The argument employs which one of the following

Answer choices

  1. Bad Evidence Match8% picked this

    It cites counterevidence that calls into question the accuracy of the evidence advanced in support of

    The evidence for the author's rebuttal (the new studies) doesn't attack the opposing evidence (the correlation between chocolate eating and breakouts). It's actually consistent with that opposing evidence because the studies are trying to explain that same correlation.

  2. Correct69% picked this

    It provides additional evidence that points to an alternative interpretation of the evidence offered in support of

    Why this is right

    We have additional evidence (new studies) that points out an alternative interpretation (chocolate is an effect, not a cause) of the evidence offered in support of the position being challenged (chocolate eating and acne are correlated).

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

  3. Bad Evidence Match7% picked this

    It invokes the superior authority of science over common opinion in order to dismiss out of hand the relevance of

    This one is tempting because the author does invoke new scientific studies as evidence and we do see common view language in the opposing conclusion. That said, the evidence doesn't actually say that science is superior to common views, and the conclusion doesn't dismiss out of hand the relevance of the opposing evidence.

  4. Bad Evidence Match1% picked this

    It demonstrates that the position being challenged is inconsistent with certain

    The evidence doesn't bring up any well-established facts: it brings up some new studies, which is kind of the opposite of well-established. The conclusion doesn't demonstrate that the opposing conclusion is inconsistent with anything. It just raises an alternative conclusion one might draw.

  5. Bad Evidence Match14% picked this

    It provides counterexamples to show that, contrary to the assumption on which the commonly held position rests, causes do

    The evidence doesn't bring up a counterexample or attack an assumption. And the conclusion is definitely not that causes don't always precede their effects. That's counter to common sense! In order for something to be a cause, it has to come before the effect.
