79. 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 ddtrue 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.


一开始说，more money is spent at the factory. 所以，xxxxxxx，less money is avaliable for xxxxx。

题目的逻辑就没有看懂，为什么前后矛盾？

When demand is high, more money is spent on safety precautions and machinery maintenance.  (let's say 10K)
When demand is low, less money is spent on safety precautions and machinery maintenance.  (let's say 5K)

Common sense is more money spent,  less accidents. Therefore, fewer accidents when demand is high; more accidents when demand is low.

This is the reasoning. (And it is true if all others stay the same)

It can be weakened because of a difference in other factors: Its management hires new workers but lacks the time to train them properly.

You can still have more accidents when demand is high despite your high spending on safety, because there are more poorly trained during the busier seasons.
