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
OA is __E__.
In choice E, are "whether significant...occur" and "what impact...have" noun phrases? According to the structure of the sentence, they must be noun phrases because they come after a preposition (over), and only noun and noun phrases can follow a preposition.
However, both don't seem noun phrases:
Can "whether + clause" be a noun phrase?
Also, I cannot identify what kind of structure "what impact it would have" is. It seems a clause. Is "what" working as a pronoun in this sentence? :s
Finally, they don't seem parallel at all, but "AND" requires parallelism.
Please, your comments.
