这个GWD答案怎么理解？GWD8-27

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?

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.

C项的意思是不是反了？有上学的囚犯比其他的囚犯更可能犯罪？

A项的ANYONE是个坑

TheAssembly

题干的逻辑是：
由于那些被放出来的人里上过课的犯罪少 所以上课能减低犯罪率
看起来逻辑没什么问题，考虑一下样本的代表性。如果那些上课的本来就不会释放后再犯罪，那就不是上课导致的犯罪减少了。

A不知道为什么错，楼下解释

这么理解A的坑：A项里ANYBODY，将原文的“囚犯”的概念无限上纲，难道把无辜群众也抓进去上课，以减低犯罪吗？所以无关。

C项比较难读，改写一下not less likely=more likely，成为：
The group of inmates who chose to take college-level courses were already more likely than other inmates to commit crimes after beingreleased.
意思是“选择上课的囚犯比其他的囚犯更可能犯罪。”
这意思不是跟原文反了？？

不好意思少写一句，C项是参考答案

TheAssembly

注意问的是ASSUMPTION。判断ASSUMPTION的方法按照OG来说就是取非验证。
NOT LESS 换成MORE其实是不太好的。
注意有的时候假设也是一种加强。如果硬是按照你的理解的话，C就加强了原来的论证，不是么
按你的翻译，选择上课的囚犯“本身（注意这个“本身”）”比其他的更容易犯罪，用个例子说明：
假设杀人犯都选择上课，偷盗犯不上，上过课后杀人犯比偷盗犯更不倾向犯罪，那不是说明“上课”取得了良好效果么？

仔细读选项，你忽视了ALREADY这个词

要证明的是这句话。你看两个样本比较，首先前提得正确无差异。C里面取非说，那些选择上课的人本身就是那种不太可能重新犯罪的人，这不是就说明了样本本身有差异性？所以错了。而C排除了这种可能。A跟这道题背道而驰啊！
