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?
Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards.
Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all.
Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.
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.
Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created.
oil paint is a thick paint used by artists, usually in plural forms.
assumption=negate choices=>to weaken: another factor can lead to a damage to R oil paintings as a result of lifting strict protection standards
D.R油画中除了颜料，没有其他材料会因为温度或湿度易被破坏。（画中除了颜料可能还有纸啊什么乱七八糟的不会对温度和湿度敏感）
B 原文只说明放宽条件后和现有条件效果一样，没说现有标准一定不会损坏
C 原文结论是油画不会被损坏 和其他展品无关
D 是答案。
