[Q]: Article: Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
Answer: People know little about their personalities.

[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: As one approaches some crossroads, one comes to a sign which says that drivers have to stop when they come to the main road ahead. At other crossroads, drivers have to go slow, but they do not actually have to stop (unless, of course, there is something coming along the main road); and at still others, they do not have either to stop or to go slow, because they are themselves on the main road. Mr. Williams, who was always a very careful driver, was driving home from work one evening when he came to a crossroads. It had a "Slow" sign, so he slowed down when he came to the main road, looked both ways to see that nothing was coming, and then drove across without stopping completely. At once he heard a police whistle, so he pulled in to the side of the road and stopped. A policeman walked over to him with a notebook and pencil in his hand and said, "You didn't stop at the crossing." "But the sign there doesn't say "Stop"," answered Mr. Williams. "It just says "Slow", and I did go slow." The policeman looked around him, and a look of surprise came over his face. Then he put his notebook and pencil away, scratched his head and said, "Well, I'll be scolded. I am in the wrong street!"
Answer: At some crossroads, drivers needn't stop or go slow.
