precarious matches 'Insecure, hazardous, and dangerously unstable'; substantiate matches 'To verify or prove true with concrete evidence'; perfunctory matches 'Superficial and hurried without careful attention'; resilient matches 'Capable of recovering shape and strength after stress'.
Each bolded word is defined by specific context clues in its sentence: 'precarious' is supported by descriptions of frayed cables and violent swinging; 'substantiate' is framed by the need for sensor data to validate a suspicion; 'perfunctory' is directly contrasted with 'exhaustive'; and 'resilient' is defined by the material's ability to resist deformation under high pressure.
