### HideShow timer Statistics

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 Vinciâ€™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 skepticsâ€™ 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 Vinciâ€™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 Vinciâ€™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 paintingâ€™s surface layers.

I got the OA tru POE, but not quite convinced!

Which of the following, if true, would tend most to weaken the force of the skepticsâ€™ objections?

(A) There is no written or anecdotal record that Leonardo da Vinci ever painted over major areas of his Mona Lisa.--->out of scope.
(B) Painters of da Vinciâ€™s time commonly created images of mountainous scenery in the backgrounds of portraits like the Mona Lisa. ----> not related coz it doesn't mean that Da Vinci would have the same drawing style.
(C) No one knows for certain what parts of the Mona Lisa may have been painted by da Vinciâ€™s assistants rather than by da Vinci himself.---> out of scope
(D) Infrared photography of the Mona Lisa has revealed no trace of hidden mountainous scenery.-----> even strengthen the skeptics' argument
(E) Analysis relying on X-rays only has the capacity to detect lead-based white pigments in layers of paint beneath a paintingâ€™s surface layers. --> Yeah~!

E it is.

E it is.

It is the only one (minus D) which addresses the argument and discusses Xrays. D would strengthen the argument, so E it is.
