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?

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.

E. The number of people in Barraland who feel that crime is on the increase is significantly greater now than it was five years ago.

答案是C。不太明白C是什么意思。如果十年前增加最小蹲监狱时间，这和近5年监狱人数增加是什么关系？谁能举个具体数字的例子。

不明白D,假释的人少了，不是就有更多的人留在监狱了么？为什么不对？

比如以前5个送进监狱的人有3个保释出去了，现在只有1个可以保释，不就

增加了监狱人数了？？

A项 我眼一花,想 惩罚方法很多,那么被判这些刑的犯人就更多些

后来看了答案觉得A是无关的了

我的思维出了什么问题呢?
