161. A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would tail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.
(A) would fail if the density of the timber wolf population in that region is more numerous than
(B) would fail provided the density of the timber wolf population in that region is more than
(C) should fail if the timber wolf density in that region was greater than
(D) will fail if the density of the timber wolf population in that region is greater than
(E) will fail if the timber wolf density in that region were more numerous than
D, the best choice, uses a correct sequence of present and future indicative verb forms--predicts, will fail, and is--in the three related clauses. Density, an abstract "mass" noun, is logically construed with greater than. In A and B, would fail disagrees with the other verbs in tense and mood. Choice A misconstrues density with more numerous than, and B uses the pretentious and illogical word provided for ifm a conditional clause after a negative idea (would fail). C's should fail and was are confusing and inconsistent with predicts. C and E use the absurd phrase timber wolf density. (The wolves are not dense; their population is dense.) E also uses an inconsistent subjunctive form, were, and misconstrues density with more numerous than.
1.是不是可数名词就可用more than
2.gmat 中是不是不用provided 来代替if

provided that 中的that是不能省略的
另外，我感觉GMAT语法中，在大多数情况下，would是被当成will的过去式，并不表示特别的含义。

much many得比较级都是more。所以棵树/不可书都可以用more than。本题不用more than是density的缘故。
