标题: PREP2-47

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

(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

句子结构：Those… argue that … data are an… means of… and point out that….

并列的that宾语从句，divide over后跟并列宾语whether… and what…。

(E) 正确，虚拟语气would+动词原形have，表对将来的假想，it指代significant warming。

为什么虚拟只虚拟AND后面的半句？？

前半句whether gloabal warming will occur是指是否会发生气候变暖，这是不需要虚拟的
后半句是what... would have,省略了if global warming occurs的一个假设，所以当然要用假设语气了
