During a Roman siege, which consequence arises from undermining a city wall's foundation, potentially leading to its catastrophic failure?

💡 Explanation

Undermining a wall compromises its structural integrity because soil removal reduces the shear strength holding the foundation together, therefore the wall is unable to resist lateral forces and collapses, rather than distributing load effectively or exhibiting enhanced resistance.
