The Willett Museum, with one truly great work in an otherwise mediocre

collection, can afford to remain open only by selling that work.  But with

that work gone, the museum’s attendance figures, and thus its revenue

from admission tickets, would plummet.  The museum’s operating deficit

would correspondingly grow and the proceeds from the sale would quickly

be used up.  Therefore, the sale of the Willett’s single great work would

only delay the museum’s inevitable closing. 

 Which of the following, if true, most seriously weakens the argument?

      A   The Willett Museum derives some of its revenues from monies paid

       by the organizers of special functions held at the museum. 

      B The authenticity of the Willett Museum’s single great work has never

       seriously been in doubt. 

     C  The Willett Museum encourages patrons to make a donation to the

       museum every time they buy admission tickets. 

     D  The Willett Museum received its single great work as a conditional

       gift and would need to obtain permission to sell it. 

     E  The largest economic drain on the Willett Museum is the cost of

       insuring its single great work. 

 答案 E
