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

(E) says Analysis relying on X rays can only detect certain pigments underneath the painting.
Sorry....am still confused :(

Skeptics are saying X-ray examinations DO NOT show hidden mountains underneath the painting

E says that X-Ray machines can only detect CERTAIN PIGMENTS underneath the painting. So if the mountains are painted using some different pigment, X-Ray machines would not be able to detect it and hence it strengthens what the Skeptics are saying.
Heres how I understand it:

claimants: there are mountains behind mona lisa's painting

skeptics: there are no hidden moutains in the pic because it does not come up in the xray --> this would be weakened as you say in E because the xray only detects white colour...

hope that helps.

IMO: E

Clearly undermines and weakens.
Skeptic conclusion: No mountain detected
Skeptics premise: X rays

E undermines the skeptics premise.

Tip:The phrase "only" in Ans E limits the scope of X rays.

It seems to me that the right answer is E
