Roman arches may develop into ___________.

Roman arches may develop into ___________.

• A. Dome
• B. Cupola
• C. Arch
• D. Vault

Answer: (A)

Romans used the arch as a basic building block for larger ceiling systems, and by extending that curved form into multiple arches and joining them in a circular, shell-like arrangement, they could cover a space with a dome. A dome is essentially a curved vault that has been rotated around a central axis to form a hemispherical or spherical cap, so the arch evolves into a dome through this expansion into a vaulted, rounded ceiling. A cupola is simply a smaller dome or lantern atop a roof, not the broader development from a single arch; a vault refers to the broader family of arched ceilings; and an arch is the starting element, not the end form.
