标题: [求助]求教一道CR题!

Newspaper editorial:

In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher. Part of this effort has been to deny inmates the access they formerly had to college-level courses. However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.

Which of the following is an assumption on which the argument depends?

Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
Former inmates are no more likely to commit crimes than are members of the general population.
The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

我选A,可答案说是C,搞不懂!请大家帮忙!

原文问 assumption, 而C采取了 not+weaken的形式

原文的论证关系是：因为 take college-level courses in the prison 和 inmates who had taken such courses committed far fewer crimes overall than other inmates 同时发生，所以前者是后者的原因。

而C选项的取非认为，以上两者同时发生，是因为后者是前者的原因，恰好削弱了原文的结论，

因此，C选项是一种not +weaken的assumption形式
