再问gwd１-１７

A recent review of pay scales indicates that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times in 1980.

A.      that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

B.       that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

C.      that, on average, CEO’s now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

D.      CEO’s who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

E.       CEO’s now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

 我想在Ｃ中their会不会有指待不明的错误啊？

其实我也有想过这个问题,但是语法里面说 代词一般有先指代最靠近的一个名词,所以句子里面靠THEIR最近的是BLUE-COLLAR WORKERS,所以THEIR的指代没有什么太大的问题. 

其实指代的歧义我觉得是 代词在句子中可以解释两个不同的事物 (两个都有意义),此时代词会有指代问题,如果一目了然知道指代哪个,歧义就不是考试的重点了.

这些只是个人看法,还要请牛牛指正!
