13 Read the text and choose the appropriate answer.

A child who gets ill or has an accident can miss weeks or months of school. Which may mean having to repeat the whole year.

Now there is a special telephone system to help children keep up with their studies, while they recover from their setbacks. The system is called Tele-Class. And it`s working in lots of places. In Oakland, California, for example, all the child needs is a telephone, a headset, the right textbook, and a specially trained teacher like Mrs.Molly Steele. Mrs.Steele used to teach regular elementary school. But now she has a class of ten children. Some ill at home, some in the hospital.

Every day she inserts a card into a special telephone and dials her students. Once they are all on the line, class begins. Not only Mrs.Steele can talk to the children, but they can talk among themselves. So they get a classroom atmosphere complete with discussions and question-and-answer sessions. They get 20 hours a week of education they would have missed before.

А) learning is fun.
