Several years ago the diet industry introduced a variety of appetite suppressants, but some of these drugs caused (stomach disorders severe enough to have them) banned by the Food and Drug Administration.
(A) stomach disorders severe enough to have them
(B) stomach disorders that were severe enough so they were
(C) stomach disorders of such severity so as to be
(D) such severe stomach disorders that they were
(E) such severe stomach disorders as to be
D definitely sounds better than all the other choices, but the use of "them" does not convince me. To what does it refer: the drugs or the disorders? For this reason I choose E, notwithstanding its other imperfections.
(A) for me. 'Them' is a pronoun that refers to a plural antecendent. It clearly refers to the appetite suppressants. Diet industry (Industry here) is a singular noun and IMO, can't take 'them' as its antecedent.
I think "they" refering to "stomach disorder" does not make sense.
but some of these drugs caused such severe stomach disorders that they (stomach disorders) were banned by the Food and Drug Administration.
Clearly, No body will accept this. I think Pronoun reference problem appears when there is a CLEAR ambiguity in reference.
Correct me if I am wrong.
jpv, I do not know, I am confused with these pronoun agreements, if OA is D we will have to hope we don't get such questions on GMAT, if it is not I will have to stick to my convictions, let us wait & see.
I think in ETS way "D" is wrong...."that" introduces a restrictive clause and refers directly to "disorders", which "they" shud refer to as well. I think "E" is best of the lot. Altho I am not sure whether "such ...as ...to" is wrong usage in "E".
