请教 OG-170

170. 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) 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.

可以理解答案选E, 但是D为什么不对呢？

既然not all arrests result in convictions, and not all convictions result in prison.可不可以说police officer的增加不一定导致additional court and prison employees呢？

记得前人说CR只由一个正确答案，请问D是什么类型的错误？

明白了！非常感谢斑竹！

就是帮助NEW POLICE OFFICERS进行之后的一系列工作的SUPPORT STAFFS。

这里是说有钱PAY NEW POLICE  OFFICERS 而无钱PAY 那些相关的SUPPORT STAFFS。
