Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

During the teenage years, many young people can at times be difficult to talk to. They often seem to dislike being questioned. They may seem unwilling to talk about their work in school. This is a normal development at this age, though it can be very hard for parents to understand. It is part of becoming independent of teenagers trying to be adult while they are still growing up. Young people are usually more willing to talk if they believe that questions are asked out of real interest and not because people are trying to check up on them.

            Parents should do their best to talk to their sons and daughters about school work and future plans. However, it is not a good idea that parents push teenagers to talk if they do not want to. Parents should also watch for the danger signs: some young people in trying to be adult may experiment with sex, drugs, alcohol, or smoking. Parents need to watch for any signs of unusual behavior which may be connected with these and get help if necessary.
