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.

Which of the following is a point at issue between Walter and Marissa

A.Whether a copy of an artwork could ever be visually indistinguishable from the original.

B.Whether the reproduction of a work of art is ever worth more than the original is worth.

C.Whether a copy of a work of art is ever mistaken for the original.

D.Whether a copy of a work of art could have all the same qualities as the original.

E.(E) whether originality is the only valuable attribute that a work of art can possess.
