Q27:

Newspaper editorial:

In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  art 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.

答案是A, 为什么?

I prefer to C,which looks like a standard answer of GMAT

我同意A 题目的意思是政府的目标(犯罪率下降)不会实现.因为只有COURSE才可以DETER

A 取非就可以得到

C 取非后就是

The group of inmates who chose to take college-level courses were already less likely than other inmates to commit crimes after being released.(选课后也不会降低犯罪)

4楼说得好，C 取非后就是

The group of inmates who chose to take college-level courses were already less likely than other inmates to commit crimes after being released

但是，正因为这样，就削弱了原结论。选择上课的人已经有“觉悟”了，会少犯罪。满足assumption取非削弱。

同意C.

题中说到inmates释放后,那些上过college-level courses的人比其他的inmates犯罪要少得多.也就是说是因为上课,犯罪就少的.问assumption.

把C取非的意思是:那些选择去上课的inmates本来(already)已经比其他的inmates在释放后要不容易犯罪或者说犯罪的可能要小得多.就是说这些inmates本身释放后犯罪的可能性就小,并不是因为上课,犯罪就少的.weaken了结论说的是因为他们上了课才比其他的inmates要犯罪少的.
