Final answer:
The common factor in a dictatorship but not in a democracy is a single person making laws. Dictatorships have a single leader with complete power, while democracies involve elected officials and the protection of human rights. Democratic systems strive for equal voice and justice for all citizens.
Step-by-step explanation:
Characteristic of a Dictatorship
The factor that is common in a dictatorship but not a democracy is a single person making laws. In a dictatorship, power is held by a single person or a very small group, and they exert complete and absolute authority over the government and population. This contrasts with a democracy, where officials are elected to represent the people and there's a respect for human rights. A constitution in a democracy outlines the foundational ideas of governance, aiming to protect citizens' basic rights, while in a dictatorship, those liberties can be limited or even eradicated.
In a democracy, the citizens typically have the power to vote for their officials and influence laws; this participative governance model is designed to protect basic human rights and prevent the concentration of power. In contrast, a dictatorship often sees economic and military might used to maintain the ruler's power, sometimes involving intimidation and brutality. Democratic ideals promote justice and equality, which is why many societies strive to evolve from monarchies or dictatorships into more democratic systems.
