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 significant variations in humidity.

In the argument above, the two portions in boldface play which of the following roles?

A.      The first 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 first is the position taken by the argument; the second is the position that the argument calls into question.

C.      The first 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 first 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 first is a claim that the argument calls into question; the second is the position taken by the argument.

答案为D，最近开始做GWD，BF题必错，请问下NN有没有什么心得？

 D

这个题的conlusion 是  最后一句话

逻辑链是这样的

试验证明  用在painting中的oil paint是不容易被腐蚀的

黑体提出  paint是painting中最脆弱的东西,

两者结合起来,博物馆应该降低储存标准

最后一句话反驳了这个观点,说gesso才是painting中最脆弱的东西,而它对湿度是敏感的

要分清paint和painting

painting是一个整体,有画也有画框还有别的

paint只是指画,
