Walter: A copy of an artwork should be worth exactly what the original is worth if the two works are visually indistinguishable. After all, if the two works are visually indistinguishable, they have all the same qualities, and if they have all the same qualities, their prices should be equal.

Marissa: How little you understand art! Even if someone could make a perfect copy that is visually indistinguishable from the original, the copy would have a different history and hence not have all the same qualities as the original.

(B) Raising a point that would undermine one of the claims on which his conclusion is based

(C) Questioning his claim that a perfect copy of a work of art would be visually indistinguishable from the original

(D) Giving reason to believe that Walter is unable to judge the quality of a work of art because of his inadequate understanding of the history of art（B）

(E) Proposing alternative criteria for determining whether two works of art are visually indistinguishable

答案B。我选了D，觉得更切合题目啊，B也对的，但是不如D切合题目嘛。哪位牛牛来讲讲？

D纯粹是人身攻击嘛！

because of his inadequate understanding of the history of art文中也没有提到过。

W认为B因素决定的A，M认为A结论不仅由B因素决定的，还由C因素决定。

因此Raising a point undermine W的claims

明白了，谢谢。
