Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels build afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care and effort than carpenters who have worked on hotels built subsequently.

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

D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
E. The average length of apprenticeship for carpenters has declined significantly since 1930.

我选的是E；答案给的是D。
我选E的原因是 “有其他原因导致这种质量下降”，但是选D我着实不理解！

Hunter: Hunters alone are blamed for the decline in Greenrock National Forest's deer population over the past ten years. Yet clearly, black bears have also played an important role in this decline. In the past ten years, the forest's protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.

In the hunter's argument, the boldface portion plays which of the followng roles?

A. It is the main conclusion of the argument.

答案是A。我主要的疑问是：“and examination of black bears found dead in the forest during the deer
hunting season showed that a number of them had recently fed on deer.”最后这半句话，怎样理解？我怎么觉得是熊用来喂鹿了？？

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?

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.

正确答案是C。
我灰常不理解。。。。
