Which outcome occurs when a Roman fort's foundations experience differential settling?

💡 Explanation

Differential settling weakens mortar, causing arch barrel vault cracking due to structural stress. Keystone displacement occurs because load bearing shifts across the weakened structure, therefore overall stability fails, rather than corrosion/range changes.
