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

对于答案没有疑问，我想问的是what impact it would have这个名词性从句，the thing which impact it would have, 那么这个impact是what名词性从句中的动词，要是impact是名词的话，怎么去理解这个what名词性从句？ 谢谢NN.

把那个从句单独拿出来看，如果想问某某的影响是什么，一般都会说what impact will it have
what是特殊疑问句的引导词，impact是这个疑问句的宾语。
特殊疑问句做从句的话，只需要调整一下语序。

我是这么理解的。。。。

看我那么理解你的话对不对 over whether significant warming will occur and what impact it would have中, over介词后面要加名词做宾语,所以whether是引导名词性从句,连词and,暗示what也要是名词性从句,如果是what impact it would have, the thing (which impact) it would have 中,which impact 做would have的宾语,请指教,谢谢阿
