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?

 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.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?

1. The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.

2. Hotels built since 1930 can generally accommodate more guests than those built before 1930.

3. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.

4. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.

5. The average length of apprenticeship for carpenters has declined significantly since 1930.

答案为什么是d呢？　这个不是加强了吗？

顶，都过一年了，还没有nn解释啊，我也不理解这道题！

这两个题已经有很多讨论了

1.如果接受教育的罪犯本身就比其他罪犯不容易犯罪那么结论就weaken

2.好的房子都留下了，不好的老房子都倒了，这样的比较不是对等的比较，把老的最好的房子，和现在的房子的平均水平来比，得出的结论本身就是带有倾向性的
