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.


这个选B，可是E为什么不对呢~

莫非lz认为先进的自动化机器会导致更大更频繁的事故不成？

E是个support而不是weaken(serious doubt)，即如果是这样子更换了机器，那么demand is high的时候事故应大幅减少，从而支持了文中的conclusion。
