请问一道新东方逻辑补充上的题section11-19th

Section 11

19th

19. It is widely assumed that a museum is helped finan-

cially when a generous patron donates a potential

exhibit. In truth, however, donated objects require

storage space, which is not free, and routine conser-

vation, which is rather expensive. Therefore, such gifts

exacerbate rather than lighten the demands made on

a museum's financial resources.

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

(A) To keep patrons well disposed, a museum will

find it advisable to put at least some donated

objects on exhibit rather than merely in storage.

(B) The people who are most likely to donate valu-

able objects to a museum are also the people

who are most likely to make cash gifts to it.

(C) A museum cannot save money by resorting to

cheap storage under less than adequate con-

ditions, because so doing would drive up the

cost of conservation.

(D) Patrons expect a museum to keep donated

objects in its possession rather than to raise

cash by selling them.

(E) Objects donated by a patron to a museum are

often of such importance that the museum

would be obliged to add them to its collec-

tion through purchase if necessary.

答案：E。请问E的意思是不是说，这些赠品是非常有价值的，如果不赠送的话有可能博物馆有必要去购买呢？这里面would be 是不是虚拟语气呢？请指教～

我对这道逻辑题的理解抱有犹豫，不是太确定我的理解是否正确，我怕理解错了，是蒙对的。如果E是这样理解的话，那就没疑问了。呵呵。。。

理解正确，加10分。
