One 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: Article: When Marco Polo travelled to Hangzhou, China 700 hundred years ago, never had he thought he'd be creating a job of social media ambassador in the 21st century in China. On May 20, one lucky foreigner would be selected to become the modern-day Marco Polo, getting a free 15-day trip to the scenic city of Hangzhou in China, and rewarded $55,000 in the next year for working part-time to promote the city to the global audience. Five finalists from Australia, Romania, U.S., Switzerland and France were in the final race. They came from a pool of 700 applicants from around the world, carefully selected by the Hangzhou Tourism Commission on their familiarity with China, social media presence and adventurous spirit. Located about 100 miles southwest to Shanghai, Hangzhou is home to 844 million population and among China's richest cities as measures by per-capita GDP. Traditionally, Hangzhou is known for its charming West Lake, a UNESCO world heritage site with traditional Chinese stories and tales, and the Grand Canal, which travels from Hangzhou to Beijing and was a key route of transportation in ancient China. The city's mild climate and charming environment drew 97 million tourists last year, contributing to 6.5% of the city's GDP. The lucky winner would start an all-expense-paid trip to Hangzhou, which, in addition to visits to tourist sites and tastings of delicious food, also would include a four-day ride along the Grand Canal and three evenings spent at a local resident's home. "It is in fact a part-time job. How you work that out efficiently is your problem," Liam Bates, perhaps the strongest competitor because of his fluent Chinese, said. "We will see how hard it is to meet these numbers."
Answer: attract more foreign tourists to China

The purpose of Hangzhou choosing a social media ambassador is to _ .
