The statements that describe classical Greek architecture are:
- pediments, or triangular ends on roofs
- symmetry and balance
- columns that swell in the middle and taper at the top
Classical Greek architecture is characterized by its use of pediments, a strong emphasis on symmetry and balance, and the iconic columns that display specific proportions, such as the swelling in the middle (entasis) and tapering at the top.
The other options, "tapering spires on top of towers" and "rounded arches," are more commonly associated with Gothic or Roman architecture rather than classical Greek architecture.
