212. (GWD-10-Q1)According to a survey of graduating medicalstudents conducted by the Association of American Medical Colleges, minoritygraduates are nearly four times more likely than are other graduates inplanning to practice in socioeconomically deprived areas.
A.      minoritygraduates are nearly four times more likely than are other graduates in planning to practice
B.      minoritygraduates are nearly four times more likely than other graduates who plan onpracticing
C.      minoritygraduates are nearly four times as likely as other graduates to plan onpracticing
D.       it is nearly four times more likely thatminority graduates rather than other graduates will plan to practice            (C)
E.       it isnearly four times as likely for minority graduates than other graduates to planto practice
此题PREP 解释A选项：
A.     主系表结构的比较中，如果是主语比较，系动词要省略，are多余；be likely in doing用法错误，应为be likely to do…
但是后面又附上白勇语法：

1)      比较从句连系动词be与主句连系动词be相同，可以省略be，也可以不省略。
请问，这个不是矛盾吗？ 应该A选项中are是可有可无的，不能算错误点啊。求教！
