KarishmaB GMATNinja I really wanted to go with D because it seemed like the absolute correct answer, but I eventually did not go with it because if felt the D (and E) brought in new information, saying "SO severe". I have always learned that we cannot change the meaning of the original sentence.
My question for you guys is what do we do in situations exactly like in this question, when the correct answer (D) might be misleading because it brings in new information that was not stated in the sentence (no one said it was SO severe) yet it really looks and feels like the right answer?
The decline of the mountain yellow-legged frog in the high reaches of the Sierra Nevada has become severe enough for the United States Fish and Wildlife Service quite possibly to list it as an endangered species in the near future.
(A) severe enough for the United States Fish and Wildlife Service quite possibly to list it
(B) severe enough so that the United States Fish and Wildlife Service could well list them
(C) severe enough for it quite possibly to be listed by the United States Fish and Wildlife Service
(D) so severe that the United States Fish and Wildlife Service could well list it
(E) so severe that they could well be listed by the United States Fish and Wildlife Service
Thanks in advance!
