A为什么不对啊？如果职工要求的工资高了，用于safty的钱也就少了。还是不能证明事故率会降低啊

问问题请先花一点时间排版, 这是基本礼貌

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.
=============================================================
argument提出一个因果:
When higher demand, more money is spent at the factory for safety precautions and machinery maintenance than when demand is low --> lower accident

反驳从因果下手
A) 薪资无关
B) 新员工未受训练, 意味即使安全花费高仍有可能比受训练的容易出意外, 另有他因
C) 离职时间无关
D) 非要说的话, 偏向支持
E) 非要说的话, 偏向支持
