I did answer A originally, but let me explain why E is right.

A. on whether significant warming will occur and what impact will it have if it does.
'will it' is used in a question. Definitely wrong.
If this answer wrote 'it will' instead of 'will it', this would have been the correct answer.

B. on whether warming that occurs will be significant and the impact it would have.
'whether~ and impact' is not parallel.

C. as to whether significant warming will occur or the impact it would have if it did.
'on' or 'over' is preferred.

D. over whether there will be significant warming or the impact it will have.
'or' should be 'and.'
'whether~ and impact' is not parallel.

E. over whether significant warming will occur and what impact it would have.
The change of tense from will to would is justified as you can consider this a case of subjunctive mood.

My take is E

A. on whether significant warming will occur and what impact will it have if it does. - whether and if in a same sentence , already suspicious
B. on whether warming that occurs will be significant and the impact it would have. - meaning is changed , here the warming will occur for sure , also warming that occurs and the impact are 2 different things , here both are mentioned as one part

C. as to whether significant warming will occur or the impact it would have if it did. - or is a problem here, also if

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

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

+1 to E. I do not see how A can be right since it uses "will it" instead of "it will." Seems to me like "will it" should only be used when posing a question (I am sure there are some exceptions). I understand the skepticism with "would" in E, however, I did not like any of the other answers. I chose E because I thought it was less incorrect.

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

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.

Idioms "divided over " and "divided as" are incorrect.
"divided on" is correct.

Of A and B, I would choose A.

IMO A.
E has change in tense from will...would.

Any thoughts.

I agree with A.

would is incorrect in this context. Also, other options are awkward because of 'divided as to' and 'divided over'

Both 'decide on' and 'decide over' are correct.

@jj22l, you're right that the construction "will it" should be used to ask a question, and isn't appropriate as it appears in answer choice A.

@scheol79, you're right that answer choice E is an unusual example of the subjunctive mood, which can be used to express hypothetical situations. You'll often see "would" used to express the result of a hypothetical condition:

If the two companies merged, the resulting corporation would be unstoppable.
If I were richer, I would buy a yacht.

Not sure what the source of this question is -- to be honest, none of these choices is really ideal, and as I mentioned the use of the subjunctive in this context is a bit unusual. But E is the best of the bunch.

Hope that helps!

Hi Jen,

Good to see you!

Besides that...isn't the idiom 'divided on' incorrect? I thought 'divided over' is the correct idiom which left me with D/E ... i preferred E because D tends to change the meaning of the sentence...also 'or the impact it would have' sounds awkward too...

Hi guys can someone confirm the OA. Between A and E i choses E as 'divided over' i feel is the correct idiom but even divided on is fine.
