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.

Let me give you an 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.

Article: You're jogging at a steady pace, enjoying your favorite music through your headphones. Your breath is short and your heart is pumping. Your legs feel like they couldn't carry you any faster. And then you hear the groan of a zombie over your right shoulder. You must run or be eaten. The zombie apocalypse isn't upon you. You're just taking part in the latest fitness craze--Smartphone apps that make a fun and interactive game out of your daily workout. Software developers are taking advantage of Smartphone's advanced technology--GPS, accelerometers , MP3 players--to create "immersive" fitness games that appeal to both desperate and reluctant exercises. It's part of an overall trend in the fitness industry toward making your daily workout "a fun experience rather than something you have to do," said Jessica Matthews, an exercise physiologist for the American Council on Exercise. "We are attempting more "play" opportunities as opposed to working out, basically getting people to move and having fun while they are doing it," Matthews said. One popular fitness game app, Zombies, Run!, places you in the role of a supplies runner for a walled community trying to survive against the walking dead. During your run, the game's surprising complex story unfolds through your headphones. You "pick up" supplies for the community as you jog along. At certain intervals, you're warned that zombies are nearby, and if you don't pick up the pace, you'll have to pitch some supplies to keep from being caught. The game doesn't end once your jog is over. After your workout, you can use the supplies you picked up during your running to fortify your community. The GPS statistics from your run are uploaded automatically to the game's website, so you can review your average speed and the estimated calories you burned. Teemo, Nexercise and Fitocracy all allow you to post your latest workout to share with friends. Some games have you work with friends to reach a common goal--completing a relay race, for example--while others encourage competition. "That's another big area, having that social component," Matthews said, "Having social support of some kind is a critical factor in adhering to an exercise program. For some people, having that friendly competition or the feeling of being on a team can help them stay motivated."
