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.

Input: Consider Input: Article: New York Hall of Science (NYHS) Founded in 1964, it is New York City's only hands-on science and technology center. Being an interactive science museum, it has the largest collection of hands-on science exhibits in New York City, exploring biology, chemistry and physics. The museum focuses on education for children aged 5 and up, with the aim of conveying the excitement and understanding of science and technology to children. Queens County Farm Museum (QCFM) The museum, dating back to 1697, is the only working historical farm in New York City. It is an actual farm and you can wander around the farm to see the fields and animals. It's a good chance for your kids to meet sheep, goats, pigs, chickens and cows! The museum sells feed for young hands who are willing to get licked by sheep and goats. The animals are friendly to visitors. The museum also offers many exciting hands-on programs, such as Apple Pressing Workshop, Honey Bee Alive and a lot more. American Museum of Natural History (AMNH) It is one of the largest and most famous museums in the world. With a history of 143 years, the museum is well-known for its collections and exhibitions representing people and animals throughout the ages. One of the museum's great attractions is a series of fossil halls that include the must-see dinosaur wing. It also provides hands-on events for school groups of all ages on a variety of topics. Museum of the Moving Image (MMI) The museum originally opened in 1988 and reopened in January 2011 after a $ 67 million expansion. As the best media museum in New York City, it promotes public understanding and appreciation of the art, history, technique and technology of film, television and digital media. With a balance of hands-on activities and information, it can entertain and educate people of different ages.
Answer: It is an open-air museum.

Output: What can we learn about Queens County Farm Museum?

Input: Consider 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.

Output: What is the problem with using hydrogen as energy?

Input: Consider Input: Article: A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy and speed,The Telegraphreported. Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side. The company gave 26 participants a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all. The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, toldThe Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... _ are going to become more positive about the work." However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.
Answer: Music helps us to learn
