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?

A. 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.

B. Former inmates are no more likely to commit crimes than are members of the general population.

C. 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.

D. Taking high school level courses in prison has less effect on an inmate's subsequent behavior than taking college-level courses does.

E. The governor's ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

先说说自己的理解:
论述认为接受教育有助于减少犯罪率.
问假设.
A和C都是双重否定句,考虑范围内.
根据取反削弱的原则,试试:
A. 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.
(取反1:Not being able ......likely 不学习也可能减少犯罪
 取反2:being able to .......unlikely 学习不可能减少犯罪)
明显削弱 偶选A
C. 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.
(取反1:were less likely 学习的人比不学习的人少犯罪.加强
取反2:were not likely 如上)
答案竟然是C
一头雾水!

这是一道GWD题，是assumption中的一道弥补排除它因题型，就是说如果 参加这个科的人本身素质高，即使不参加这个course，出狱后也不怎么doing criminal again，那么这个课程的效果就要被质疑，因此在上此课程之前，所有的criminals 的素质都一样+taking the course=提升了criminals的素质，降低了出狱犯罪的可能，才能说明是课程本身起到了作用，就像控制变量法一样，得把实验前，除实验变量以外的因素全部弄成一样的

谢谢楼上的解释,不过能否帮忙指出我采用取反削弱的方法解假设题和上面的分析当中有那些漏洞和缺陷呢?谢谢!
