Although you forgot to include the text, doing some research we can say that the statement that best expresses the central idea of the text is "The ancient Greeks built temples to honor their gods, but the Parthenon built for Athena is particularly detailed."

Ancient Greeks built impressive temples that were dedicated to their gods. Greeks always had a love and hate with the ample pantheon of gods they had and supposedly lived in Olympus.

However, talking specifically about the Parthenon in Athens, Greece, it was dedicated to goddess Athena and archeologists and architects consider it a real monument of ancient architecture due to its construction characteristics and fine details.
