Final answer:
Aspects of Athens' political system that made it more democratic included the expansion of participation and the emphasis on equal justice.
Step-by-step explanation:
Steven describes Athens as the birthplace of democracy, although limited in nature. Beth mentions a series of reforms in the fifth century that expanded the participation of people in the government. Pericles, in Thucydides's History of the Peloponnesian War, praises the Athenian constitution for allowing all members of the state to participate in its governance. These aspects of Athens' political system, including the expansion of participation and the emphasis on equal justice, made it more democratic compared to the source's account of Athens' political system.
