Two things that increased american interchanges in the late 1800s were "b. the telegraph and telephone," since both of these creations significantly accelerated correspondence and made it more productive.
Because back In the day there was slavery and they thought that should still be a thing so they started killing and torturing black!?!?
The fact that the imperator spent a lot of resources for wars
C) The day Japan bombed Pearl Harbor
Japan bombed Pearl Harbor, Hawaii during World War II. It was the largest attack on American soil to date, and it was viewed as an act of war. It directly led to the U.S. entering into World War II.
Hope this helps!!
