Given the task definition, example input & output, solve the new input case.
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: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Output: How many books are there in the British Library?
In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

New input case for you: Article: With eight bloodshot eyes fixed on a flying object, the pains of a two-year project were about to bear fruit. It was Wang Hongyi's first test flight of an unmanned aerial vehicle (UAV) designed and assembled with his teammates from the Aero-Sport Club at Shanghai Jiaotong University. Wang is a senior mechanical engineering and automation major. He has been a plane model fan since childhood. As a freshman, he spent two nights building a model aircraft and took it to the sports field just for fun. Wu Junqi, the coach of Shanghai Jiaotong University's Aero-Sport Club, spotted Wang and told him his model was outdated. "I was a little angry, so he took me to the lab," says Wang. He was immediately drawn to the modern equipment and decided to join the club. As a technology fan, Wang spends most of his spare time in the lab. "He loves what he's doing, so he can stand the loneliness of doing research that others seldom have the persistence to carry out." says coach Wu. When Wang and his teammates were building UAV, they lived together in the lab. "We tried to spend as much time together as possible because there were thousands of problems that needed to be solved." Wang says. They didn't even have time to celebrate when the first test flight of the UAV went well. "We needed to list the problems that occurred during the flight and analyze them to find solutions." he says. "Our UAV isn't finished yet, but there are many design projects and people with similar interests waiting for me." Wang says. "The UAV is just the beginning, not the end of my aircraft journey."
Answer: He was highly thought of by Wu Junqi.
Output:
Why did Wang succeed in doing the research?
