QUESTION TYPE: Paradox
PARADOX: Job safety training led to an increase in the number of accidents.
ANALYSIS: Always, always pay attention to whether a question is talking about a number (e.g., 1,000) or a rate (e.g., 10%).
A safer work environment (the expert’s predicted result) will lead to a lower accident rate. But the number of accidents could go up or down, depending on whether the workforce grew or shrank.
___________
- This info about a different sector is irrelevant, and it offers no explanation. It might have been relevant if it offered a reason, but it didn’t.
- CORRECT. If the workforce increased in size, this could explain the increase in the number of accidents, despite a lower rate of accidents due to safety training.
- This could explain why the training was implemented, but not why the number of accidents continued to increase after the training.
- This shows the numbers are meaningful, but it doesn’t help explain them.
- The job safety training represented an improvement from the baseline. It doesn’t matter what the baseline level of safety was; we would expect things to get safer after an improvement.
