The correct answer should be D. Since the confusion is between D and E, I will focus compare these two choices only.caakash1430 wrote:Looking at all posts i m still confused on the answer...
What is the correct answer...D or E?
D Clearly adds Tongue as an extra piece of info not mentioned in Original sentence shouldn't it be discarded???
e. The reason that certain spicy foods, such as the Habanero pepper, make some people sweat is because they contain a chemical that stimulates the same nerves in the mouth as does a rise in temperature.
E is incorrect because of redundancy issue. E uses the structure - The reason for xyz is because abc. Clearly this is incorrect because the reason is not because of abc. The correct construction is:
1: xyz is because of abc. OR
2: the reason for xyz is abc.
Choice D corrects this error and uses the second construction. Now you are correct in saying that "on the tongue" is introduced in choice D. However, I believe this is really a typographical error. Most likely when the writers were creating this question, they may have included "on the tongue" in all the answer choices in some previous versions. But as they revised their questions, they may have missed to delete this from this choice D. GMAT typically never introduces errors in SC by introducing a new phrase in one of the choices. It may reword complete sentences but just adding a prepositional phrase is not at all likely.
