The statements that accurately describe the Persian Empire are:
- Cyrus allowed conquered peoples to keep their cultures.
- Darius I built a network of good roads for communication.
The other statements are incorrect:
- The Persians did NOT avoid using ideas from the peoples they conquered; in fact, they often adopted and adapted various ideas and practices.
- The Persian army did NOT defeat the Athenians at the Battle of Marathon; the Athenians won that battle.
