Teacher: Now, understand the problem? If you are still confused, see the following 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.

Now, solve this instance: Article: One rainy evening I went to fill up at the gas station. A pre-teen boy approached my car and asked me for money to help him and his mother stay in their hotel for an additional week. He stated that if they did not come up with $25 they would be _ that same evening. Having worked in social services before and having doubt about this, I asked why his mother hadn't applied for social services for assistance. The boy said that they needed to remain in their hotel for one more week until his grandmother, who lived out of town, could take them in. I gave the boy what I had -- $5. He thanked me and continued to wander the parking lot asking for help. I got my gas and drove away. Some weeks ago, a boy asked me for money and I told him I didn't have any though I did. Yet, I thought about it for a while and went looking for the boy to give him a dollar. But it seemed that he had disappeared into thin air. "This time," I thought, "I'll do it differently." I went to my bank and got an additional $20, then I returned to the gas station. The boy was still there. I observed him shyly approaching strangers who walked past him without notice. I pulled up and waved at the boy to come over. I handed him the $20 bill. He reached through my car window and gave me a huge hug. His hug told me all I needed to know -- that finally this kid could get out of the rain, the cold and the darkening skies and go inside where it was warm.
