1.         GWD-18-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, therefore, 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?            

答案是C单感觉C不对  人数增加必定是有新人进来
        而不管判刑期加长没，比如监狱里有50人，即使每个人再加20年，监狱的人数还是不会增加，只要没人进来

 

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 reformed 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.

怎么没人啊！ 大家讨论讨论！

原文没有说，没人进来。每年 不断的有新 审判，不断的有人新获刑，怎么会没人进来呢？

原文是说 在每年 新发生的审判的案件数，获刑和获刑人数没有比 过去去年多，发生还是发生的，流量 不增长而已。

于是有人假设是因为 被判 坐牢的人的增多了。

C说的是另一个他因：不断的 有新人进来，每个人在监狱里呆的时间多了，自然一段时间内的人口总量是上升的。

相当于一个水池原理.
