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
困惑：B项为什么不对呢？ “a ratio that compares to 42 times”里面的“a ratio"不能理解成是前面句子中的”"419 times"吗？这样不就是两个比率在对比吗？
C项中的“their”难道不存在指代不明的问题吗?
坐等大牛点拨！

their还能指代神马？

their 可以指代CEO's,也可以指代blue-collar workers，这样不就出现歧义了么？
