Mark the statements which are true. the difference between the roman republic and the greek democracy was that: in rome, only men with money and property could vote. in the greek senate, even teenagers were allowed to participate. in the roman government, no greeks were allowed to serve. in greece all men were allowed to vote. in the roman senate, the most powerful part of the government, all senators were patricians. in the greek government, retired soldiers were given automatic seats in the senate.
