Which activity is a responsibility of U.S. citizens?

Voting is a fundamental responsibility of U.S. citizens and plays a crucial role in the democratic process. It allows citizens to participate in shaping their government and influencing the laws and policies that affect their lives. By voting, citizens express their opinions and preferences on various issues and select representatives who align with their values and interests. This involvement is essential for a functioning democracy, as it empowers individuals to have a voice in the decision-making processes at local, state, and federal levels.

While traveling is a right and a personal choice for citizens, it is not an obligation or responsibility. Collecting taxes is a civic duty primarily carried out by the government and not individual citizens in the sense of bearing that responsibility actively. Serving on the Supreme Court is a role designated for appointed justices, and it is not a responsibility shared by all citizens. In contrast, voting is an actively encouraged duty that underlines the value of engaged citizenship in the United States.
