Read the following article and select the best answer. Article: How can you hear your friends' voices when they are far away and you can't make a long--distance call? Besides the web camera system with your computer, we have a new high-tech way to solve the problem and ease your pain of missing them. The Japanese company Combiwith created a system-- . It makes people in pictures speak! The "talking picture" has a special pen. It is actually a pen-shaped scanner. It can scan information in special--made pictures. A connected player will then play the information out loud. First, you need to take a picture and record what you want to say with the company. The company will then make special barcodes onto your picture(you can't see those codes). Those codes are your voice and your words. When you hold up the pen to scan your picture with barcodes, a player connected to the pen will start to play. It plays things you've recorded. That way the invention makes the "you" in the picture speak! Do you want your friends and families talking out of pictures? Have them make pictures like that, and you can hear them whenever you want, only with the "talking picture" system. The system can play messages for up to 12 minutes. "The pictures would be useful for those who hope to hear the voice of someone living far away," said Mayumi Fuji, a spokeswoman for the company. "Grandparents, for example, longing to know about their grandchildren, would be happy to hear their voice when they see the picture," Fuji said. But it is troublesome to go to the company for taking a special picture first. And, it is much more expensive than using a telephone. The photo with barcodes costs between 17,040 and 17,990 yen (160 and 169 dollars). The larger picture you want, the more you pay. Now, just raise a finger, lonely people can have their loved ones speak out of pictures. But, whether the "talking picture" is practical or not, let's wait and see. Question: What is the attitude of the author? - Optimistic. - Uncertain. - Positive. - Pessimistic.

Q: Read the following article and select the best answer. Article: In Shanghai's Grand Theater, a fashionable, mainly young audience applauds enthusiastically as Guo Yong takes center stage.He holds a large bushy tree branch with leaves.Blowing on one of the leaves, he produces a sound like the singing of birds as he plays a traditional Buyi folk song.Some other musicians are also playing the traditional instruments from various ethnic groups in China. It's the first time such music has ever been performed in the Grand Theater.But all this is the efforts of Zhu Zheqin, a Cantoneseborn singer, who has made it her mission to help preserve China's traditional ethnic music. In 2009, after being appointed a United Nations Development Program ambassador, Zhu traveled through some of China's remotest regions in an attempt to document the traditional music of various minority groups.In the course of the fourmonth trip, she recorded more than a thousand songs.But she noticed that many of the best musicians were old, and some of the music was at risk of dying out. "I was shocked by the beauty of what I heard--it was so good," she says."But it needed support.I hope to let people see the beauty of these things in the contemporary times." So Zhu decided to introduce some of the musicians to a wider audience.By doing this, she hopes to rekindle the interest of the younger generation."Young people don't like this music much; they prefer pop music and love songs.They think these songs are something their grandma sings.This kind of repackaging gives young people a new door into their heritage." Zhu believes China needs to look again at its own roots."China today is basically all Western art; in our conservatories Western classical music is the top," she says."For China to really contribute to the world, we need to go on our own path.So what can represent China today?" The answer, she suggests, is to move from "made in China" to "created in China". Question: Which of the following is true of Zhu Zheqin? - She teaches music in a conservatory. - She is helping preserve Chinese ethnic music. - She works as an official in the United Nations. - She's created all the music for the Grand Theater.
A: She is helping preserve Chinese ethnic music.
