Raj: Dogs that have been traditionally used for violent tasks should not be kept as pets. Hardly a day goes by when the newspapers do not feature a story where a child has been mauled by a Pit Bull or a Rottweiler. These animals' innate desire to attack and guard make them an unmitigated danger to young children who might accidentally cause the animal to feel threatened. Melanie: That is an unfair assessment of these animals' character. Any innate traits that have been acquired through breeding and bloodlines can be overcome by proper training and discipline. For instance, many Bloodhounds, known for their hunting ability, have been trained to not attack rabbits or squirrels. The statement that Bloodhounds have been trained to not attack rabbits or squirrels plays which of the following roles in Melanie's argument? ['It offers a counterexample to illustrate the general conclusion.', 'It is offered as supplementary proof that no dogs have an innate desire to attack and guard.', "It provides support for Melanie's argument that also inadvertently strengthens Raj's argument.", 'It offers a theory that harmonizes both the stated position and the stated conclusion.']
