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 poaching ,or illegal killing,of rhinos in South Africa is growing worse each year.The government recently reported that a record number of rhinos were poached in 2015,a year which had more rhino killings in South Africa than ever before. The World Wildlife Fund,or WWF,says about 20, 000 rhinos live in South Africa. That is more than 80 percent of the rhinos in the world. Edna Molewa, South Africa's Environment Minister,says, "During 2015,we are sad to say this,1, 215 rhinos were killed.This is a rise in the number of poached rhinos from 1,004 in 2014 and indeed very worrying." The animals are hunted for their horns .Many people in Asia believe the horn has curing power, which drives poachers, at all costs, mad for more horns. But there is no scientific evidence for this belief.The horn is made of keratin .That is the same thing as human hair,fingernails and toenails. Ms.Molewa said 386 suspected poachers were arrested last year,an increase from the year before.But rhino protection workers say poachers often go unpunished after arrest. South Africa's legal system is ineffective. Ms. Mo1ewa said more needs to be done and South Africa is taking strong measures to protect rhinos.The efforts include moving some of the animals to secret places in neighboring countries. "Now approximately 100 rhinos have been moved to neighboring states in the SADC region during 2015 and 200 more rhinos will be moved this year," Molewa said. Jo Shaw,the rhino program manager at the WWF,said,"We're talking about a loss of a hundred rhinos a month,or more than three a day.We really need to see effective action not just at a national level but internationally." She says officials should find the criminal groups responsible for the poaching and punish them. Government officials are to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade.
