Final answer:
The two primary differences between a democracy and an authoritarian system are the voting process and leader selection, as well as civil rights and government control.
Step-by-step explanation:
In a democracy, the voting process and leader selection are done through free and fair elections where citizens have the opportunity to choose their representatives. In an authoritarian system, the voting process is either absent or manipulated to ensure the selection of a specific leader or ruling party. Civil rights and government control are also two key differences between the two systems. In a democracy, citizens enjoy a wide range of civil rights and freedoms, such as freedom of speech, assembly, and religion. The government's power is limited and subject to the rule of law. On the other hand, in an authoritarian system, civil rights may be restricted or violated, and the government exercises strong control over society.
