大全－9－15

The proposal to hire ten new police officers in Middletown is quite foolish. There is sufficient funding to pay the salaries of the new officers, but not the salaries of additional court and prison employees to process the increased caseload of arrests and convictions that new officers usually generate.

Which of the following, if true, will most seriously weaken the conclusion drawn above?

(A) Studies have shown that an increase in a city’s police force does not necessarily reduce crime.

(B) When one major city increased its police force by 19 percent last year, there were 40 percent more arrests and 13 percent more convictions.

(C) If funding for the new police officers’ salaries is approved, support for other city services will have to be reduced during the next fiscal year.

(D) In most United States cities, not all arrests result in convictions, and not all convictions result in prison terms.（E）

(E) Middletown’s ratio of police officers to citizens has reached a level at which an increase in the number of officers will have a deterrent effect on crime.

这个题目的文章推倒是，增加警察＝》案子数量增加＝》法庭和监狱的管理人员增加＋不足以支付增加带来的工资数额上涨＝》招人是foolish.所以我选的是D，但是答案给的是E，不明白，请NN给讲讲。我虽然觉得D有无关的可能，但是觉得D很针对文章的推理过程，所以还是prefer to D.

E不刚好是你的推理里“案子数量增加＝》法庭和监狱的管理人员增加“中的否定或部分否定吗？因为案子数量可能不会增加，所以，削弱结论。

而D总体上，对 案子数量增加＝》法庭和监狱的管理人员增加 没有确定性的影响，增加警察，既可能使案子数量增加，也可能减少或不变。
