请教OG12-22，谢谢各位！！

OG12-22. None of the attempts to specify the causes of crime explains why most of the people exposed to the alleged causes do not commit crimes and, conversely, why so many of those not so exposed "have".
(A) have
(B) has
(C) shall
(D) do
(E) could
答案是D
请问and, conversely, why so many of those not so exposed do，这句话的句子结构是什么？其中的so exposed do怎么理解呢？

与前面的那个why那个分句对应。

请问这两个分句的意思是什么呢？
why most of the people exposed to the alleged causes do not commit crimes
why so many of those not so exposed do

most of the people exposed to the alleged causes do not commit crimes 对应：
so many of those（people）not so exposed （to the alleged causes）do (commit crimes),两个句子平行，所以相同的部分就省略掉了。not so exposed do我的理解就是：（而那些）不那么暴露 （在所声明的原因前的人）会犯罪.
希望对你有帮助。
