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: Mary Allen was my best friend- like the sister I ever had. We did everything together : piano lessons, movies, swimming, and horseback riding. When I was 13, my family moved away. Mary and I kept in touch through letters and we saw each other on special occasions- like my wedding and Mary's. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back stamped "Address Unknown". Over the years, I thought of Mary often. I wanted to share stories of my children and then grandchildren. And I needed to share my sorrow when my brother and then mother died. There was an empty place in my heart that only a friend like Mary could fill. One day I was reading the newspaper when I noticed a photo of a young woman who looked a lot like Mary and whose last name was Wagman- Mary's married name. "There must be thousands of Wagman. "I thought, but I wrote to her anyway. She called as soon as she got my letter. "Mrs Tobin!"she said excitedly. "Mary Allen Wagman "is my mother. Minutes later I heard a voice that was recognized instantly, even after 40 years. We laughed and cried and caught up on each others lives. Now the empty place in my heart is filled. And theres one thing that Mary and I know for sure: We don't lose each other again.
