19、E是说，捐献的东东对MUSEUM很重要，MUSEUM可能不得不要花钱买，这样就削弱了结论，因为这样日常维护的费用不仅无法省，可能还要花买的钱。

20、这题好象挺怪异的。B是说了一个hiden- premise。因为文章的前提premise是OIL价格很低，而结论是GAS也将低。而B是在利用文章中的premise，建立了一个假设，即GAS的用户很容易转移到OIL上。也就是说，如果GAS的价格一升高，用户就可能用OIL了，因为premise是OIL价格低，所以GAS的价格根本就升不高。

6、B说医药科学已经制造了很多治疗严重疾病的药了，无关！C说从试管里获得结果根本不可能，成了加强G的结论，同问题反了。E说，一些实验其实可以在CHICKEN EGGS里做了，不用在活体上做了。这样构成了加强。其实，如果抬杠的话，可以说E也有问题，因为文章并没有交代CHICKEN EGGS就没有痛苦，对吧。人家也是生命呀！

以下是引用wikeypig在2003-9-14 17:20:00的发言：
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.

答案是E。不懂！

此题逻辑错误在于偷换概念：

讨论的是那些donates a potential exhibit.
而作者却将其引申到所有的捐赠。
此时只需将论点再引回到原有概念即可。所以，答案是E

Hope that is helpful.

我仔细想了一下你说的：
此时只需将论点再引回到原有概念即可。所以，答案是E
有点不明白E怎么引回原有概念了呢？
是不是说，在展示时是捐赠，但要是长期时就要买下呢？

你可能是在理解问题是出了一点问题。捐赠人捐赠了后就不再收回来了。不是仅仅是为了展览，展览完后在收回。
e:回归原概念时说：捐赠人捐的通常都是值钱的且是具有展览价值的。
希望能够解释清楚。偷换概念是一种典型的逻辑错误。

wikeypig

E的意思是不是说如果不捐，博物馆也会买--》展品重要。
同时由于偷换概念的问题，根本不用考虑长期问题，只考虑捐品在展示时的重要性即可。

Bingo!
