Experts agree that adolescence is normally a period when serious problems develop.

I believe growing up in this day and age is more difficult than growing up in the 1980's and 1990's. Kids now have to deal with many normal aspects of growing up, and they have to deal with the techonologies that make it even more difficult. Every adult has been through the adolescent growing stages. This includes dealing with growth spurts, voice changes, skin issues, and the normal hormonal changes. How they learn to deal with these changes or in some cases NOT deal with them, will and can ultimately shape the adult they become.

I believe that the answer in this question is FALSE. Expects didn't agree that the period of adolescence is normally a period when serious problems are develop rather it is the period where girls will have menstrual period, growth of hair in under-arm and some other periods and also for the boys their body will build up and have muscles.

The answer would be true.

Well, l think that some effective communication is, emotional barriers and lack of attention, interest distraction or irrelevance. also some physical disabilities such as hearing problems or speech difficulties.      l hope i am correct  and you good luck.
