Answer: Voting & Jury Duty
Explanation: Voting: One of the fundamental responsibilities of a U.S. citizen is to exercise their right to vote. Citizens have the privilege and duty to participate in the democratic process by casting their vote in local, state, and national elections. Voting allows citizens to have a say in the governance of their country and helps shape the direction of public policy.
Jury Duty: Another important responsibility of U.S. citizens is to serve on juries when called upon. Jury duty is a crucial component of the justice system, as it ensures that individuals are judged by a fair and impartial group of their peers. Citizens may be randomly selected and summoned to serve on juries, where they are expected to review evidence, deliberate, and contribute to the decision-making process in legal cases.
