Based on your question, it seems you are referencing a chart related to Roman leadership. The primary leaders in the Roman Republic were:
- Consuls: They were the elected leaders who held executive power.
- Senate: This was a political institution that provided advice and governance support but was not an executive body.
- Assembly of Centuries and Assembly of Tribes: These were the legislative bodies that represented the people and had the power to pass laws.
If the question is asking who was needed for leadership, the answer would likely be consuls, as they were the main executive leaders in the Roman Republic.
