大全-Ⅱ-11

马尔代夫

大全-Ⅱ-11.       The cities with the densest population have the highest ratio of police officers to citizens. Such cities also have the lowest rates of property crime without contact between perpetrator and victim. Thus maintaining a high ratio of police officers to citizens can serve as an effective deterrent to at least certain kinds of property crime.

Which of the following, if true, most seriously weakens the argument above?

(A) The quality of training that police receive varies from city to city.

(B) High population density itself makes it difficult to commit a property crime that involves no contact between perpetrator and victim.

(C) Many nonviolent crimes in large cities are drug-related.

(D) A majority of the perpetrators of property crimes in densely populated cities are not apprehended by the police.（B）

(E) Property crimes without contact between perpetrator and victim represent only a small proportion of overall crime.

答案是B，没问题。请问E为什么不对？

不明白,为吗不选D啊

文中是由政府官员多，财产犯罪率低=》政府官员多对一定种类的财产犯罪有抑制作用

D选项说大多数罪犯没抓获，对财产犯罪率的高低并无影响，故无削弱作用

noss

其实，b的原因很简单，题干是找一个可以消弱命题的，命题是警察多了对财产犯罪的减少有好处，只要找到一个可能会

减少财产犯罪但与警察无关的就可以了。

显然，B是因为高人口密度本身就减少了财产犯罪！
