Wall bulge → Broken joist Wall bulge Therefore - Broken joist

Answer Anticipation

This argument establishes a general rule (“The only”) that we represent as a conditional. It then shows that the sufficient condition was met, and it concludes the necessary condition. All in all, this is a pretty standard argument that applies a conditional to a specific case, so let’s find an answer that does the same.

Answer choices

  1. A
    At least one of Remaining source text redacted.
    Why choice A matches the stem
    Conductor grimace → Player made a mistake

    Conductor grimace

    Therefore - Player made a mistake

    This answer follows the same pattern, so it’s the correct answer.
  2. B
    The first piece must Remaining source text redacted.
    Why choice B is not credited
    This argument jumps between easiest and not making mistakes, which is a flawed jump. This argument isn’t valid, as the stimulus is, so we can rule it out.
  3. C
    The players play well Remaining source text redacted.
    Why choice C is not credited
    The conclusion here is conditional, so it doesn’t match up with the stimulus where the premise was conditional.
  4. D
    One of the orchestra's Remaining source text redacted.
    Why choice D is not credited
    The premise here is about what “should” be done, so it’s logically distinct from all of the premises in the stimulus.
  5. E
    The emotion of the Remaining source text redacted.
    Why choice E is not credited
    There’s only one premise, and it’s not conditional, so this answer isn’t parallel to the stimulus.
