Passage Summary: Some artists think they should only model their work on things in the real world, but the author believes it's a waste of talent to only copy things that would exist even if the artist didn't.

Conclusion: It is an ironic waste for artists to use their skills exclusively to represent and reinforce objects that exist independently of the artist.

Reasoning: While art can make external objects beautiful, focusing solely on the external world ignores the internal psyche and fails to utilize the full potential of artistic representation.

Analysis: To identify the conclusion here, we look for the author's main point or value judgment. The first sentence introduces a 'mistaken' belief held by many artists, which serves as a foil for the author's actual stance. The second sentence provides the author's verdict, using the evaluative phrase 'ironic waste.' This normative claim is the conclusion because the rest of the passage is designed to lead the reader to this specific rejection of purely external modeling. In 'Identify the Conclusion' tasks, always look for the statement that expresses the author's primary opinion or the 'point' they are trying to drive home.
