1.        GWD-25-Q30

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 positiontaken by the argument.

试验认为油画能适应气候, 如果,经理相信, 颜料在这个工作中是非常脆弱的物质, 然后放松标准可以降低成本.----------黄色部分不理解. 第一句黑体和上下文有什么逻辑联系啊. ? 谢谢!

 黑体上面说"paint是可以根具温度的变化调节的(就是对温度的变化要求不是很高的意思)" .

"颜料在这个工作中是非常脆弱的物质"就是想说只要调节温控能在paint(paint可以的话,其它的也可以了)的调节范围内就可以了(温控可以不用那么精确,只要在paint的调节范围内就可以)从而省电.

对比一下：

GWD-8-Q22:

When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins. Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.

Which of the following is an assumption on which the argument depends?

A. Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards.

B. Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all.

C. Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.

D. None of the materials in Renaissance oil paintings other than the paint are vulnerable enough to relatively wide fluctuations in temperature and humidity to cause damage to the paintings.

E. Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created.
