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.
又错一遍。原文说因为油漆放松标准后不会损坏,所以油画放松标准也不会损坏。
B 取反后-以现有标准,文艺复兴油画会损坏。要区分假设题和削弱题的范围。
D 正确 取反后-油画中除了油漆还有其他材料容易损坏
