A museum conservation board classifies historical artifacts into three management streams based on two parameters: Material Sensitivity (High or Moderate) and Structural Fragility Index (a numerical score from to ). The classification rules are defined as follows:
- Track Y (Long-Term Preservation): Assigned if an artifact has High Material Sensitivity AND a Structural Fragility Index score of at least .
- Track X (Immediate Stabilization): Assigned if an artifact meets EXACTLY ONE of the two conditions (either High Material Sensitivity OR a Structural Fragility Index score of at least , but not both).
- Routine Storage: Assigned if an artifact meets NEITHER condition (Moderate Material Sensitivity AND a Structural Fragility Index score below ).
Match each of the following three artifacts to its correct management stream.
- Artifact Alpha: High Material Sensitivity; Structural Fragility Index of 75Track Y (Long-Term Preservation)
- Artifact Beta: Moderate Material Sensitivity; Structural Fragility Index of 82Track X (Immediate Stabilization)
- Artifact Gamma: Moderate Material Sensitivity; Structural Fragility Index of 50Routine Storage
