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.
One 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.
Solution is here: How many books are there in the British Library?
Explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Now, solve this: Article: In 1933 an unknown American called Clarence Nash went to see the filmmaker Walt Disney. He had an unusual voice and he wanted to work in Disney's cartoon film for children. When Walt Disney heard Nash's voice, he said "Stop! That's our duck!" The duck was the now-famous Donald Duck, who first appeared in 1934 in the film The Wise Little Hen. Donald lived in an old houseboat and wore his sailor jacket and hat. Later that year he became a star after an eight-minute Mickey Mouse film. The cinema audience liked him because he was lazy and greedy, and because he lost his temper very quickly. And they loved his voice when he became angry with Mickey's eight nephews. Soon Donald was more popular than Mickey Mouse himself, probably because he wasn't a _ like Mickey. In the 1930s, 40s and 50s Donald and his friends Mickey, Goofy and Pluto made hundreds of Disney cartoons. He also made educational films about the place of the USA in the world, and safety in the home. Then in 1966 Donald Duck and his voice disappeared---there were no more new cartoons. Clarence Nash died in February, 1985. But today's children can still see the old cartoons on television and hear that famous voice.
Answer: Pluto
Solution:
Who made Donald Duck film?
