← HistoryWhich mechanism limits pattern precision when cutting 'pietra dura' on 17th-century Mughal structures?
A)Cumulative abrasive particle deflection✓
B)Differential thermal stone expansion
C)Inconsistent gemstone impurity distribution
D)Uncalibrated sandstone cutter offsets
💡 Explanation
Abrasive particle deflection is the limitation because non-rigid tools accumulate errors via gradual drift, therefore precision is reduced rather than from inherent stone properties or thermal effects, causing progressive deviations.
