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 fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
Example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

New input case for you: Article: Everyone would like to be a millionaire, a person with a lot of money, but can you imagine having over $30 million and only being 20 years old? Britney Spears from Kentwood, a small town in Louisiana, is only 20 years old. She is a world famous film star with not only $30 million but also a $2 million house in LA. At her young age, she can look after her family financially all her life. This year is a big year for Britney. She is now on a 31-day tour of the US and every concert is a sell-out. That means she plays in front of a crowd of around 18,000 people every time. It's a tiring schedule but brings her a lot. When touring, she goes to bed around 1 a.m. and then has a lie-in until 1 p.m. the next day. Her philosophy is to take care of the body and relax but always make sure you work hard and have fun. Spears is not pleased with only touring and selling nearly 40 million records so she decided to step into the movie business and try a bit of acting. She made an appearance in "Austin Power 3" this year and she is filming a teenage light play that will come out in March 2003. In this movie, she has a starring role. For Britney, acting is another way to express herself and she is enthusiastic about it all. If her movies are successful, her money in the bank is sure to grow by another few million dollars but she does it for the love, not the money, as she herself tells the reporters.
