Must Be True-SN. The correct answer choice is (D).
The stimulus can be diagrammed as follows (each statement is followed by its contrapositive):
- GA → AEEDeep AEEDeep → GA
- CE → AEE AEE → CE
The first arrangement could be stated as, “if a work of art is great, then it is a work of art expressing deep emotion.” The second arrangement could be stated as, “if the creator of a work of art is not capable of a certain emotion, then the work of art cannot express that emotion.”
Combining the first statement with the contrapositive of the second to arrive at:
- GA → CEDeep CEDeep → GA
If we are looking at a piece of great art, then, we can be certain that its creator has the ability to experience deep emotion. The contrapositive: an artist who cannot experience deep emotion cannot create great art.
The question that follows is a Must Be True question. The correct answer is the one that has to be true on the basis of the stimulus.
Answer choice (A): We cannot rule out such a possibility because the stimulus is concerned with the prerequisites of great art, while this answer choice discusses art more generally.
Answer choice (B): We can discard this choice based on the fact that the stimulus never used superlatives or dealt with matters of degree. The stimulus is concerned with thresholds – is a piece of art great or not? – since this choice cannot be confirmed by the stimulus, it cannot be the right answer to this Must Be True question.
Answer choice (C): This is not the correct answer choice. This would be an instance of a Mistaken Reversal. We know that a great work of art will be one that expresses an emotion, but do we really believe that every time someone puts paint to canvas while extremely happy (or extremely sad) a great work of art is going to emerge? Certainly not: the diagramming above will remind us that the starting point is “if a work of art is great….” An artist can be ecstatic and nevertheless turn out a mediocre piece. This answer choice could be false, so it is gone.
Answer choice (D): This is the correct answer choice. Based on the contrapositive of our inference above, we can see that if a entity cannot experience deep emotion, then that entity cannot produce great works of art. This answer choice discusses computers that have no emotion at all, but any entity incapable of experiencing a single emotion would be incapable of experiencing the deep ones. This choice is confirmed by the facts of the stimulus, so it is the correct answer.
Answer choice (E): The claim here is basically that the products of great artists are limited to artworks that express deep emotion. This claim deviates significantly from the conditional statement in the first sentence, which only talks about great artworks, not great artists. Since the stimulus does not support this assertion, so this choice can be ruled out of contention.
