试题详情
文章：
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.
题目：
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?
选项:
A、Its employees ask for higher wages than they do at other times. Its management hires new workers but lacks the time to train them properly
B、Its employees are less likely to lose their jobs than they are at other times.
C、Its management sponsors a monthly safety award for each division in the factory.
D、Its old machinery is replaced with modern, automated models.
答案:
B
提问：
想请老师解释一下D选项，听了录音以后不是很明白为什么D是支持选项。原文的事件是：需求高的时候安全方面花钱多，所以需求高的时候(与花钱少的需求低时期相比)事故发生率低。D 管理层每月赞助给每个部门安全奖（我的思路：每个月都有安全奖——事故率低也可能因为有安全奖，是一个他因，所以是一个削弱选项）
