一道看不懂的逻辑 ！

lllmmm

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?

A.    In Barraland the range of punishments that can be imposed instead of a prison sentence is wide.
B.    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.
C.    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.
D.    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.
神马东西啊 ？

应该是说这么多年来从来都没有发生过如此之多的增加~~巴拉巴拉~（剩下的句子很容易懂了吧~）
就是说监狱人多是因为犯罪的增加，从下列哪个选择中可以削弱这种观点。
我觉着选A.因为这个选项说的是虽然人犯罪的很多，但大多数可以被处罚而不是被判入狱。
B的话呢说解决了问题是不对的。
C选我也没太看懂，估计是说对那些长时间入狱的人的一些神马政策。
D是说假释的和题目没啥关系、
E 是说群众认为犯罪率提高了。

If the prison terms are longer than before, the prisoners have to stay longer in the prison and cause increase in prison population even though the same number of prisoners are in the prison.

兄弟一点拨如梦初醒~~不过能不能解释下A为什么错了啊~

sdcar2010

wide means could be short, could be long.

mahaofei001

wide 看上去是说range的吧~

第一感觉选C
A说用其他punishment代替入狱，但是这个也不能削弱监狱的人增加的事实。

C就是说明是其他原因导致监狱的人增加。

When the range is wide, it could mean the prison term is either very short or very long.  Thus, it is not SUFFICIENT to lead to the conclusion that the average prison term for inmates are LONGER. This is very similar to the GMAT Math DS type of question, if you can get it.

原文说的“审判比率没有提高”和“人数增加”推出“被判入狱的比率提高”。隐含的假设就是所有入狱罪犯的判刑年限是相似的。
A说，有其他方式来代替入狱。但如果被判入狱比率因此低于往年，人数应该减少（因为过去被判入狱的人被释放）。
C说，10年前一个改革，提高了以前就被关在这里的人的最短服刑年限。这意味着以前入狱的人的服刑年限比现在的要长，换句话说，出狱的人减少，入狱的人数不变的情况下，人数也会增加。
