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: Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice-skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time. Stand Straight The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all. Confidence is What You Need The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slope every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor your skates. Keep practicing this till you are confident about it. Maintain Speed Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling , that is, keep pushing yourself backwards with an outwards stroke . Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough. Increase Your Speed Now Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time. Scull and Be Aware While you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.
