15. The proposal to hire ten new police officers in LACE>MiddletownLACE> 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 LACE>United StatesLACE> cities, not all arrests result in convictions, and not all convictions result in prison terms.（E）

(E) LACE>MiddletownLACE>’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

题目是说funding的问题," but not the salaries of additional court

and prison employees " , 是说没有钱雇佣这些人, 增加警察有什么用呢？没

有讲和crime有什么关系．所以Ａ　是无关选项，

　Ｅ说警察数量已经＂reached a level ＂　可以deter犯罪，所以不需要雇佣

后面这些人
