Passage Summary: Carl thinks it's weird that animals get legal pain protections while humans don't. Debbie argues that humans don't need those laws because humans can talk to their doctors and give consent, which animals can't do.

Conclusion: Legal pain protocols are not required for human surgeries.

Reasoning: Unlike animals, human patients can be informed about potential pain by their doctors and can choose whether or not to proceed with a procedure.

Analysis: Debbie counters Carl by identifying a fundamental difference between the two subjects being compared. Carl's argument rests on an analogy between humans and animals, implying they should be treated similarly by the law. Debbie breaks this analogy by pointing out that humans have the capacity for informed consent, a feature that makes the 'missing' protocols unnecessary. Look for an answer that describes her method as pointing out a relevant difference that justifies treating the two cases differently. She isn't saying Carl is wrong about the laws; she's saying he's wrong about why the laws are different.
