Which mechanism primarily enabled the construction of stable, multi-story ziggurats in ancient Mesopotamia?

💡 Explanation

When ziggurats were built, the 'stepped pyramid' design allowed for load distribution through stepped layers because each successively higher layer transferred weight outward and downward across a larger base area. Therefore, load distribution resulted, rather than buttressing, fiber reinforcement, or seismic isolation, which employed different mechanical principles.
