Passage Summary: Data shows that when the museum doesn't have a special exhibit, fewer people show up, but those who do show up stay 45 minutes longer than visitors do during special exhibits.

Reasoning: No reasoning provided (Fact Set).

Analysis: We are looking for a paradox here: why would people spend more time in the museum when there is arguably 'less' to see? Since this is an 'EXCEPT' question, four choices will provide a plausible explanation for this discrepancy, and one will not. A good explanation might involve crowd sizes making it hard to move quickly or the type of visitor who attends during off-peak times. The incorrect answer will likely be a 'neutral' fact that applies to both scenarios or something that makes the discrepancy even more confusing.
