Asystem involves the direct exchange of goods and services without the use of money as a medium of exchange.

The correct answer is: "BARTER"

Barter is a system of exchange that does not involve the use of money. It was the manner of conduting trade that was used in ancient civilizations until money was invented in China in the seventh century. It consists on one party that exchanges goods and services that needs and does not have, for others that that a different party has and does not need. These exchanges require a time-consuming process of finding two parties which are interested in performing each specific exchange.

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)

ok
