PREP 73~ 29号就考了~

Evolutionary psychology holds that the human mind is not a "blank slate," but instead that it comprises specialized mental mechanisms that were developed as a way of solving specific problems human ancestors faced millions of years ago.

(A) the human mind is not a "blank slate," but instead that it comprises specialized mental mechanisms that were developed as a way of solving

(B) the human mind is not a "blank slate" but instead comprises specialized mental mechanisms that were developed to solve

(C) the human mind, instead of a "blank slate," it comprises specialized mental mechanisms that have been developed to solve

(D) rather than it being a "blank slate," the human mind comprises specialized mental mechanisms that have been developed as a way of solving

(E) rather than the human mind's being a "blank slate," that it comprises specialized mental mechanisms that were developed as a way of solving

答案是B，可是我怎么就看不明白呢，B怎么平行呢？a blank slate是名词，但是comprise是动词啊？

但be 动词是在Not之前的呀，这样也平行马，不好意思，不太懂啊

我貌似是在以前的帖子上看见过NN说 is not…but (is)…但总感觉怪怪的~THX~

 我刚复习两天呢，但是看到你29号就要考试了，给你加油打气！！
