Method of Reasoning. The correct answer choice is (B)
Due to the relatively complex structure of the curator's argument, it is important to understand it fully before proceeding to answer the question:
- Premise (1): Reliable tests show that the red pigment was applied after the painting had been completed
Premise (2): The red paint was not mixed in Veronese's workshop
Sub. Conclusion: An artist other than Veronese tampered with his painting after its completion
Main Conclusion: 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
As is often the case with Method of Reasoning/Argument Part questions, it is crucial to distinguish between the "subsidiary" conclusion and the "main" conclusion of the argument, particularly since the test makers will often try to trick you by prefacing the subsidiary conclusion with a typical conclusion indicator ("hence") while providing no conclusion indicators for the main conclusion. This tactic underscores the importance of understanding the function of each statement.
Compare the two contender conclusions and check to see which one answers the question "why?" — whichever one does, this will be the subsidiary conclusion of the argument. In this instance, the decision to restore the cloak is explained by the observation that someone must have tampered with the painting. Therefore, tampering with the painting is not the main conclusion of the argument, even though two separate premises are used in its support. By answering the question "why is the decision to restore the color of the cloak justified?", the statement that someone else must have tampered with Veronese's painting provides a premise for the main conclusion. Because this claim is both supported by the initial two premises and in turn supports another statement, it is a subsidiary conclusion of the argument. Answer choice (B) is therefore correct.
Answer choice (A) As discussed above, the main conclusion is the first sentence of the stimulus and not the last one, despite the misleading conclusion indicator ("hence") provided here. This answer choice is incorrect.
Answer choice (B): This the correct answer choice. See discussion above.
Answer choice (C) This statement does not clarify a key term. This answer choice is incorrect.
Answer choice (D) There is no general position in the curator's argument that needs defending. This answer choice is incorrect.
Answer choice (E) While the main point is in the first sentence, the last one does not reiterate it. Rather, it provides a rationale for it, by explaining why the decision to restore the color of the cloak is justified. This answer choice is incorrect.
