Traffic safety officials predict that drivers will be equally likely to exceed the proposed
speed limit as the current one.
A. equally likely to exceed the proposed speed limit as
B. equally likely to exceed the proposed speed limit as they are
C. equally likely that they will exceed the proposed speed limit as
D. as likely that they will exceed the proposed speed limit as
E. as likely to exceed the proposed speed limit as they are
答案是E，但是为什么？as they are the current one 是省略了什么吗？
因为one如果是指limit的话，they是指drivers，如果这样，那不是说司机是速度限制，可是我理解不应该是说司机在这样的速度限制下吗？likely to exceed the proposed speed limit是两个AS中间的内容，那AS...AS...是右边的和中间的内容也并不平行？
