The reason why U.S dropped an atomic bomb on japan was due to world war two even though the they lost the wouldn't surrender at all the choose to fight so the y had a plan
I believe that immigrants migrated to the United States because of the abundance of resources and work opportunities. Many also fled from wars and sought safety for their families and themselves. Difficulties that immigrants from the 19th century faced ,and still face now, was the idea of Racism and also how society saw them. Many also had trouble finding places to live or people to communicate with. Many formed small groups and communities to stay together with the people of their own race and culture for safety.
Either c or b hope that helps
