Which action is considered a mandatory responsibility of us citizenship?

holding political office
serving in the army
serving on a jury
joining a political party

serving on a jury

Explanation:

For the American people, participation in a jury is the duty of every citizen. This duty is constitutionally enshrined as the bulwark of citizens' freedom, since for Americans the exercise of democracy by the participation of the people in public life occurs not only by practicing the right to vote, but also by the performance of the right to integrate Jury court.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
