Many psychologists and sociologists now contend that the deliberate and even brutal aggression integral to some forms of competitive athletics increase the likelihood of imitative violence that erupts among crowds of spectators dominated by young adult males.

(A) increase the likelihood of imitative violence that erupts

(B) increase the likelihood that there will be an eruption of imitative violence

(C) increase the likelihood of imitative violence erupting

(D) increases the likelihood for imitative violence to erupt（E）

(E) increases the likelihood that imitative violence will erupt

请问为什么是E.  这里increase的主语是intergal吗? 那deliberate and even brutal aggression integral 是什么意思呢?

主语是aggression，

Many psychologists and sociologists now contend that （the deliberate and even brutal ）aggression（ integral to some forms of competitive athletics ）

括号里的都是修饰成分，修饰aggression
