问一道有关怪异所有格的PREP，132. (31556-!-item-!-188;#058&004545)

132.
   (31556-!-item-!-188;#058&004545)

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

我不太明白，CEO's 这里到底是CEO的复数？ 还是所有格表示？？？？？？？？？？

看答案倒推，觉得是复数，不应该是所有格吧？可是其表达方式就是所有格啊？

看这个版本的解释，CEO's 是CEO复数形式，以缩写字母组成的专有名词复数形式可以是加's或加s。

这个我也是看了才知道的。
