Kate: The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.Scott: The population of the spruce budworm, the warbler's favorite prey in North America, has been dropping. This is a more likely explanation of the warbler's decline.

Which of the following, if true, most seriously calls Scott's hypothesis into question?

[求助]GWD-3-32 AND 38

Q32:

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?

 

  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.   (i chose c)

Q38:

Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.

 

Scott:  The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler’s decline.

 

Which of the following, if true, most seriously calls Scott’s hypothesis into question?

 

  1. The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.
  2. The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.
  3. The drop in the population of the spruce budworm is expected to be only temporary.
  4. Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations.
  5. Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.(i chose c)

我是觉得c 没有什么说服力,但是A讲到了另外一种鸟,不是无关选项吗?

Q32.
Situation: Governor wants to get tough with the crime and make the prison conditions harder -> not allow inmates to take college level courses.

Argument: Inmates who had taken such courses committed far fewer crimes -> so governor's action is counter to his goal of reducing crime.  If not allowing inmates to take college courses is counter to governor's goal, then it means => not allowing inmates to take college courses does not reduce crime.  This is basically what answer A says.

Q38.
The question is not asking for conclusion nor what must be true, so the answer can have new elements that are not mentioned in the paragraph.

Scott says that the dropping of spruce worm,  not the climate change, is the cause of decline of songbirds.  To directly weaken his argument, we have to show that other birds, which live in and depend on the same climate but do not eat spruce worms, are also on the decline.  Answer A basically states that.
