Problem: 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: The Smurfs --cute little blue cartoon dwarfs inspired by Nordic fairy tales made their first TV appearance in the US in 1981 and ever since have been childhood friends to many people across. The storyline is quite simple. The Smurfs are living happily in their mushroom houses in the middle of a forest.Then one day the evil wizard Gargamel discovers their village and sends them by magic to present-day New York City. The Smurfs have to find their way home and conquer Gargamel along the way. So, just why, more than half a century later, is the simple story still so beloved by young and old? Mario Cacciolotto, a BBC reporter, believes it is due to the fact that the Smurfs' lives do not have any particular cultural implication and argues that they could offer a model for society. Veronique Culliford, daughter of the Smurfs' creator Pierre Culliford, agrees."They are unique creations," she says, "They do not do politics or religion.They are multi-cultural and everybody around the world can recognize themselves in the Smurfs.Everyone can apply their very nice values of friendship, kindness and helping others to their own lives, regardless of where they come from". In the Smurf world , everyone has their own skill and is willing to use it for the benefit of others without expecting any reward.Their village is run as a collective and has no form of currency. This has even led to debates about whether the artist intended the Smurfs as a metaphor for socialism. "The series wasn't just about sweet-looking dwarfs," said Alan Mechem of the British Smurf Collectors Club.He thought that Culliford wanted it to show things like equality and tolerance.
