Using computer techniques, researchers analyze layers of paint that lie buried beneath the surface layers of old pantings. 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 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) 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.

答案 E

为什么B 不对呢？不是同样能削弱吗？ 难道属于无关选项？

修改过了，这样行吗？

文章说这画里的山是后来画上去的。反对者说，X检测不到这山。

结论就是WEAKEN反对者的话。找一个对X检测的怀疑就好了。

(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

X射线只不过看到点色块, 根本分不清楚山不山的。

B.别的画家关文章什么事情呢?就算其他所有的画家都不后来画东西上去，或者后来画东西上去，这画还是这画啊。诉诸与大众?
