What borders mexico on all four sides of its sides

On the East you have the Gulf of Mexico that merges with the Atlantic Ocean.

 On the West you have the Gulf of California, which merges with the Pacific Ocean.

North of Mexico, when looking at a map, the part that separates Texas from Mexico, there is the Rio Grande.

Down South, you have Guatemala and Beliz, which also borders Mexico.

Hopefully this helped and good luck. I don't know how technical your teacher wants your answer to be, so I tried to be technical that way he/she cannot say you're wrong in your responses. Once again, good luck.

the answer is d. party organizers, volunteers, voters and elected officials.

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)
