Dear pkhats,
I'm happy to help. :-)

First of all, this is a classic if/whether split. For a yes/no question, the answer to which is unknown, we always use "whether", not "if." We would use "if" for a conditional --- "If a share doesn't rise, then ..." That's not the case here. Choice (B) is wrong. See:
http://magoosh.com/gmat/2012/gmat-sente ... s-whether/

Second, on the GMAT, "whether ... or not" is an abomination. This is a common construction in American colloquial English, used for clarity in spoken language, but in the formal environment of the GMAT, this construction is wrong. The words "or not" make the sentence longer and add absolutely zilch to the meaning. Anything that makes the sentence longer without adding additional meaning is 100% wrong on the GMAT. For this reason, choices (A) & (C) & (D) are wrong.

Thus, the only possible answer is (E).

This question is not very well designed. It falls short of the high standards maintained in the GMAT.

Does all this make sense?
Mike :-)

mikemcgarry does this rule regarding to "whether .... or not" still apply?

I have seem some excercises that the correct answer had it.

I see "E" as the correct answer just because it is more concise.

Could you provide further explanation regarding to this rule?
