Which consequence resulted when late Roman fortifications improperly implemented opus caementicium?

💡 Explanation

Increased ground saturation causes liquefaction because grain rearrangement reduces friction; therefore, instability leading to collapse occurred, rather than other structural benefits, because construction flaws accelerated environmental infiltration.
