标题: OG10-188(lawyer版) 求援。 [打印本页] 作者: jessicaxier 时间: 2010-12-22 06:12 标题: OG10-188(lawyer版) 求援。 188.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) It s 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.
正确答案是B，我比较菜鸟，对题目比较困惑，没有太清楚的看出来是什么意思，以及比较明显的削弱的点应该在哪，求大家指导~~不胜感激。作者: sdcar2010 时间: 2010-12-22 07:14
This is a simple question in terms of logic.
Premise: 1) when demand is high, more money is spent for saftey precautions and machinery maintenance than when demand is low.
Conclusion: The average number of work-related accidents per employee per month should be lower when demand is high than when demand is low.
The assumption is that 1) NOTHING else changes or matters when comparing safety data between high demand period and low demand period; 2) more money spent on safety precaustions and machinery maintenance will lead to reduction on accident rate per worker.
To weaken this argument, you need to find a condition, if true, casts more doubt on the argument. One way to do this is to attack the assumptions. B simply does that by pointing out one key difference between the two periods - new workers are hired during the high demand period. These workers lack safety training and would be accident-prone during the high demand period. Thus, the argument is weakened.作者: jessicaxier 时间: 2010-12-22 17:55 标题: 多谢~ 大侠, 你解释的太清楚了, 多谢多谢~~~ 不胜感激~~~作者: 小怀 时间: 2011-2-18 09:57
请问，那less money is available for safety precautions and machinery maintenance是否也是conclusion的一部分？这部分对于题目起什么作用呢？作者: sdcar2010 时间: 2011-2-18 10:13
LS, it is a state associated with when demand is low.
