Final answer:
The Roman method of construction that broke down tasks into simplified, repetitive actions is known as standardization. This allowed for efficient building of structures like the Colosseum, featuring arches and assigned seating, akin to the modern assembly line.
Step-by-step explanation:
The construction method used for the Colosseum, where tasks were simplified and repeated over and over again, is known as standardization. This method contributed to the Colosseum's efficient building process. Typically called an assembly line in modern times, the old Roman method of standardization allowed for faster construction while maintaining consistency throughout the building process. The Colosseum, with its arches and use of concrete, symbolizes the innovation of Roman architecture. This structure was built with such precision that tickets would have numbers corresponding to assigned seating in the arena, very much like modern stadiums. The arches were also crucial in supporting the weight and allowing for the grandeur of the Colosseum and other Roman buildings, like aqueducts and vaults.
