A few years ago it was popular to speak of a generation gap, a disagreement between young people and their elders.Parents said that children did not show them proper respect and obedience , while children complained that their parents did not understand them at all.What had gone wrong? Why had the generation gap suddenly appeared? Actually the generation gap has been _ for a long time.Many people argue that a gap is built into the fabric of our society. One important cause of the generation gap is the chance that young people have to choose their own ways of life.In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and agree to, and to continue the family occupation .In our society, young people often travel great distances for their education, move out of the family home at an early age, marry or live with people whom their parents have never met, and choose occupations different from those of their parents. In our easily changing society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do.Often, however, the strong desire that parents have for their children are another cause of the disagreement between them.Often, they discover that they have very little in common with each other. Finally, the speed at which changes take place in our society is another cause of the gap between the generations.In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date overnight.The young and the old seem to live in two very different worlds, separated by different skills and abilities. No doubt, the generation gap will continue to be a feature of American life for some time to come.Its causes are rooted in the freedom and changes of our society, and in the rapid speed at which society changes. Which of the following statements is true according to the passage? A) Parents should be strict with their children. B) The younger generation should value the older generation for their wisdom. C) The generation gap is partly caused by the older generation. D) The generation gap does not exist in American society.

*Question*
In Kenya, educational and career opportunities are almost non-existent for people born with physical challenges. They face many forms of discrimination -- including beliefs that their condition was caused by a curse. But one father whose son Brain was born deaf, mute and blind aims to change all that. Joseph Shiroko started a school four years ago that teaches students who can not hear, speak and who have very low or no vision a wide range of skills to support themselves. The baby clothes the students knit are well known in the local community. And the school has developed a reputation for its dried smoked meat products. Brain Resource Center, a boarding school, teaches deaf and blind young Kenyans from across the country a variety of skills they can use to earn a living. "We have a number of philosophies that inform what we are doing: accepting these people; loving them; giving them opportunities." said founder Joseph Shiroko. Teachers, most of whom are graduates from the school or are themselves physically challenged, work with students. Mary Kerubo, 22, has a passion for knitting sweaters, which she plans to continue in her village. "I feel comfortable here because Sween -- my teacher understands me," said Kerubo. "Even if I do not see well, she always repeats her lessons again and again so that I may understand how to make sweaters. I know I will make it." Kerubo's teacher, Sween Lyaka, was among the first graduates of Brain Resource Center four years ago. She says her students have a lot of unrecognized potential. Sween says in the future, she plans to purchase four sewing machines that she will use to teach students and produce and sell sweaters in her home village. The center also works with students' families to set up projects that will continue after the students graduate. Founder Joseph Shiroko's son, Brain, was the inspiration behind Brain Resource Center.
