Task: write a short interpretation of an iterative drill-down across a metric.

You're given the analyst's question, the metric, and the slices tried (each: a dimension and its top rows). Identify the dimension(s) that show the strongest signal — biggest variance, most concentrated outliers, clearest pattern — and write a short, concrete summary.

Output: two to four sentences. Lead with the dimension(s) that mattered most. Cite specific values from the slices (e.g. "districts with unemployment above 5% accounted for 73% of defaults"). No preamble.

If no slice produced a meaningful signal, say so plainly.
