53、current legislation that requires designated sections for smokers and nonsmokers on the premises of privately owned businesses is an instrusion into the private sector that cannot be justified. the fact that studies indicate that nonsmokers might be harmed by inhaling the smoke from other's cigarettes is not the main issue. Rather, the main issue concerns the government's violation of the right of private businesses to determine their own polices and rules.
which one of the following is a principle that, if accepted, could enable the conclusion to be properly drawn?
A. government intrusion into the policies and rules of private businesses is justified only when individuals might be harmed.
C. the right of businesses to self-determination overrides whatever right or duty the government may have to protect the individual.
答案：C
为什么A选项是个削弱呢？

65、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 depend on the assumption that
E. the police cannot continue writing as many speeding tickets as ever while diverting resources to combating drugrelated crime.
答案就是E。但是我有一点想不明白：题中，写的罚单数量不变----〉人力被困在了打击与毒品有关的犯罪中的说法是不正确的。（结论）该命题的逆否命题是：人力资源被困---〉不能写那么多的罚单（就是E)。只能说不能写罚单是人力被困的必要条件，但是假设不应该是结论的必要条件吗！而结论是人力资源被困的说法是不正确的！我怎么越想越想不明白啊！！
