Input: Consider Input: 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.

Output: What does this text mainly tell us?

Input: Consider Input: Article: Today, traditional opinions about men still exist. A man has to be strong, brave, sports loving and manly. Anything less would not be considered manly. Sports such as football, basketball and boxing all tend to be men's sports. However, the dance of ballet is considered _ because it requires nice movements. This tradition is shown in the movie, Billy Elliot. Billy Elliot is a movie that protests against this traditional view of men. Billy Elliot is an eleven-year-old boy that has a natural talent for ballet dancing, but his father will not allow it. Billy's father wants him to take up boxing and become stronger, but Billy goes against his father's wishes and takes up ballet dancing. This difference of opinion makes Billy sad. What's more, his friends also laugh at him. After saving enough money, his father sends Billy to a weekly boxing course; however, Billy doesn't enjoy boxing because he always loses in matches and is often hurt. His ballet teacher, Mrs. Wilkinson thinks that men or women should not be judged by the activities they like to do, so she tells Billy's father that although he wants his son to make a good living, he should let his son do what he loves to do because he has a talent for it. When his father finally realizes the truth, Billy is surprised. In the end, with the help of his father, brother and all the people around him, Billy goes to the Royal Ballet Academy in London and becomes a very successful ballet dancer.
Answer: He loves ballet.

Output: Why is Billy laughed at by other children?

Input: Consider Input: Article: Without plant, people could not live. We eat plants. We breathe the oxygen that plants produce. And we need plants for another reason: we need them for their beauty. Imagine a world with no plants. Imagine no flowers with their sweet smells, their beautiful colors and their lovely shapes. Imagine when the wind blows, not being able to hear the leaves in the trees or watch the branches sway from side to side. Everywhere people need the beauty of plants. That is why we have parks full of trees and flowers. That is why people always try to design houses with room for some grass and a garden. Do you talk to your plants? Do you give them love and attention? Peter Tompkins and Christopher Bird, writers of a book called THE SECRET LIFE OF PLANTS, tell of an experiment in which two seeds were planted in different places. While the plants were growing, one plant was given love and hopeful ideas. The other plant was given only hopeless ideas. After six months, the loved plant was bigger. Under the earth it had more and longer roots; above the earth, it had a thicker stem and more leaves.
Answer: We need plants not only for food and oxygen but also for their beauty.
