大全 test1 12题

请高人给解答下，E怎么就对了？

12.  Using computer techniques, researchers analyze layers of paint that lie buried beneath the surface layers of old paintings. They claim, for example, that additional mountainous scenery once appeared in Leonardo da Vinci’s Mona Lisa, which was later painted over. Skeptics reply to these claims, however, that X-ray examinations of the Mona Lisa do not show hidden mountains.

Which of the following, if true, would tend most to weaken the force of the skeptics’ objections?

(A) There is no written or anecdotal record that Leonardo da Vinci ever painted over major areas of his Mona Lisa.

(B) Painters of da Vinci’s time commonly created images of mountainous scenery in the backgrounds of portraits like the Mona Lisa.

(C) No one knows for certain what parts of the Mona Lisa may have been painted by da Vinci’s assistants rather than by da Vinci himself.

(D) Infrared photography of the Mona Lisa has revealed no trace of hidden mountainous scenery.（E）

(E) Analysis relying on X-rays only has the capacity to detect lead-based white pigments in layers of paint beneath a painting’s surface layers.

题目的意思：通过计算机技术， researchers 分析出了一些古画是一层颜料覆盖着另一层的，researchers就举了蒙娜莉莎为例，说蒙娜莉莎把山盖住了。但是skeptics(反对者)说通过X光的检查，没有发现蒙娜莉莎把山盖住了。所以他们说的不会。

要weaken skeptics 的观点

只有E可以，E说X光检查的局限性，它只能查出用lead-based white pigments 画的画有没有覆盖第二层颜料。其他种类的X光看不出来。

A选项犯的是没发现就是不存在的错误。

B无关选项 C不知道蒙娜莉莎是不是达芬奇画的还是他助理画的也是无关选项

D文中没提到Infrared photography 红外线摄像 ，也是无关选项
