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 from 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.

考题讲解

情景：为了减少犯罪率，议员决定把监狱的环境弄的艰苦一些。一种艰苦的方式就是取消监狱中大学等级的课程。然而，这个行为却违背了初衷，因为凡是上过大学等级课程的人出去之后犯罪率都比较低。

推理：

前提：“上过大学等级课程”和“不容易犯罪”之间存在正相关关系
结论：为了减少犯罪率，不应该取消监狱中大学等级的课程

答案预估：

要么同时提及“上过大学等级课程”和“不容易犯罪”，要么给“不容易犯罪”另外一个原因。

选项分析：

A选项：在监狱服刑期间没有能力去参加大学等级课程的学习不会阻止任何人去做那些从前他不敢做的犯罪行为。选项A取非之后是“没有能力上课有可能会阻止那些本来可能犯的罪”。但这个选项没有说出会不会能减少那些本来不会犯的罪。因为结论指的是一切犯罪嘛，选项A只说了会减少那些本来会犯的罪，所以其实不能质疑到结论。譬如，本来这帮人只会犯偷窃罪，没能力上课确实会让他们不敢偷了，但，因为没上课没有生活常识，就开始去“打砸抢烧”了。这样算下来，还是可能让犯罪更多而不是更少了。因此，取非后不能削弱。

B选项：有前科的人不会比一般的民众更容易犯罪。本选项勉强算是提到了“果”中犯罪率低的问题，但是没能解释为什么会有犯罪率低这个现象，也没有提到“因”中大学等级课程的问题，所以不是答案。

C选项： Correct. 选择上大学等级课程的罪犯不是本身就已经更加不可能在出狱后犯罪。本选项给出了一个原因来解释“犯罪率低”，即，是罪犯本身的特性导致的犯罪率低。

D选项：上高中等级的课程对于在监狱中罪犯的影响不如上大学等级课程的影响。该选项只谈到了“因”的部分，没有提及“果”。

E选项： 政府最终的目的是通过说服人们相信对于犯罪已经做了些有效的事情来增加名气。本选项没有提到因和果的任何内容，不能成为答案。
