 Q2: 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.

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

选E， the likelihood for....& the likelihood that....有啥区别啊，干嘛非要选THAT

Q3:  most nations regard their airspace as extending upward as high as an aircraft can fly    此句话什么意思啊？

1 句子的主干是 To speak is to instill

2 因为D中的likelihood可以和for imitative violence连 也可以和to erupt连 这种用法在GMAT中是被判定为错误的

3 多数国家认为他们的领空就是飞机能飞到的最高高度
