28.【犯罪率】

28.1 by 小舟90hou

貌似是GWD上的，关于一个地方的犯罪率，犯罪人数增加~~

（找到了，但好像不是这题……）

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 fort 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 fect 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 fective is being done about crime.

（后来我发现更加像这一道……GWD上关于crime rate的就这两道了。）

The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale.

The argument above is flawed because it fails to take into account

1. Changes in the population density of both Meadowbrook and Parkdale over the past four years.
2. How the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale
3. The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale
4. The violent crime rates in Meadowbrook and Parkdale four years ago
5. How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.

答案选D

原文结论的意思实际为：现在M和P哪个犯罪率高。

在得出这个结论时原文提出的证据是和四年前比的数据，即以四年前的犯罪率作为基础，所以要比较现在的犯罪率，必须比较四年前的犯罪率。如果四年前M的犯罪率比P低很多很低，那末虽然这四年M的犯罪率增长达，但现在的犯罪率也会比P低。原文没考虑这种可能性。即D

B的意思为在过去四年里，M和P的人口增长率相比情况。因为犯罪率本身已算进了人口增长，所以不必再考虑人口增长情况。B是无关项。

（也不知道狗主们说的是不是一个题……28.2和GWD的不一样耶……）

28.2 by papercut123

这里有两个犯罪类型的名词我不认识，但不影响做题。姑且喊它们为A、B。A是B的子集，B又是crime的子集。 文章先指出：某区域是A型犯罪的重灾区，并且说这些A会被报告给警方。 然后：记录显示，去年该地区A型犯罪占B的比例是10%。但是，去年的实际情况是，A型犯罪占B的比例是小于10%的。 Q：最能解释这个现象的是？ B、A型犯罪被报告给警方的比率，远高于B中其它犯罪类型被报告给警方的比率。 E、什么今年和去年数据比较，云云。 个人看法：选了B。 除了B，我只能想起来E，E无关得太露骨。。。

28.3 by hcch1988

GWD原题 GWD-TN-14 Q22

In each of the past five years, Barraland’s prison population has increased. Yet, according to official government statistics, for none of those years has there been either an increase in the number of criminal cases brought to trial, or an increase in the rate at which convictions have been obtained. Clearly, therore, the percentage of people convicted of crimes who are being given prison sentences is on the increase.

Which of the following, if true, most seriously weakens the argument?

1. In Barraland the range of punishments that can be imposed instead of a prison sentence is wide.
2. Over the last ten years, overcrowding in the prisons of Barraland has essentially been eliminated as a result of an ambitious program of prison construction.
3. Ten years ago, Barraland rormed its criminal justice system, imposing longer minimum sentences for those crimes for which a prison sentence had long been mandatory.
4. Barraland has been supervising convicts on parole more closely in recent years, with the result that parole violations have become significantly less frequent.
5. The number of people in Barraland who feel that crime is on the increase is significantly greater now than it was five years ago.

答案选：C
