    "answer": "IS2 is the supplied observation matching Sand-A, measure V and basis B1. IS3's Sand-AX result belongs to a different grade. The newer Sand-A revision uses B2, so its value of 20 does not directly answer the B1 request without a documented equivalence or conversion. Explain the changed basis and seek clarification on which report the requester intends to use.",
