Strengthen with Necessary Premise Questions

Answer choices

  1. A
    Artists who take still Remaining source text redacted.
    Why choice A is not credited
    Incorrect. The argument is about understanding the world, not attempts by the artist to understand the world. If anything, Deborra sets up this argument to be about the viewer's attempts to understand. This answer is out of scope.
  2. B
    The functioning of the Remaining source text redacted.
    Why choice B is not credited
    Incorrect. If functioning can be captured on film, it's possible that still photography still might lack the ability to understand if that functioning doesn't convey narration, so this answer isn't necessary.
  3. C
    The art of still Remaining source text redacted.
    Why choice C matches the stem
    Correct. Argument or Facts:

    Question Type:
    Strengthen with Necessary Premise

    Stimulus Summary:
    Understanding → Pushing past looks into reality → Reality in function → Function takes place in time → Narration
    Short version: Understanding → Narration
    Therefore, still photography can't help us understand.

    Answer Anticipation:
    The stimulus states that understanding requires narration (both through the chain and through the final clause). The conclusion is that something can't help us understand. Taking the contrapositive of the final clause, we get:

    not Narration → not Understanding

    So to reach that conclusion, we need to know that still photography doesn't involve narration.
    Answer Explanation:
    Exactly the prephrase. When a stimulus includes a chain of connections, map it out and find the missing connection.

    Key Takeaway:
    For Assumption questions that feature a chain of connected ideas, map it out! It should help you see where the gap is. Compare it to the conclusion—the gap might be between a term in the conclusion and the start or end of the chain.
  4. D
    A complete understanding of Remaining source text redacted.
    Why choice D is not credited
    Incorrect. This answer is too expansive. The stimulus is just about still photography, not all art; the stimulus is about understanding the world, not necessarily a complete understanding. This answer may be sufficient, but it's not necessary.
  5. E
    Images cannot be properly Remaining source text redacted.
    Why choice E is not credited
    Incorrect. This answer is too expansive in talking about images instead of just still photography. While the stimulus does talk about images, it makes a point of saying that images are not where reality lies, but that's different than talking about a proper explanation.
