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?
Studies have shown that an increase in a city's police force does not necessarily reduce crime.
When one major city increased its police force by 19 percent last year, there were 40 percent more arrests and 13 percent more convictions.
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.
In most United States cities, not all arrests result in convictions, and not all convictions result in prison terms.
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.
E. 正确。说明就算真的增加警察了,不但不会导致逮捕和定罪的数量增加,反而能降低逮捕和定罪数量。D. 无关。“并非所有”即是说“有些还是”,“有些”这类指代范围过于抽象的词,没有代表性。
而且D还错在用总体推个体,
总体是:大多数美国城市,不是所有的逮捕最后会被定罪,不是所有被定罪的最后会进监狱
个体是:在Middletown这个地方的情况,而这个Middletown可能就是那些少数的美国城市之一。
