标题: 菜鸟求助~OG12 81 [打印本页] 作者: hehe316 时间: 2011-8-29 21:28 标题: 菜鸟求助~OG12 81 When demand for a factory's products is high, more money is spent at the factory for safety precautions and machinery maintenance than when demand is low. Thus the average number of on-the-job accidents per employee each month should be lower during periods when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance.
Which of the following, if true about a factory when demand for its products is high,casts the most serious doubt on the conclusion drawn above?
A) Its employees ask for higher wages than they do at other times. B) Its management hires new workers but lacks the time to train them properly. C) its employees are less likely to lose their jobs than they are at other times D) Its management sponsors a monthly safety award for each division in the factory. E) Its old machinery is replaced with moderns, automated models. 我选的是E，因为我看到好多总结都说，在做WEAKEN的题型中，对conclusion提供另外一种解释的选项可以是对的。那么E中，我的理解是在高需求下之所以事故少不是因为那些更多的钱花费在维修养护，而是因为新机器代替了旧机器，完全可以对结论提供另外一种解释啊，为什么不对啊？我是菜鸟，刚开始学，求拯救！作者: hehe316 时间: 2011-8-29 22:13

原题是问对结论的削弱，E项modern代替旧机器，新机器的事故一般都比旧机器事故要少，所以是对原题结论的加强。作者: hehe316 时间: 2011-8-29 23:18
不好意思 我比较愚钝 这不可以看成是他因型吗 又找了一个原因来解释结论。。。作者: hehe316 时间: 2011-8-30 17:23

兄弟，恕我直言，做逻辑题最忌讳这种自己主观加想法的。谁告诉你钱花在买机器上啦？题目没说吧，没说就当不知道。不然逻辑题就没得做了。
