Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school. And, by the time that the average child finishes high school, he or she will have spent 18,000 hours in front of a television set as opposed to 12,000 hours in a classroom.
Parents are concerned about these figures. They are also concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Even if it is unreal--a cartoon cat beating up a cartoon mouse with a baseball bat--this violence may have a negative effect on the young minds exposed to it. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.

A. parents are strongly opposed to children watching TV
B. a cartoon program is not harmful if it is not real
