← HistoryWhich risk was MOST greatly reduced allowing elaborate Mughal pietra dura inlay due to developing which adhesive application within waterworks?
A)Differential thermal expansion cracks✓
B)Sediment accumulation in pipes
C)Groundwater table contamination
D)Aqueduct wall structural failure
💡 Explanation
Less differential expansion cracking allowed the insertion of detailed pietra dura decorations, because lime-based mortar reduces stresses, rather than Portland cement used much later; therefore it accommodates expansion due to temperature rather than causing detachment due to mismatched rates.
