Question

1. what institutional feature of the republic most directly helps political power? separation of powers and its accompanying system of checks and balances, 2. name one advantage and one risk associated with the empire’s concentration of authority.

Explanation:

For the second question (about the Empire’s concentration of authority):

• Advantage: A concentrated authority can enable quick decision - making and efficient implementation of large - scale projects or policies. For example, in times of crisis, an emperor with concentrated power can mobilize resources rapidly without the need for lengthy deliberations among different branches or groups.
• Risk: Concentration of authority can lead to abuse of power. The ruler may make decisions that are self - serving or oppressive towards the people, as there are few or no checks and balances to limit their actions. Also, if the ruler is incompetent or corrupt, the entire empire may suffer as there is no effective mechanism to correct or replace them easily.

Answer:

Advantage: Enables quick decision - making in crises.
Risk: Prone to abuse of power by the ruler.
