救命prep_93!!何解？

93. Those skeptical of the extent of global warming argue that short-term temperature data are an inadequate means of predicting long-term trends and point out that the scientific community remains divided on whether significant warming will occur and what impact will it have if it does.

A.       on whether significant warming will occur and what impact will it have if it does.

B.       on whether warming that occurs will be significant and the impact it would have

C.       as to whether significant warming will occur or the impact it would have if it did

D.      over whether there will be significant warming or the impact it will have

E.       over whether significant warming will occur and what impact it would have

我选e?

A：后半句的impact其实是一个虚拟语气，因为它的基础是在前半句成立之上的，因此不能和前半句时态一致。

B：warming that occurs罗嗦

C：as to后面没动词

D：there will be。。。or。。。

E：correct
