11. Some psychiatric studies indicate that among distinguished artists the rates of manic depression and major depression are ten to thirteen times as prevalent as in the population at large.

(A) the rates of manic depression and major depression are ten to thirteen times as prevalent as in

(B) the rates of manic depression and major depression are ten to thirteen times more prevalent than in

(C) the rates of manic depression and major depression are ten to thirteen times more prevalent when compared to

(D) manic depression and major depression are ten to thirteen times as prevalent when compared to（E）

(E) manic depression and major depression are ten to thirteen times more prevalent than in

除了prevalent的错误.

我想问A是不是少个those?  这个those是不是必须的??? 可不可以理解为:the rates of....are ten times as....as(they are) in ... 省略相同的主语谓语,就不用加those了..

可以吗? 谢谢指点

A不是少those,A是主语不对！请楼主注意，A,B,C的主语是rates,那么就是说the rates are ten to thirteen times more ... than,这个逻辑有问题，rates怎么prevalent?rates怎么in the population? 做语法题目还是要看中心词，这是关键。所以这里不是比较的问题，而是逻辑主语问题

省略是为了简洁，而补出是为了排除歧义。

不会引起歧义的相同成分就要省略。
