标题: 两道逻辑题求助 [打印本页] 作者: awei1018 时间: 2003-8-3 16:16 标题: 两道逻辑题求助 1,researcher studying drug addicts found that,on average, they tend to manipulate other people a great deal more than nonaddicts do.The researcher conclude that people who frequently manipulate other people are likely to become addicts. Which of the following,if true, most seriously weaken the researcher's conclusion? 答案 After bccoming addicted to drugs,drug addicts learn to manipulate other people as a way of obtaining drugs. 这道题题干是说研究表明对毒品上瘾的人相对于不上瘾的人更倾向于控制别人.所以研究者得出结论:经常控制别人的人容易变成毒品上瘾者. 我觉得该答案是在解释题目中"对毒品上瘾的人相对于不上瘾的人更倾向于控制别人"的原因,而这里让我们削弱的是题目中的结论,我觉得这个选项和该结论没有什么关系啊? 还望知道的朋友指教一下!!
2,Advertisement:For sinus pain,three of four hospitals give their patients Novex So when you want the most effective painkiller for sinus pain,Novex is the one to choose. Which of the following,if true,most seriously undermines the advertisement's argument? 答案Unlike some competing brands of painkillers,Novex is available from pharmacies without a doctor's prescription. 题目中说因为有四分之三的医院给病人开novex,所以NOVEX最有效. 答案中说N药比起别的药来在药店有授而无须医生的处方,我觉得这个论据因该是支持为什么很多人N因为容易买到,但是和题目要削弱的有效与否没有什么必然的关系啊?所以我不懂这是一种什么削弱方法?? 望赐教!!作者: hexin 时间: 2003-8-3 16:33
1。这道题题干说：经常控制别人的人—〉变成毒品上瘾者。但是答案说了：实际上是毒品上瘾后—〉控制别人以获得毒品。是对原题因果关系的否定。削弱的是原题的推论。
