题目材料：
Stylistic evidence and laboratory evidence strongly support the claim that the magnificent painting Garden of Eden is a work of the Flemish master van Eyck. Nevertheless, the painting must have been the work of someone else, as anyone with a little historical and zoological knowledge can tell merely by looking at the painting.The animals in the painting are all vivid representations of actual animals, including armadillos. Yet armadillos are native only to Americas, and van Eyck died decades before Europeans reached the Americas.
In the argument given, the two highlighted portions play which of the following roles?
-
AThe first is a position that the argument seeks to reject, the second is evidence that the argument uses against that position.
-
BThe first and the second are each pieces of evidence that have been used to support the position that the argument opposes.
-
CThe first presents the main conclusion of the argument; the second provides evidence in support of that conclusion.
-
DThe first is a judgment that serves as the basis for the main conclusion of the argument; the second states that main conclusion.
-
EThe first is an intermediate conclusion drawn in order to support a further conclusion stated in the argument; the second provides evidence in support of that intermediate conclusion.
