Prep中的代词指代现象

刚做了一圈破解的prep sc，不知道大家有没有发现，prep中代词指代错误被极大的弱化了?

最明显的就是ceo 这道题，标准答案竟然是 C !!!! (就算有争议那也没辙了，gmac就这么判)

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.

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

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

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

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

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

我们之前用来排出，觉得有歧义的代词指代错误，在prep中好像都变得可以接受了. 我觉得是不是在不影响逻辑的基础上，不用太吹毛求疵，把歧义强加给别人。

我还有10天就考了，祝这个月的g友都能取得好成绩

这题是C吗。。。。lz可不可以解释一下。。。

代词真的被弱化了吗？我代词指代老错，对这个不敏感阿。。。

标准答案c  是prep系统自己给的

这道题其他选项都有点小问题，以前人们（包括新东方一些所谓的权威）一直认定是B，但b也确实有错误，不合逻辑啊

52.   (27251-!-item-!-188;#058&003145)

In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting East African cave paintings.

(D) Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of

(E) Leakey's contributions to archaeology include discovering the earliest direct evidence of hominid activity and painstaking documentation of

还不如这一道代词指代所有格奇怪呢，prep的代词指代好像没有形式平行重要。

另外，最近的破解版注解对指代也没有确定的说法，有时是就近指代对，有时是多个可能指代错，反正正说反说的都有，没法捉摸，不知有没有权威的说法。

1) which不能指代前面整个句子
2) both…and…结构一定要平行
(A) which不能指代句子；both…and 连接对象不平行，weaken by…与by…，应为weakened both by…
and by…
(B) Both concern about the government’s agreement…and the growing结构不平行,应该改为
concern both about the government’s agreement… and the growing; 整个句子缺乏主语; 该句用了

which--->A,B,E排除

For C, it has no reference

You have to chooce D coz this choice contains correct G construction and modifers. You don't need consider the referent for "its", and get the right answer, but if you consider the meaning of the pron and the whole sentence, you can unambiguously get the referent of "its" to "the country's currency".
