这题狒狒和GWD答案有出入

Q27:

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?

1. 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.
2. Former inmates are no more likely to commit crimes than are members of the general population.
3. 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.
4. Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
5. The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

GWD里答案是A    狒狒里答案是C    应该是哪个呀..NN指点

我选C.取非削弱..

但是这道题还是挺晕的.也许今天做题有点多.

Why C？

取非似乎是支持结论。

C.

"The group of inmates who chose to take college-level courses were already less likely than other inmates to commit crimes after being released." ==> Little negative impact of the governor's action  ==> Original argument weakened.

???????????

inmates less likely  to commit crimes

和

governor's ultimate goal"reduce the crime rate"不是一致吗？

我觉得选A

C项否定了since后面的内容，是否定前提吧，狒狒说不能否定前提啊
