GWD1-Q7:

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

这题思路是，indicate后应该加that,故排除D,E;比较结构419 times more pay than错误排除A

问题是B和C，james说过as+过去分词，as是指代的，在C里面指代的是前面整个的部分？

B和C有什么区别，老师看看！在一个就是看看我这题的思路对么？
