[单项选择]It seems that our society favors a kind of ritualized aggression. Everywhere you look, in newspapers and on television, issues are presented using the terminology of war and conflict. We hear of battles, duels and disputes. We see things in terms of winners and losers, victors and victims. The problem is society’s unquestioning belief in the advantages of the debate as a way of solving disagreements, even proving fight from wrong.
Our brainwashing begins early, at school, when the brightest pupils are co-opted onto the debating team. The training in this adversarial approach continues at our tertiary institutions.

A. Kids are out of control because of their aggressive nature.
B. Kids may become disobedient when parents appear aggressive.
C. The wiser the kid is the more successful debater he would be.
