我在ab之间犹豫不定，哪个nn给讲讲吧！谢谢啦！

首先那个is应该是are因为它是many satellites的定语，所以ab肯定错了。

可是在og225中，that的先行词是one of the contiguous forty-eight states 的中心词one啊？

225. Minnesota is the only one of the contiguous forty-eight states that still has a sizable wolf population. and where this predator remains the archenemy of cattle and sheep.

(A)  that still has a sizable wolf population, and where

(B)  that still has a sizable wolf population, where

(C)  that still has a sizable population of wolves, and where

(D)  where the population of wolves is still sizable;

(E)   where there is still a sizable population of wolves and where

In choices A and C, the construction that still has ..., and where modifies Minnesota with clauses that are not gram­matically parallel. In choice B, the omission of and illogically makes the where ... clause modify wolf population rather than Minnesota--that is, choice B says in effect that the wolf population is where the wolf remains the archenemy of cattle and sheep. Choice D is grammatically constructed, but it lacks a conjunction that establishes a logical relation between the clauses; since Minnesota as a grammatical subject is separated from the clause following the semicolon, the statement there need not even pertain to Minnesota. In E, the best choice, the parallel construction of where ... and where ... allows both clauses to modify Minnesota.

就是看了og才对这道题有疑问的，有没有nn给解答一下啊～～help～～～～～
