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
Plz. explain

IMO E
A. on whether significant warming will occur and what impact will it have if it does.
The scientific community is divided on 2 questions X and Y. Hence X and Y should be parallel.
'whether significant' is parallel with 'what impact' However 'will occur' and 'will it have' are not parallel.
B. on whether warming that occurs will be significant and the impact it would have
'Whether warming' and 'the impact' are not parallel. Plus the issue is not whether the warming will be significant. This sentence is very awkward and changes the meaning.
C. as to whether significant warming will occur or the impact it would have if it did
'whether significant' and 'impact it' is not parallel. Also the scientific community is divided over 2 issues so we need 'and' and not 'or'.
D. over whether there will be significant warming or the impact it will have
Same problem as C
E. over whether significant warming will occur and what impact it would have
'Whether significant' and 'what impact' are parallel. Even 'will occur' and 'would have' are parallel.

Received a PM asking me to reply, specifically as to the "would" vs "will" stuff.
I agree: E on this one. The author's indicating a state of not-quite-sureness about this whole warming thing. He expresses this in two forms:
1) whether something will happen
2) what impact if would have if it did happen
Both constructions (notice the italics) indicate some kind of future uncertainty - either "whether... will" or "would."
Both of the things the sentence is discussing should properly indicate future uncertainty - that's the point of the sentence, right? So you could use "would" twice" or "whether... will" twice, but they chose to do one of each in the correct answer here.
We can eliminate A and D for the above reasons.
Next, the scientists are debating both of these issues, not one or the other, so we want "and," not "or." Eliminate C (and D, again).
Because the scientists are concerned about both of these issues, those issues should be presented in parallel.
B uses "whether" and "the impact" to introduce the two things.
E uses "whether" and "what" to introduce the two things.
E wins.
Re: the divided on / divided over thing. I think the original idiom was "divided over" but "divided on" has become quite pervasive in the language, enough so that I would have expected even GMAC to accept it. I wish GMATPrep had explanations so that we could read their rationale.
I'm least enthusiastic about that last one. I've seen better questions, overall. (And, annoyingly, I think this one is GMATPrep...)

No priority. Both are OK in this context.Shridharvk wrote:Which is the correct idiom to use?
