Passage Summary: Since great writers usually understand society well, it must be true that as a writer gets better, their understanding of society must also get better.

Conclusion: A writer's level of social and political astuteness is directly proportional to their greatness as a writer.

Reasoning: Great artists and writers generally possess a discerning view of the social and political arrangements of their society.

Analysis: This argument makes a 'degree' or 'proportionality' error. Just because a trait is common among a group (great writers), it doesn't mean that the trait scales perfectly with the quality of the work. It's like saying 'Tall people are generally good at basketball, so the taller you are, the better you are at basketball.' It ignores other factors and assumes a linear relationship that isn't proven. Look for an answer that describes the mistake of treating a general characteristic as a proportional scale.
