Q: Article: Born with easy-broken bone disease, Zhang Yonghong is only half a meter tall and must use a wheelchair. His thin arms and legs can hardly support any weight, and he is unable to take care of himself. However, his hands are able to produce fine paper-cuts, which will free his daughter from the same disease. To support himself, he learned how to make paper-cut art from his mother. He sold his artwork and taught his techniques in Xi'an for eight years before discovering his young daughter _ the disease from him, leading Zhang to move his family to Beijing for his daughter's better treatment five years ago. The daughter's treatment costs about 30,000 yuan a year. The family's savings was used up in two years, and Zhang was forced to start to sell his work in underground passages with his healthy wife, who soon left him because of the hard life. With a little help from government, he was lucky to meet some kindhearted people in Beijing. A Hong Kong businessman gave 60,000 yuan to him last year to treat the girl and start a small shop on Qiangulouyuan, which is known as a famous hutong that attracts lots of tourists over holidays. Zhang Rui, a university graduate, spends most of her time helping Zhang sell the paper-cuts, translating the stories of the paper-cuts into English and selling the works on the roadside of Nanluoguxiang. However, the artist still lives beyond his income and struggles to continue his small business. "Selling paper-cuts is his only source of income. Without this, he can't support the family and treat his daughter," says Zhang Rui, who hopes more people will help Zhang.
Answer: His easy-broken bone disease affected him.

A: Why did Zhang grow only half a meter tall?

Q: Article: Buster Brown was a thief and a good one too,he thought. He'd never been caught by the police because he never took chances.He was always prepared for any unforeseen event or emergency. Confidently,he stood outside the house of his intended victim and read the sign on the front gate of the house."Don't worry about the dog--be aware of the owner!" it said.Buster smiled and found his way in. The house looked quite normal outside,but inside it was very exotic with fascinating objects on display.As he began putting them into his bag,a dog came into the room.It stopped when it saw Buster,then wagged its tail madly and went over to him,licking his outstretched hand. "Good boy," Buster whispered. "What a great guard dog you are--trying to lick me to death." Satisfied he'd made friends with the dog,Bluster began to wander round the house,choosing items to put in his bag.His skilled eye picked out only the best antiques :a pair of silver candleholders,a silver tea-and-coffee service,etc..His new friend,the dog,sat and watched,as if wondering what was happening. "Well,boy," Buster whispered,finally."That might do.Any more and I won't be able to carry it!" He swung the heavy bag onto his shoulders, just as the lights came on, nearly blinding him. He shielded his eyes with his hand. "You're a very silly person," the figure in the doorway said, his voice dry and dust. As the man came closer, Buster could see he was well dressed. His face seemed familiar, but Buster couldn't quite place where he had seen him before. "You should have taken more notice of the sign outside," the man rasped. "I knew about this attempted robbery last week and I also know you will end up behind bars for 20 years. Fancy trying to rob the house of the world's greatest fortune-teller!"
Answer: He had never been caught by the police.

A: Why was Buster so confident?

Q: Article: I'm not so sure I like my friends any more. I used to like them-to be honest. We'd have lunch, talk on the phone or exchange emails, and they all seemed normal enough. But then came Face Book, and I was introduced to a sad fact: many of my friends have dark sides that they had kept from me. Today my friends show off the more unpleasant aspects of their personalities via FaceBook. No longer hidden, they're thrown in my face like TV commercials -unavoidable and endless advertisements for the worst of their personalities. Take Fred. If you were to have lunch with him, you'd find him warm, and self-effacing .Read his FaceBook and you'll realize he's an unbearable, food-obsessed boring man. He'd pause to have a cup of coffee on his way to save a drowning man-and then write about it. Take Andy. You won't find a smarter CEO anywhere, but now he's a CEO without a company to run. So he plays Mafia Wars on FaceBook. He's doing well-level 731. Thanks to FaceBook, I know he's playing about 18 hours a day. Andy, you've run four companies-and this is how you spend your downtime? What happned to golf?What happened to getting another job? Take Liz. She is positive that the flu vaccine will kill us all and that we should avoid it. And then comes Chris who likes to post at least 20 times a day on every website he can find, so I get to read his thoughts twice, once on FaceBook and once on Twitter. In real life, I don't see these sides of people. Face to face, my friends show me their best. They're nice, smart people. But face to FaceBook, my friends is like a blind date which goes horribly wrong. I'm left with a dilemma. Who is my real friend?Is it the Liz I have lunch with or the anti-vaccine madman on FaceBook? Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standard?
Answer: Chris

A:
Who is opposed to the flu vaccine in the text?
