单选题 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、 (E) the police cannot continue writing as many speeding tickets as ever while diverting resources to combating drugrelated crime.

【正确答案】 E

【答案解析】[解析] 作者根据警察们写的超速罚款单的数量不变，而做出人力被困在打击与毒品有关的犯罪中的说法不正确的结论。该命题的逆否命题是：如果人力资源被困在了打击与毒品有关的犯罪中的说法是正确的，警察们将不能写那么多数量的超速罚款单。因此(E)是正确答案；选项(A)、(B)、(C)和(D)均不能从本题的论述中合理地推出。
