    "reasoning": "The question asks about natural segmentation opportunities. The overview confirms this is a single dimension table with 171 funding deals.

Before writing SQL to explore distributions, I should check what the Industry column actually contains and how many distinct values exist, since it's explicitly called out as a spatial axis. I'll also check the date range and other categorical columns to identify the strongest segmentation candidates.",
