[单项选择]In place of the king, two chief executives were chosen annually by the whole body of citizens. These were known as praetors, or leaders, but later received the title of consuls. The participation of a colleague in the exercise of supreme power and the limitation of the tenure to one year prevented the chief magistrate from becoming autocratic. The character of the Senate was altered by the enrollment of plebeian members, known as conscripti, and hence the official designation of the senators thereafter was patres conscripti (conscript fathers). As yet, only patricians were eligible for the magistracies, and the discontent of the plebs led to a violent struggle between the two orders and the gradual removal of the social and political disabilities under which the plebs had labored.
In 494 BC a secession of plebeian soldiers led to the institution of the tribuni plebis, who were elected annually as protectors of the plebs; they had the power to veto the acts of patrician magistrates
