单项选择题
A 15-year-old boy is admitted to the health care facility after acting out his aggressions inappropriately at school. Predisposing factors to the expression of aggression include which of the following（）
A. Violence on television.
B. Passive parents.
C. An internal locus of control.
D. A single-parent family.
答案
参考答案：A
解析：
Violence on television has been correlated with an increase in aggressive behavior. Passive parents contribute to acting-out behaviors but not specifically to violence. An internal locus of control leads to a positive sense of self-esteem and isn’t related to violence or aggression. There is no direct correlation between single-parent families and violence.
