    "answer": "SC2 directly documents Beta as granite in size category D, with intended use unrecorded. Alpha shares the rock type but has a different product identity and size category. Gamma is newer but concerns another product and material. Neither supplies Beta's missing use, and Gamma's category C does not override Beta's category D. No suitability recommendation follows from the catalog labels.",
