A study conducted over a 6-month period analyzed daily attendance and average length of visit at the local art museum. The results showed that when the museum was not featuring a special exhibition, attendance tended to be lower but patrons spent an average of 45 minutes longer in the museum than when it was featuring a special exhibition. Each of the following, if true, could help to explain the differing average lengths of visits to the museum EXCEPT: ['Visitors to the museum during special exhibitions tend to have narrower artistic interests, and do not view as many different exhibits during their visit.', 'A plan to extend normal museum hours during special exhibitions was considered but not enacted during the period studied.', 'Admission tickets to the special exhibitions at the museum are issued for a specific 1-hour period on a specific day.', 'Many people who go to special exhibitions are on organized tours and do not have the opportunity to browse.']
