Questions 8—9
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.

Marissa uses which of the following techniques in attempting to refute Waiter’s argument

A．Attacking his assumption that the price of an artwork indicates its worth.

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.

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