Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within
narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the
kind of oil paint used in these paintings actually adjusts to climatic changes quite well.If, as some museum
directors believe, paint is the most sensitive substance in these works, then by relaxing the standards for
temperature and humidity control, museums can reduce energy costs without risking damage to these
paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate
that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to
withstand signifi cant variations in humidity.
In the argument above, the two portions in boldface play which of the following roles?
(A) The fi rst is an objection that has been raised against the position taken by the argument; the second is the
position taken by the argument.
(B) The fi rst is the position taken by the argument; the second is the position that the argument calls into
question.
(C) The fi rst is a judgment that has been offered in support of the position that the argument calls into
question; the second is a circumstance on which that judgment is, in part, based.
(D) The fi rst is a judgment that has been offered in support of the position that the argument calls into
question; the second is that position.
(E) The fi rst is a claim that the argument calls into question; the second is the position taken by the argument.

此题蓝字部分吧我搞晕了！sensitive我原以为是敏感的，即容易损坏的，而后面又说可以减低成本。这种自相矛盾的说法把我彻底搞晕，如果是考试状态，我将彻底崩溃！！
请教各位大侠们，解这道题的正确方法应该是怎样的？谢谢！！！！

Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within
narrow margins of temperature and humidity to inhibit any deterioration.
（1.背景信息，介绍文艺复兴时期的油画现在是怎么储存的）

Laboratory tests have shown that the
kind of oil paint used in these paintings actually adjusts to climatic changes quite well. （2.介绍新的发现：油画颜料其实很容易保存）

If, as some museum
directors believe, paint is the most sensitive substance in these works,
（3.提出下面的立场成立所需的假设：在组成这些画的元素里面，颜料是最敏感 也就说是 最容易坏的元素）

then by relaxing the standards for
temperature and humidity control, museums can reduce energy costs without risking damage to these
paintings.
（4.中间立场：由前面两条推出，博物馆不需要那么严格的温度和湿度控制，所以可以省钱）

Museums would be rash to relax those standards, however, since results of preliminary tests indicate
that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to
withstand signifi cant variations in humidity.
（5.最终的argument：尽管有了2中的发现，但由于石膏才是最容易坏的元素，导致3的assumption错误的，所以博物馆不应该草率地取消严格的温度和湿度控制）

这样思路应该比较清晰了。 楼主再看看选项D有没有道理吧

已经很久不在这个版混了 ~。~

还是回答一下吧。
------分割线----
BF1推BF2是对的。 请看一楼蓝色的第2点。 “实验结果表明，paint不容易坏”，然后再假设他是最sensitive的。

给个简单的analogy：比如说现在有研究结果表明。 手机屏幕其实砸不烂。 然后假设屏幕是手机上最容易摔坏的东西（BF1）， 那么我们就可以随便砸手机了（BF2）。 但实际上呢？这个假设是错的。 主板比屏幕更容易砸坏 。 所以还是不能随便砸手机（argument）。

就这么个逻辑。  挺绕的。 呵呵。 再想想。 应该就能明白了。

解释的实在是太棒了，一定要读懂题目，一开始就是这块弄不清原因！这么个例子一下子就明白了

明白了明白了，之前就是卡在第二点和第三点上

谢乳娃

解释的太好了，谢谢

一开始想不明白是因为不清楚paint和pesso的对比关系，还是伤在关键词上了
