71. More than a year ago, the city announced that police would crack down on illegally parked cars and that resources would be diverted from writing speeding tickets to ticketing illegally parked cars. But no crackdown has taken place. The police chief claims that resources have had to be diverted from writing speeding tickets to combating the city’s staggering drug problem. Yet the police are still writing as many speeding tickets as ever. Therefore, the excuse about resources being tied up in fighting drug-related crime simply is not true.

The conclusion in the passage depends on the assumption that

A.      every member of the police force is qualified to work on combating the city’s drug problem

B.      drug-related crime is not as serious a problem for the city as the police chief claims it is

C.      writing speeding tickets should be as important a priority for the city as combating drug-related crime

D.      the police could be cracking down on illegally parked cars and combating the drug problem without having to reduce writing speeding tickets

E.       the police cannot continue writing as many speeding tickets as ever while diverting resources to combating drug-related crime

参考答案：E 思路：结论是由于对超速行驶开出的罚单并未减少，所以资源并未转移，其逆否命题则是，资源如果真的转移，罚单一定减少，也就是E指出的 — 罚单不可能与原来一样多。

看了答案，不明白！，如果我们将E取非，我觉得是支持了结论。请各位牛牛指点！

思路是这样的，原来说是要将资源从处罚超速，转向乱停车，使其下降，而事实是没有发生。而主要官员的解释是，资源从speed ticket 下来转向了处罚drug problem。就是说没有转向乱停车。

而同时发现，超速罚单没有减少，说明转向drug problem只是个托词。

对E取非：the police can continue writing as many speeding tickets as ever

while diverting resources to combating drug-related crime

警察可以继续开一样多的超速罚单，同时又将资源转向combating drug-related crime 。那么这样的话，乱停车的下降应该可以发生的，但是事实是没有发生。

问题的基础就是，警察只能做一件事，不能又开超速罚单，又去管药物问题，再去管乱停车问题。

所以如果真的从超速罚单转到药物问题的话，应该事罚单减少。
