Even those who believe that the art of each age and culture has its own standards of beauty must admit that some painters are simply superior to others in the execution of their artistic visions. But this superiority must be measured in light of the artist' s purposes, since the high merits, for example, of Jose Rey Toledo' s work and his extraordinary artistic skills are not in doubt, despite the fact that his paintings do not literally resemble what they represent. The claim that some painters are superior to others in the execution of their artistic visions plays which one of the following roles in the argument? ['It is a claim that the argument derives from another claim and that it uses to support its conclusion.', 'It is a claim that, according to the argument, is to be understood in a manner specified by the conclusion.', 'It is a generalization, one sort of objection to which the argument illustrates by giving an example.', 'It is a generalization that the argument uses to justify the relevance of the specific example it cites.']
