以下两道题出自XDF补充练习里的section11的最后两题，谁能帮忙分析一下，有点想不通。
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.
20. Despite the approach of winter, oil prices to indus-
trial customers are exceptionally low this year and
likely to remain so. Therefore, unless the winter is
especially severe, the price of natural gas to indus-
trial customers is also likely to remain low.
Which of the following, if true, provides the most
support for the conclusion above?
(A) Long-term weather forecasts predict a mild winter.
(B) The industrial users who consume most natural
gas can quickly and cheaply switch to using
oil instead.
(C) The largest sources of supply for both oil and
natural gas are in subtropical regions unlikely
to be affected by winter weather.
(D) The fuel requirements of industrial users of nat-
ural gas are not seriously affected by the
weather.
(E) Oil distribution is more likely to be affected by
severe winter weather than is the distribution
of natural gas.

19、相反论据削弱型，答案（E）
题干：博物馆接受的捐赠反倒成为经济负担，储藏空间，保管哪来的钱呀！
削弱：怎么会呢，这些东西都挺重要的，没人捐赠博物馆也得自己去买。（别占了便宜还不知足）
20、它因配合型加强，答案（B）
题干：油价挺低的，照此下去，天然气的价格也高不了。
加强：老用天然气的人，都能转成用油，反正不费事儿。（所以天然气贵不了，一贵了不就没人用了吗）
个人意见！
