Q14:

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.

   Answer:C
                

我选C，答案却是D，为何！？

recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity  这是文章给出的STIMULUS,是CONCLUSION的PREMISE

D选项说的是除了PAINTING外(与PREMISE无冲突)其它油画材料不会因为fluctuations in temperature and humidity  对油画造成损害(对他因的否定,属于HIDDEN PREMISE).

所以是正确答案.

C选项其实是无关选项.文章一开始就说了是SORTING PAINTING, 与PAINTING无关的都是无关选项.
