Final answer:
The argument that the Roman Republic was a democracy is supported by the fact that adult male citizens, including the poor and freed slaves, had voting rights, leading to the answer (d) All of the above.
Step-by-step explanation:
In discussing the extent to which the Roman Republic was a democracy, Fergus Millar made several arguments regarding the nature of voting rights during that time. These included that adult male citizens, unless disqualified, could vote; that the poor were not formally excluded from the process; and that freed slaves could also participate in the voting process.
Thus, the answer to the student's question is (d) All of the above. This inclusive approach to suffrage in the Roman Republic, however, was not without its limitations, as women and non-citizens, including slaves, were not afforded voting rights.
