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?

1. Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards.
2. Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all.
3. Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.
4. 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.
5. Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created.

答案是D,我选的是B,那里有什么material了？B为什么不对呢？谢谢！

Why u selected B?  B seems irrelavent as the question only talks about whether museum should use protection standard or not.  Has nothing to do what will happen under current standard.

B说现在的条件下，油画不变质，但不能说明结论改变条件是否可行.

D is right.

Look at the bold-faced worlds:  "recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity."

Now, try to read D one more time. Can you feel the pulse here?

现在明白D了，我当时只是想着现在条件都够了，就不用采取什么措施了，所以museums could relax their standards and save money without endangering their Renaissance oil paintings。但是我的思维错哪了。谁给我讲讲吧，愚笨在下。
