1. Many psychologists and sociologists now contend that the deliberate and even brutal aggression integral to some forms of competitive athletics increases the likelihood that imitative violence will erupt.

D. increases the likehood for imitative violence to erupt

该项为什么不对呢？是不是没有这种搭配？

2. Consumer and producer prices have been rising, as have interest rates.

不是as应加句子么？还是这是一个省略句倒装？

3. Byron possessed powers of observation that would have made him a great anthropologist and that makes his letters as a group the rival of the best novels of the time.

A. makes his letters as a group the rival of

B. makes his letters as a group one to rival

C. makes his letters a group rivaling

D. make his letters as a group the rival of

E. make his letters a group which is the rival of

that应紧跟修饰词，那后句并列that指代的不是observation(单数）么？为什么是make啊？即使是make,固定搭配应是make sth. sth. 或make sth. adj.,怎么变成了make sth. as?

Consumer and producer prices have been rising, as have interest rates.

应该是个倒装句噢

3 還是make sth sth.
make (his letters as a group) (the rival of...)

是个并列吧...

Byron possessed powers of observation that......and that...

也不是很懂，望更深层次的分析

that 可跳跃修饰

that修饰powers

在A OF B的结构中，修饰A或者B都是可以的
