谢谢你的解释。 我当时看了答案都没有想明白是为什么。 FEIFEI。。。。。。真让人伤心。
A is wrong because argument deduces the conclusion based on 2 data inputs. Majority is not a "value" judgement since it is more of a percentage, over 50%. B is wrong the argument never talked about "average member" C is correct, if the total poluation contains for example 99% non-cocaine user and only 1% of user, the majority of those tested positive could be people who never used cocaine. This, C contradicts argument,s conclusion. -- by 会员 apostlep43 (2007/11/15 14:33:00)
