The correct answer should be (E) because only (A) and (E) show parallelism. Option (A) is incorrect because of uses of WHICH that incorrectly refers to MOISTURE.
ReplyDeleteQUESTION:
My doubt here is that in the correct option is 'them' not referring to 'tourists'?
No. 'THEM' is not referring to tourist because it is neither the subject nor object of the sentence. This is one of the GMAT trap. In short, THEM correctly refers to subject of the sentence, i.e. CHAMBERS
RULE: If a noun is neither subject or object of main clause/sentence then it doesn't introduce pronoun ambiguity in that sentence.
