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. 
 Answer: whether mood affects their learning ability
Example solution: Researchers did experiments on kids in order to find out _ .
Example explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

Problem: Article: Part of the magic in movies is the costumes. They can transform a normal-looking actor into a cowboy, a space alien or even a superhero. Costumes for movies are designed and created by a whole team of people, according to Courtney Daniel, a Toronto-based costume designer who worked on the recent movie Night At The Museum. As a designer, she does research to find out what details are needed to make a costume work, and what makes sense for a specific movie. In Night At The Museum, she and a few other designers spent time at libraries and museums studying everything from what cowboys should wear, to what ancient Egyptians and Huns would have put on. Once they got the information they needed, they figured out what fabrics   to use and how to put them together. The designers even changed a few details to make the costumes more "movie friendly". For example, more colour and extra touches  helped historical costumes to be alive for kids. One example of this is the costume for the role in the movie Night At The Museum, an Indian woman Sacagawea, which has a shorter skirt and fits more closely than the clothes the real Sacagawea would have worn. Daniel has also worked on costumes for other big-name movies, such as the second and third X-Men movies, and Catwoman. If you are. interested in being a costume designer, it helps to have an interest in sewing. She said,"Learning how to sew, and how different fabrics and materials work is important."So is knowing how to carry out research, Daniel's degree in art history helped in this area.
