Question ID:PT20 S4 Q9 Passage:Curator: The decision to restore the cloak of the central figure in Veronese's painting from its present red to the green found underneath is fully justified.  Reliable x-ray and chemical tests show that the red pigment was applied after the painting had been completed, and that the red paint was not mixed in Veronese's workshop.  Hence it appears likely that an artist other than Veronese tampered with Veronese's painting after its completion.Art critic: But in a copy of Veronese's painting made shortly after Veronese died, the cloak is red.  It is highly unlikely that a copyist would have made so major a change so soon after Veronese's death.

Correct Answer Choice:BChoice A:It is the main point toward which the argument as a whole is directed. Choice B:It is a subsidiary conclusion that supports the argument's main conclusion. Choice C:It is a clarification of a key term of the argument. Choice D:It is a particular instance of the general position to be defended. Choice E:It is a reiteration of the main point that is made for the sake of emphasis.
