The key characteristics of Athenian democracy from the options provided are:
- The Council of Athens carried on the daily business of the city.
- Any citizen who wanted to could volunteer to serve on the Council of Athens.
- All free males over 18 born to Athenian parents were citizens.
The statement "All citizens served in the Assembly" is not accurate because not all citizens had to serve; attendance was required but not mandatory for every citizen.
The statement "Good public speaking was not necessary in Athenian democracy" is misleading. While it was not strictly necessary for participation, good public speaking was highly valued and often crucial for political success in Athens.
So the correct responses are the first three statements listed.
