A the arch

A - the arch

The correct answer is A. the arch.

To understand why the arch allowed the Romans to make larger enclosed buildings than the Greeks, we need to understand the basic structure of an arch. An arch consists of a curved shape supported by two vertical posts called columns. This curved shape distributes the weight of the structure more efficiently, allowing for larger and more expansive buildings.

So, to find the answer to this question, you would want to compare Greek and Roman architecture and identify the difference that allowed the Romans to build larger enclosed buildings. One way to do this is by studying the architectural features and techniques used by both civilizations.

The Greeks primarily used a post-and-lintel system, where horizontal beams (lintels) were supported by vertical columns. This system worked well for smaller buildings, but it had limitations when it came to spanning larger spaces.

The Romans, on the other hand, perfected the use of the arch in their architecture. By using curved arches, they could create vaulted ceilings, which allowed for larger enclosed spaces. The arch could distribute the weight more efficiently and transfer it to the supporting columns or walls on either side.

So, based on this understanding, the correct answer is A. the arch.
