Logic Breakdown
Passage Summary: Even though having a boss watch you might change how you drive, the company thinks the rankings will stay the same because everyone is being watched equally.
Conclusion: The drivers who perform best while being watched by a supervisor are likely the best drivers under normal, unobserved conditions.
Reasoning: Every driver's performance is affected by the supervisor's presence, so the relative rankings should remain the same.
Analysis: The argument relies on a 'Gap' regarding how the supervisor's presence affects different individuals. It assumes that the 'supervisor effect' is relatively uniform across all drivers. If the presence of a supervisor made a great driver panic and fail, but helped a mediocre driver focus and improve, the rankings would be totally unreliable. To bridge this gap, the argument *needs* to assume that the supervisor's presence doesn't disproportionately benefit or hinder certain drivers in a way that reshuffles the leaderboard.

Unlock Full Passage6.Which one of the following is an assumption on which the argument depends?
Correct Answer
D
The argument needs the assumption that the supervisor’s presence affects all drivers in roughly the same way and to the same extent so that supervised rankings mirror normal rankings. Negation test: if drivers are affected differently, supervised rankings may not match normal rankings, undermining the conclusion.
