Article: Do you like listening to music? Do you often turn up the music when you're using earphones? If so, your hearing may have been damaged . The World Health Organization (WHO) is worried that 1.1 billion children and young people are damaging their hearing by listening to loud music. Nearly half the young people in developed countries may lose their hearing because of the "unsafe use" of music players, including smartphones. Loud music in nightclubs, parties and at sports also make it worse. The WHO advises young people to listen to music for just one hour a day. Dr. Etienne Krug told BBC: "What we're trying to do is to draw people's attention to a problem that is not talked about enough." He said it's easy to solve this problem. Dr. Krug said keeping the music down and limiting the listening time to less than one hour a day would save a lot of people's hearing. However, he also said, "Even an hour can be too much if the music is too loud." Ralph Holme, a researcher, explained how loud noise can damage ears. He said: "Loud sounds damage your hearing by killing off thousands of little hair cells in the inner ear. The cells can tell different sounds through vibration . But they are very _ --they get damaged easily and even die if they vibrate too much because of loud sounds for too long." He warned: "The bigger problem is they don't grow back and the ear can no longer get sound." No one wants to lose their hearing! Therefore, next time when you listen to music, make sure it's not too loud and only listen for less than an hour. You can enjoy your music much better in this way. Question: From the passage we can learn that _ . Yes or no, is the answer "keeping the music down would save young people's hearing"?
No

Article: The workers who brought the girl to the orphanage knew little about her. The street where they found her had been her home for many years. Her parents were unknown. They left her long ago. At the orphanage, the girl, like all the children there, was taught to read and write. While she was studying at the orphanage, she learned something else-to be independent . At twenty-one, she left the orphanage and began to work as a secretary. And then, in 1975, while she was still working as an ordinary secretary, something special happened. She entered the Miss Hong Kong Competition and won it. This was the turning point in her life. Now her name, Mary Cheung, was known to everybody. Mary entered the competition because she wanted to show that orphanage girls could be something. Winning the competition gave her the chance to start a new life. This led her first into television and then into business as a manager. When she was working as a manager, she had trouble with her reports. "My English just wasn't good enough." she says. Luckily, she had a boyfriend (who later became her husband) to help her. Mary studied management at Hong Kong Polytechnic and graduated in 1980. She started her own business in 1985. But she did not stop developing herself. She then studied at the University of Hong Kong. Since 1987, she had spent a lot of time on photography . She has held several exhibitions of her works in many places-China, New Zealand and Paris. She still found time, however, to work on TV, write for newspapers and support her family. The girl from the street has come a long way, but her journey has not finished yet. Question: Before Mary Cheung was brought to the orphanage, _ . Yes or no, is the answer "she had lived in the street for many years"?
Yes
