搞了半天没明白，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?



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.

答案是C，我理解题目是现在判的案子没有增加并且判刑的比率也没增加，所以监狱拥挤是因为正在服刑的人服刑期增加，但是C选项中十年前的司法系统对最低服刑期的增加为什么是削弱了题目呢？还是我理解错误了，请大家帮忙啊！～～～没几天就考了

十年前司法系统改革，延长了最低服刑期间，假设本该5年就出来的人现在要10年才出来，所以在后5年内，（极端情况）光进不出，导致人满为患，而不是因为犯罪人数增加了。
