求助一道逻辑题

Curator: If our museum lends Venus to the Hart Institute for their show this spring, they will lend us their Rembrandt etchings for our print exhibition next fall. Having those etchings will increase attendance to the exhibition and hence increase revenue from our general admission fee.

Museum Administrator: But Venus is our biggest attraction. Moreover the Hart’s show will run for twice as long as our exhibition. So on balance the number of patrons may decrease.

The point of the administrator’s response to the curator is to question

(A) whether getting the Rembrandt etchings from the Hart Institute is likely to increase attendance at the print exhibition
(B) whether the Hart Institute’s Rembrandt etchings will be appreciated by those patrons of the curator’s museum for whom the museum’s biggest attraction is Venus
(C) whether the number of patrons attracted by the Hart Institute’s Rembrandt etchings will be larger than the number of patrons who do not come in the spring because Venus is on loan
(D) whether, if Venus is lent, the museum’s revenue from general admission fees during the print exhibition will exceed its revenue from general admission fees during the Hart Institute’s exhibition
(E) whether the Hart Institute or the curator’s museum will have the greater financial gain from the proposed exchange of artworks

质疑前提类

前提（因）：Having those etchings will increase attendance to the exhibition
结论（果）：Increase revenue from our general admission fee

Museum Administrator的response是on balance the number of patrons may decrease也就是那些因为Venus缺失而不来博物馆的人比因为有了Rembrandt etchings而来博物馆的人多，这个交换导致了实际参观人数减少了，而不是如前提中所说的增加了。Museum Administrator质疑了前提的准确性。
