Which sentence correctly describes a characteristic of the parthenon?

Options:

4. The architectural plan is based on mathematical ratios, symmetry, and proportion.

Explanation:

    Parthenon is the name of a temple, built in the 5th century BC in Acropolis, a mountain located in the center of Athens, whose structure, despite the weather, conflicts and pollution, is still preserved. The word Parthenon means "the virgin's room," and the purpose of such a building was to pay tribute to the goddess Athena.

    The project is by the architects Ictinus and Calícrates, which are based on the precepts of Doric architecture, whose main feature is the use of fluted round-shaped columns with a square plate on top.

    All seemingly straight lines of the Parthenon are actually slightly curved. To compensate for the eye's tendency to see the middle columns thinner than they actually are, the solution found was to arch each one, which was also slightly slanted inward. As a final refinement, the columns at the corners of the temple are thicker, as they receive more sunlight than the others, and would look thinner if such an arrangement were not made.

    The Parthenon is considered a work of great purity and perfection.
