    "reasoning": "I have strong evidence of a counterintuitive pattern: Biotech has 2x the deal count (42 vs 21) but AI raised 2.3x more total funding ($15.8B vs $6.7B), meaning AI deals average ~5x larger. Before finalizing, I need to: (1) verify these are the top 2 industries by deal count, (2) calculate exact average deal sizes to quantify the gap precisely, and (3) check if any mega-deals skew AI's average or if this is a consistent pattern. This will make the finding concrete and rule out that it's driven by one outlier.",
