The proposal to hire 10 new police officers in Middletown is quite foolish. There is wufficient funding to pay the salaries of the new offices, but not the salaties 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 seriously weaken the conclusion drawn above?
a, Studies have shown that an increase in a city's police force does not neccessarily 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 nes police offices' salaries is approved, support for other city services will have to be reduced during the next fiscal year.
d, In most US 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 deterrnt effect on crime.
答案是:E 我选了D,我觉得E中的ratio好像没什么用吧,为什么到了一定的level,crime就能得到抑制呢,题目中不是说,officers越多,crime就越多吗??
自己实在是想不明白,请各位大虾帮帮忙!!!谢谢!!!
菜鸟试试回答一下,
警察数量上升---->用于arrest和conviction的雇员上升
至于arrest是不是会引起conviction,我觉得是无关项,只要真的有arrest发生就符合它的逻辑了。
E选项中的ration=警察数量/市民数量,警察数量上升了,市民数量没变,ratio必然上升的,
只要ratio上升抑制了犯罪,arrest就不一定会上升了。
不太明白啊,为什么ratio上升了,就一定能抑制犯罪呢,题目不是说警察数量上升就会导致arrest上升吗?!
原文中的会影起arrest上升是一个作者没有论证的隐含条件
E就是攻击说这个隐含条件是不成立的
situation:他不愿增加police officer的人数以此来不增加court prison emplyees的人数 答案说他增加police以震慑罪犯,也就是增加了police的人数,减少了犯罪的人数,从而不会增加court prison的人数 这样就weaken了吧
I thought the subject again and again.
Answer E is right, I accepted.
But what's wrong with answer D?
I think that D is also weakeness.

OG11-120 IS OG10-170
"看上去D也可以,但实际上属于多余的不当推理。不是所有的arrest会造成convictions 和prison,那么到底会有多少呢,并不知道,可能会造成没有sufficient funding to pay the salaries of additional court and prison employees,也可能不会,这是无法判断的"
ratio增加,不是一定就肯定抑制犯罪,weaken的题只要说得一点符合原文条件,但结论却和原文结论不同就ok阿~
不要那么看重选项里面的前因后果,只要选项遵循了满足条件,weaken结论就ok
take it easy 老美的题不会费你很多脑力的~
