GWD21-14

When storing Renaissance oil paintings, museums conform to standards that call for careful contriol 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 ?

(A)     Renaissance paintings were created in conditions involving far greater fluctuations in temperatures and humidity than those permitted by current standards.

(D) None of the materials in Renaissance oil paintings other than the paint are vulnerable enough to relatively wide fluctuations in temperatures and humidity to cause damage to the paintings.

我知道
        D为何对了
        因为没有比颜料更容易受到湿度和温度影响
        所以
        题目说
        既然颜料不受到影响那么其它就更不会受到影响了

但是
        那请大大解释一下
        为何A错好么?

A 我是这样解读的
        

我个人浅见
        如果过去和现在相比
        过去的温度和湿度变动幅度比现在还大
        那么如果过去都不受影响
        那么现在的湿度和温度变化没有以前大
        不就更不需要采取妥善保存环境么?

晕~~~

THX!!! I see!
