GWD的一道逻辑 求助

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. 抓住结论！

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

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.（对not at all 取非是some）current standards导致some paintings受损，所以应加强current standards。 不能推出 could relax their standards.

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.

这个题我觉得BCD都行啊，对题目的一些解释看不明白  求详解~~

自己顶一下~

这个题是根据oil paint 推出 Renaissance oil paintings，所以假设的的话，应该建立这两者之间的关系。

C选项明显和结论无关，结论说 Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings. 结论只关心是否会损坏文艺复兴时候的油画，是否损坏其他画结论根本不关心。
B选项无关，argument讨论的是一个动态的过程，即改变标准是不是会变得更差，注意这个更字，至于当前什么状态不是很care，即使B选项为假，油画已经有一点点受损，但题干已经说了and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity，也就是说即使标准在变差也油画也不会比当前受损更严重。即也可以放宽环境标准。

应该只和Renaissance oil painting有关吧，所以C无关，B的话，现在的standard不造成painting的损坏，也不能成为可以relax的假设啊...只有D符合....这道题好像还有一道BOLD FACE的题，楼主看看那道题就可以找到答案了.....

assumption 题，三点最重要。第一：无关词排除法。第二：去非，削弱原文结论。第三：补原文前提和结论的缺陷。
Firstly，结论是：放松保存的标准，可以节约成本而且不会破坏文艺复兴的油画。
A：无关选项，出现了对比
B：错误选项，在现在严格的标准下，油画保存得很好。取非：在现在严格的条件下，油画不一定保存的好。。没有削弱结论说的放松标准可以保存油画。
C：无关选项，说道别的items
D:正确。除了油漆以外的其他材料比如画板材料，不受适度温度的影响。这符合了support 题中的一种方法，就是排除它因法。同时弥补了前提到结论中间的缺陷，光是oil paint 油漆不受影响，其他的因素如材料也不会受环境影响，作为前提假设。
E：五官选项。
