Which of the following is a way that citizens can participate in democracy?

Running for office is a significant way for citizens to actively engage in the democratic process. It allows individuals to represent their communities, voice their concerns, and influence policy-making directly. By seeking a position within the government, a citizen takes on the responsibility of advocating for the best interests of their constituents. This involvement is foundational to the democratic system, as it encourages diverse representation and enables citizens to take an active role in shaping governmental decisions and local, state, or national policies.

The other options do not inherently involve participatory actions within the context of democracy. Wearing a uniform may relate to military service or specific professions, but it does not imply active civic participation. Traveling abroad, while beneficial for personal development and exposure to different cultures, does not contribute directly to democratic engagement. Paying tolls is a civic duty related to transportation and infrastructure but does not equate to participation in the democratic process. Therefore, the option to run for office distinctly highlights an active and meaningful involvement in democracy.
