting there that I arrived 45 minutes late.I secretly hoped they would turn me away.Instead, my stylist simply said: "You are very late.Let me see your hair". At that moment, my world and beliefs about myself were turned upside down along with my hair. As my head was in a basin full of freezing-cold water, then covered with a jelly-like jam, I wondered what I had got myself into. "Do you really think this will work?" I asked the stylist, Jones." My curls are a disaster." "No curly hair is hopeless," she replied."They just haven't found a way to work with it, that's all." After the hour was over, Jones had completed her work.She had styled my hair using only her hands, water and a mixture of organic jam.I couldn't believe what I was seeing in the mirror: a naturally curly, Medusa-free me.You could argue that hair is just hair. Yet, it is just such physical features that have such a large influence on how we view ourselves. According to Jones,75 percent of the population have a wave or curl in their hair and don't know what to do with it.Men cut theirs short.Women flat-iron theirs to death.When I read through a beauty magazine or take the subway to work, it makes me sad to see so many people repressing their natural beauty. Since then, my world has changed.I have always been outgoing, but these days I seem to be more outspoken and confident than ever.On top of that, friends and co-workers tell me I am looking better than ever, but they don't know the source of the change. I don't need to tell them. My Medusa hair speaks for herself. 
 Answer: North American styling products harmed her hair.
