79. Whendemand for a factory’s products is high, more money is spent at the factory forsafety precautions and machinery maintenance than when demand is low. Thus theaverage number of on-the-job accidents per employee each month should be lowerduring periods when demand is high than when demand is low and less money isavailable for safety precautions and machinery maintenance.
Whichof 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. 但是原文最后提到了less money will be available，我做题的时候想的就是削弱这个结论，以至于选了D，请问为什么less money 跟fewer accidents per employee都在结论中提到了，却只是削弱后者而忽略前者呢？ 谢谢大牛们！
