Answer choices

  1. A
    A culture without myths Remaining source text redacted.
    Why choice A is not credited
    Incorrect. The conclusion here isn't really conditional. Instead, this argument tries to apply a conditional to a specific case.
  2. B

    Why choice E matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Flawed

    Question Type:
    Flawed Parallel Reasoning

    Stimulus Summary:
    Eloquent speaker-some-Impress audiences with messages
    Obscene speaker → not Eloquent speaker
    Therefore: Obscene speaker → not Impress audiences with messages

    Answer Anticipation:
    There are a few flaws with this, and it can be difficult to pin down exactly how to describe them since the combinations drawn from here involve contrapositives and flawed conditional/quantified inferences. However, we don't have to describe the flaw, we just need to find an answer that makes the same flaw. Since this argument features conditionals and quantified statements, and the flaw is related to them, we can look for an answer that follows the same pattern:

    A-some-B
    C → not A
    Therefore: C → not B

    Answer Explanation:
    This answer at least has all the right parts, so we should dive in:
    Sculptors-some-Produce significant art
    Musicians → not Sculptors
    Therefore: Musicians → not Produce significant art
    Same structure, so same flaw.

    Key Takeaway:
    In a Flawed Parallel Reasoning question, when there's a complex flaw related to conditionals and quantified statements, you don't need to precisely define the flaw. As long as you know that it's related to those statements, you can find an answer that diagrams out in the same manner and, thus, must have the same flaw.
