Which form of government allows people to vote directly on policy initiatives?

The correct answer is direct democracy, as this system enables citizens to engage in decision-making by voting directly on policy initiatives and legislation. In a direct democracy, there are no intermediaries such as elected officials that represent the people's choices; instead, the people themselves propose and vote on laws and policies, which is a feature seen prominently in some local governments and certain Swiss cantons.

This form of governance is distinguished from representative democracy, where citizens elect officials to make decisions on their behalf. Autocracy refers to a system of government where a single person holds absolute power, which restricts the public's ability to vote or influence policies. Oligarchy describes a government run by a small group of people, often leading to limited participation from the wider population in the decision-making process. In summary, direct democracy is uniquely focused on allowing citizens to vote directly on policies, setting it apart from the other forms listed.
