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: When elephants retire, many head for the Elephant Sanctuary in Hohenwald, Tenn. They arrive one by one, but they tend to live out their lives two-by-two. "Every elephant that comes here searches out someone that she then spends most all of her time with," says sanctuary co-founder Carol Buckley. It's likely having a best girlfriend, Buckley says - "Somebody they can relate to, they have something in common with." Debbie has Ronnie. Misty can't live without Dulary. _ But perhaps the closest friends of all are Tarra and Bella. Tarra, an 8,700 pound Asian elephant; Bella, a stray dog, are closest friends. Bella is one of more than a dozen stray dogs that have found a home at the sanctuary. Most want nothing to do with the elephants and vice versa. But not this odd couple. "Bella knows she's not an elephant. Tarra knows she's not a dog," Buckley adds. "But that's not a problem for them." "When it's time to eat they both eat together. They drink together. They sleep together. They play together," Buckley says. Tarra and Bella have been close for years -- but no one really knew how close they were until recently. A few months ago Bella suffered a spinal cord injury. She couldn't move her legs, couldn't even wag her tail. For three weeks the dog lay motionless up in the sanctuary office. And for three weeks the elephant held vigil: 2,700 acres to roam free, and Tarra just stood in the corner, beside a gate, right outside that sanctuary office. "She just stood outside the balcony - just stood there and waited," says Buckley. "She was concerned about her friend." Then one day, sanctuary co-founder Scott Blais carried Bella onto the balcony so she and Tarra could at least see each other. "Bella's tail started wagging. And we had no choice but to bring Bella down to see Tarra," Blais says. They visited like that every day until Bella could walk. Today, their love -- and trust -- is stronger than ever. Bella even lets Tarra pet her tummy - with the bottom of her enormous foot. They harbor no fears, no secrets, no prejudices. Just two living creatures who somehow managed to look past their immense differences. Take a good look at this couple, human beings. Take a good look at the world. If they can do it -- what's our excuse?
