The Americas! The discovery of the new world opened up a new output for products like gold and silver. (Especially silver for Spain) The Columbian exchange resulted in foods such as the potato being brought over to Europe. Did you know the first potatoes were actually from Peru! Labor animals like cows and bulls were brought over to the new world. This was basically the only good thing about the Columbian exchange for the AMericas. Europe mostly just gave the Americas disease and death.
B. Immigrants left Ellis Island within hours; they often remained in Angel Island for weeks.
Immigrants in Angel Island came from Asian countries, specifically, China, Japan, Russia, and South Asia. Upon arriving in Angel Island, they have to undergo medical examination and interrogation process.
The length of time an immigrant spend on Angel Island varies on the length of his or her interrogation process. Some immigrants produce false paperwork, which lengthened their interrogation process because the authenticity of said paperwork must be verified before they can be granted entry to the United States.
Let's start off with what a brief explanation of what social stratification is; Social stratification is a persons ranking in society. Whether it be financial wise (the most common), the age group, education, and even family power. An early form of this could be the Roman Empire's hierarchical structure; they had the lowest class which would be the slaves and then would work their way up to the highest class which would be the Emperor.
I hope this helped.
