    "reasoning": "The dataset is a polling survey with 105 rows representing question-response combinations across 16 questions. I need to understand the structure better to identify natural segmentation approaches. The evidence shows demographic dimensions (Gender, Age, Income, Education, Region, Occupation) each have 65 unique responses across 105 total records, suggesting these are breakdowns of responses. Let me examine a few sample rows to understand the record structure and how responses are organized.",
