Passage Summary: Because vacations help reduce stress, a manager thinks that breaking your time off into many small trips is the best way to stay refreshed.

Conclusion: To minimize work-related exhaustion, employees should take several short vacations throughout the year instead of one or two long ones.

Reasoning: Every vacation taken by an office worker leads to a significant reduction in psychological exhaustion.

Analysis: The manager's logic is a bit like saying that because every glass of water hydrates you, ten tiny sips are better than one full glass. The flaw lies in the assumption that the frequency of vacations is the only factor that matters, ignoring the potential benefits of the duration of a single long break. Look for an answer that highlights this failure to compare the cumulative effect of many short breaks versus fewer long ones.
