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 modern, automated models.
LZ，我是这么理解的：employee觉得自己不会被炒鱿鱼所以平时干活吊儿郎当的进而导致事故，这是您的想法，从给出的条件来看不能推出Employee因为不被炒鱿鱼不努力工作或努力工作。但B可以推出，新员工因没有take a good traing－－推出影响新员工的工作效率的。希望我的解释对您有帮助。一起加油！作者: shinboy 时间: 2011-12-29 06:44
我明白你的意思，但是OG对C的解释为：Increased job security could result in an increased number of workers, which might increase the
total number of accidents. However, the conclusion is about the number of accidents per employee, so this point is irrelevant.
后面那部分的解释没有问题，关键是前面那部分，既然OG能从‘Increased job security ’推出‘could result in an increased number of workers’为什么我不能从‘Increased job security ’推出workers could just fool around during the working hours, for they assume that they wouldn't loss their jobs呢？作者: shinboy 时间: 2011-12-30 21:35
