When demand for a factory's products is high, more money is spent at the factory for safety precautions and machinery maintenance than demand is low. Thus the average number of on-the-job accidents per employee each month should be bower 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 product is high casts the most serious doubt on the conclusion drawn above?

Correct Answer: Its management hires new workers but lacks the time to train them properly.
Work through the Answers, moving from Wrong to Right. Let’s take a look : (a) This has no impact on safety Eliminate. (b) This could definitely be bad for safety! If we have high demand and spend more on safety, but then tire new workers and don’t properly train then this could provide factor that leads to more accidents. Leave it in, try to eliminate other choices. (c) This has no impact on safety Eliminate. (d) This is probably relevant, but makes the factory more safe. It actually strengthens Eliminate. (e) Same probably as (d).If it is relevant at all, it strengthens Eliminate. So, indeed, we’re left with (b). The above process of finding answer is called process of elimination.
