How should companies select young people for educational projects？ (Why？ / Why not？)

These crimes are not usually committed by people who are poor or in need. Young people often dislike and hate the adult world. They will do things to show that they are rebels. Also in Britain today it is easier for young people to commit crimes because they have more freedom to go where they like and more money to do what they like. There are two other possible causes which are worth mentioning. More and more people in Britain live in large towns. In a large town no one knows who anyone else is or where they live. But in the village I come from crimes are rare because everyone knows everyone else. Although it is difficult to explain, I think the last cause is very important. Perhaps there is something with our society which encourages violence and crime. It is a fact that all the time children are exposed to films and reports about crime and violence. Many people do not agree that this influences the young people, but I think that young people are very much influenced by the society they grow in. I feel that the fault may be as much with our whole society as with these young people. 6. From the passage we know that many British people are confused about ().
