Which problem was overcome for Pont du Gard stone stability, leading to long-term structural integrity?

💡 Explanation

The stone material was carefully selected and placed, accounting for differential EQUILIBRIUM because thermal expansion would create stresses within individual blocks. Therefore, the arrangement stabilized the entire structure, rather than the alternatives involving construction techniques applicable at a base level.

• Which outcome results when thermal expansion mismatch influences subsurface 'pietra dura' inlay placement within Mughal architecture?
• Which outcome results from misalignment of the alidade on an astrolabe when measuring the altitude of a star?
• Which consequence arises in ancient terrace farming when walls degrade?
• Which outcome predictably occurred when 18th-century ships excessively heeled?
• Which risk increases when using thinner marble in pietra dura on Mughal monuments?
• Which defensive failure would be amplified by a Roman fort’s reliance on a glacis?
