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

正确答案为B，破解上这样说的：

(A) the human mind is not a "blank slate," but instead that结构不平行; developed as a way of solving表达复杂,直接改为developed to solve表达目的

(B) 正确, the human mind is not a "blank slate" but instead comprises…结构平行; 用developed to solve表达目的,简洁

(C) it造成两个主语，句子结构错误; instead of a "blank slate”意思表达不清。

(D) rather than it being a "blank slate,"结构表达复杂,且it多余应该删掉; developed as a way of solving表达复杂

(E) 整个句子结构表达笨拙,复杂，两个that从句之间缺少连词; developed as a way of solving表达复杂

但是B明显结构不平行啊，指教！！！

By recording the noise of crinkled wrappers as they were slowly stretched out in an otherwise silent chamber, and then digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not continuous but
                consisted of individual bursts or pops just thousandths of a second long.

(A) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not
                

(B) digitizing and analyzing the sound emissions on computers, a team of scientists found that the noise was not
                

(C) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not to be

(D) the sound emissions were digitized and analyzed on computers, a team of scientists found that the noise was not

(E) the sound emissions were digitized and analyzed on computers, a team of scientists found the noise not to be

正确答案为B，是不是系动词在but后面省略掉了？指教！！！

谢谢指点。

意思平行
the human mind is not a "blank slate" but instead comprises…结构平行
not 通常放在系动词之后
如果改为not 在is 之前是不是就很容易理解了 the human mind not
                is a "blank slate" but instead comprises…结构平行
