Which risk increases where Inca stone aqueducts exhibited differential settling?

💡 Explanation

Increased shear stress arises at mortar joints because differential settling induces uneven stresses across the aqueduct structure, impacting stability; therefore, structural integrity is reduced, rather than cryogenic fracturing of aggregate influenced by ambient cold influencing individual blocks.
