PrepTest 116

Incorrect. There's no indication that an exact copy of a painting can't impart a stimulating character to the audience's experience of it.

Incorrect. Exciting the audience is what is established as being related to aesthetic value, not the skill of the performance. (Note that aesthetics necessarily deal with beauty, so there's no shift in terms here.)

Incorrect. The rarity of the material that the art is made from is not mentioned as being related to aesthetic value, so this answer is incorrect.

Incorrect. There's no indication that being by a controversial artist imparts a stimulating character to the audience's experience. Maybe the artist is controversial because of their personal life, but their art is quite tepid.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True (Principle)

Stimulus Summary:
Aesthetic value of art ←→ Ability to impart stimulating character to audience experience

Answer Anticipation:
Most principles on the LSAT are stated in conditional terms. This one here is a little different, though we can still represent it conditionally. While it doesn't include any indicator words, it does set up an equivalency or definition—aesthetic value is related to a work imparting a stimulating character to the audience. Art that does this is aesthetically valuable, and art that doesn't, isn't. Therefore, we can represent the principle as a biconditional, connecting these two ideas in an inextricable fashion.

Don't forget that we can take the contrapositive of biconditionals, so we can pick an answer about works that aren't aesthetically valuable:
not Impart stimulating character to audience ←→ not Aesthetically valuable

Answer Explanation:
If a work has little impact on the audience, then it's not imparting a stimulating character to their experience. The principle in the stimulus thus allows us to conclude that it doesn't have aesthetic value, as this answer states. It is therefore the correct answer.

Key Takeaway:
Principles are generally applicable rules, and so they can almost always be turned into a conditional, even if there aren't conditional words explicitly stated. And when a statement creates an equivalency between two things, you should view that as a biconditional.
