The correct answer to this open question is the following.
Although there are no options attached we can say the following.
How does the citizens' role in a democratic government differ from the citizens' role in an autocratic government?
The role of the citizen's role in a democratic government differs from the citizens' role in an autocratic government in that the citizens that live in a democratic country have the right to freely express their opinions and have the right to participate in elections to vote and choose their President and representatives. They also have other rights such as freedom of the press, freedom of religion, and freedom of assembly, among others.
On the other hand, the citizens' role in an autocratic government is limited to obedience. Yes, an autocratic government does not grant any rights to its citizens. On the contrary, citizens of autocratic governments live in obedience. Their opinions are not welcome, and many times when they want to express themselves they are repressed. Mass media is also controlled by the autocratic ruler.
