没有讨论过的885-sec11-9

9.      The proposed urban development zones do not represent a new principle; it was employed in “Operation Bootstrap” in Puerto Rico.

(A) do not represent a new principle; it

(B) represent not a new principle, but one that

(C) are not a new principle; the same one

(D) are not a new principle, but one that（B）

(E) are not new in principle; it

这题为什么B可以而D不可以呢？

BTW： 本题在搜索功能中没有找到，谢谢！

实意动词不要随便替换，尤其是没有原因的情况下

zones are principle, 取非后的句子不觉得很怪吗? 既然zones和principle不失对等的概念, 似乎用represent更能表达逻辑意思吧.

但是我有个疑问, 可以用one指代复数名词吗?
