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.

Solution: Researchers did experiments on kids in order to find out _ .
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

Problem: Article: Zhoukoudian is a small village situated about 50 kilometers to the southwest of Beijing. In the 1920s, archaeologists discovered some prehistoric human bones there which changed people's view of China's history. They came from an unknown species of man and were the first evidence of human life in China thousands of years ago. The remains were three teeth! In 1929, a complete skull was also discovered. Eventually, archaeologists found almost 200 items, including six skulls and more than 150 teeth. These discoveries proved the existence of a human species who lived in the area between 700,000 and 200,000 years ago. Four sites where Beijing Man and his relatives lived were discovered on the northern face of Longgushan. They lived in the caves in the area. However, the life span of Beijing Man was short. About 70% of the people probably died before the age of 14. Fewer than 5% lived to the age of 50. Ashes were found alongside the fossils which showed they had used fire for cooking food and also for light, warmth, and protection against wild animals. This is the earliest evidence of the use of fire anywhere in the world. They also made tools of bones and stones. Unfortunately, when Japan invaded China in 1937, excavations at the Beijing Man Site stopped and most of the fossils disappeared, including a Beijing Man skull. After the People's Republic of China was established in 1949, the work started again. Zhoukoudian was listed as a World Heritage Site in December 1987. It has not only given us important information about prehistoric Asian societies, but also provided amazing evidence about the process of evolution. Today, parts of the caves have been badly affected by rain. Some areas are almost completely covered in weeds, causing serious damage. Pollution from the nearby factories has also led to the problem. This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness of protecting it.
