    "reasoning": "I need to identify the main categorical columns and find their most common values with frequencies. From the evidence, I can see that step-1 already provides frequency distributions for several columns (Additional_Recognition, Champion_Name, Days, End_Reign, Title_Defenses), but the data appears mixed and incomplete. The column names in step-1 don't match the actual schema - 'Champion_Name' isn't a real column (the actual column is 'Champion'). I need to write a proper SQL query to get the most common values for the key categorical columns: No (champion names), Champion, Recognition, Begin_reign, End_reign, Days, Title_defenses, and Additional_recognition. I'll create a comprehensive query that shows top values for each categorical column.",
