    "answer": "EA2 supports 80 at district grain, with its included school rows 30+50 reconciling to that total. Adding all three rows would double-count the same population. EA3 also makes C2 different from C1, so 100 to 80 is a reported difference across cohorts rather than a supported like-for-like decline. Preserve year, grain and definition, and request a common-cohort series for that interpretation.",
