Stimulus

Art critic: Criticism focuses on two issues: first, whether the value of an artwork is intrinsic to the work; and second, whether judgments about an artwork’s quality are objective rather than merely matters of taste. These issues are related, for if an artwork’s value is not intrinsic, then it of the work can only be a matter of taste.

What this question is testing

Necessary Assumption

Your task

Find the assumption the argument requires in order for its conclusion to hold.

Common trap

Answers that would help the argument but aren't strictly required (sufficient, not necessary).

Winning move

Negate each choice — the right one breaks the argument when negated.

Answer choices

  1. Too Strong: always9% picked this

    judgments about the quality of an artwork are always a matter

    The argument doesn't imply that quality judgments are always a matter of taste, only that "if the value of an artwork is extrinsic, then quality judgments are always a matter of taste". If the value of an artwork is intrinsic, it's possible that the author would think that quality judgments would be objective.

  2. Out of Scope: agree5% picked this

    people sometimes agree about judgments that are only matters

    Even though this is appealingly weak wording, nothing in the argument had anything to do with whether or not people agree about judgments that are matters of taste. If we negated this and said, "People never agree about judgments that are only matters of taste", it wouldn't weaken the argument at all, because the author was never concerned with whether people do / don't agree.

  3. Correct75% picked this

    judgments about extrinsic value cannot be

    Why this is right

    This provides a conditional answer, so we should think about or look at how it's diagrammed and ask ourselves whether it would match up with a reasoning move the author made: Extrinsic value ? Judgments not objective That matches up with the missing link we were predicting, "If extrinsic, then judgments are just a matter of taste". The author is treating "judgments are a matter of taste" and "judgments are objective" as mutually exclusive. So if the author thinks that judgments are just a matter of taste, this is equivalent to saying that judgments are not objective.

    Skill tested: Necessary Assumption · how this choice captures the argument's function is the move to repeat next time.

  4. Too Strong: always Illegal Negation8% picked this

    judgments about intrinsic value are always

    The author doesn't need to assume the extreme idea that all judgments about intrinsic value are objective. This answer is an illegal negation of the missing link. We were looking for: if value is ? then judgments are extrinsic just matter of taste This answer is saying: if value is ? then judgments are not extrinsic not just matter of taste But this answer disguised the illegal negation it was doing by re-writing "not extrinsic" as "intrinsic", and writing "not a matter of taste" with "objective".

  5. Not Necessary4% picked this

    an artwork’s value is sometimes intrinsic

    This is appealingly weak wording, but it's not a necessary idea. If we negate this, it will say "an artwork's value is never intrinsic to it". That means that an artwork's value is always extrinsic, which means that judgments about quality are only a matter of taste, which means that "the issue of whether value is intrinsic / extrinsic is related to the issue of whether judgments are objective / matters of taste." In other words, negating this answer wouldn't weaken. In fact, the negation seems more like a strengthener.
