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.

Problem: Article: As Paige watched the other kids playing football in her local park she longed to join in. But at nearly nine stone (1stone equals 6.35 kilograms), the 11-year-old was too big to enjoy her favorite sport, she was well on her way to being another overweight member of her family. Mandy, her mum was 17th 10 lb and Anne, her grandma 15th 10 lb.   Mandy, 39, and Anne, 67, both have a sweet tooth and share a love of all things stodgy. Recent figures show that two-thirds of kids will be dangerously fat by 2050, and overweight kids often become obese adults and live shorter lives as they are at higher risk of everything from heart disease to cancer and type-2 diabetes. Mandy says she knew things had to change for her and her family. Mandy's mum Anne had an even greater motivation for wanting to slim down. Last autumn Paige went along to the Slimming World to keep her mum and grand ma company. In the first week on the Slimming World eating plan, Mandy lost a whopping 9.5lb. Mandy asked Paige to join in. They believed the Free2Go plan is balanced and nutritious and doesn't deprive Paige of anything.   Supporting and encouraging each other the whole time, Anne, Mandy and Paige all whittled away their waistlines. Mandy says: "My back problems have cleared up." Anne has also noticed a real difference in her health. She says: "I feel like I've got my old energy back." Paige is almost as delighted with her new wardrobe as she is about her foot balling skills. Mandy adds: "I'm just so proud of Paige. I felt awful because I knew her weight problems were a result of my bad eating habits. But when I see her now it's like she's a different person."
