Which one of the following, if true, most weakens

Answer choices

  1. Correct86% picked this

    A text that was probably known to both Jordan and Grey was published in 1860 and also contained

    Why this is right

    This suggests that both authors took the metaphor from a third text, predating both of their books. It provides an alternate explanation for the curious fact, effectively weakening the conclusion that Gray stole it from Jordan.

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

  2. No Impact10% picked this

    The passage in Grey’s book that employs the unusual metaphor expresses an idea that bears little relation to any

    This points out that Gray uses the metaphor to express a different idea, but metaphors can be used in various contexts without suggesting original authorship, thus not effectively countering the conclusion.

  3. Strengthens (if anything)1% picked this

    Both Grey’s book and Jordan’s book were written for the

    This states that both books targeted the same audience, potentially supporting the idea that Gray could have been influenced by Jordan's prior work, subtly aligning with the conclusion.

  4. No Impact1% picked this

    Jordan used the same metaphor in a work that she wrote in 1894 and

    This indicates Jordan used the metaphor repeatedly in her subsequent writings, which doesn't suggest an alternative source or impact the possibility that Gray copied it from her original use.

    According to most scholars, Grey was generally a more inventive writer than Jordan and developed

    This implies that Gray was more inventive and potentially could have originated the metaphor, suggesting an alternate narrative. However, even if Grey was more likely to develop an original metaphor, the author's point is that it's crazy unlikely that two different people would separately invent this same metaphor, and we know Jordan's use of it was published first.
