    "answer": "FDD1 supports A's net mass of 30 and measured fill volume 15, giving two practice mass units per volume unit. FDD2 confirms B's net 28 but gives capacity rather than actual fill volume, so 28/20 would not be a supported measured density. FDD3's shared name cannot transfer A's observed fill or formulation. Preserve package, run and measurement type rather than derive an unsupported comparison or real quantity claim.",
