OG-170

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.

答案是E, 但我选了A,还是不明白为什么A错

我赞成选E。但不明白ETS为什么解释D是irerelevant？我觉得D和论题还是相关的，因为它暗示不是所有警察逮到的犯罪行为都会被指控或者判刑，因此所需配套的法庭和监狱管理人员不是像想象中那么多。这也算削弱吧？只是比不上E那么强烈的否定而已。

可能我有点钻牛角尖了

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

我選了D

我也选了D，但确实E更加hit the point.

OG关于D的解释很理性，"not all"本来就是各比较含糊的概念，OG用rates来表示。因为文章或选项根本没有提及具体数字，则无法以此来得出任何结论，所以是无关的。

同意楼上snowjing，另外，我是这么理解：原文暗含的意思是说增加的警察必然会查出更多的犯罪情况，而只要查出来，不管将来结果怎样，都要经历一个审讯、部分收监的过程，这就需要增加更多的相关人员来干活，经费就必然会增加的。

D说的是一种普遍现象，这种现象不影响原文的推理，所以无关。

有谁能翻译一下E的意思？？？deterrent是什么意思？
