Raj: Chiropractics should be outlawed in this state as treatment for neck pain; physicians have presented evidence that there is a link between neck manipulations and strokes. Nancy: You are correct in pointing out that neck manipulations have been linked to strokes. However, this risk only exists when the practitioner gives the neck a high-velocity twist. If there were better established requirements of using less forceful techniques for neck manipulations, then chiropractics would be a safe and effective treatment for neck pain. Nancy does which one of the following in responding to Raj's argument? ['She defends an opinion by limiting the set of circumstances to which it is to be applied.', "She points out that Raj's argument itself creates the objectionable quality that it denounces.", 'She refuses to acknowledge the facts that Raj uses to support his argument to be true.', "She establishes that Raj's premises are self- contradictory."]
