请教一道比较题

1.        According to a survey of graduating medical students conducted by the Association of American Medical Colleges, minority graduates are nearly four times more likely than are other graduates in planning to practice in socioeconomically deprived areas.

(A) minority graduates are nearly four times more likely than are other graduates in planning to practice

(B) minority graduates are nearly four times more likely than other graduates who plan on practicing

(C) minority graduates are nearly four times as likely as other graduates to plan on practicing

(D) it is nearly four times more likely that minority graduates rather than other graduates will plan to practice（C）

(E) it is nearly four times as likely for minority graduates than other graduates to plan to practice

请问A中抛开其他的错误,这个than are other graduates中的are是不是需要的呢?到底是比较minority graduates 和 other graduates还是比较他们两者的动作,即are likely to plan on practicing?

请问有没有关于比较结构的总结可以参考呢?

这种比较题最好做了...一看到几倍的...比如 four times....three times...后面一定跟 as...as...,跟more than..或THAN...就肯定错..看都不用看就要排除!
