Answer:
When the Italian explorer Christopher Columbus inadvertently discovered the Americas, it became known as the New World.
In a series of activities which were mostly commercial in nature for the benefit of Europe, crops (such as sugar, tobacco, chocolate, and potatoes), animals (such as horses), European culture, human populations (both slaves and colonial masters), technology, diseases, and new ways of doing things were exchanged between the "New World" and the "Old World"
In order to make for smooth colonial administration between the African leaders and the Colonial masters, African leaders were bribed with textiles, rum and manufactured goods from Europe.
Slaves were transported from Africa to the Americas to work on plantations of sugar , tobacco and cotton which were then transported to Europe.
This trade is what came to be referred to as the Columbian Exchange.
Europe is said to have benefited more from the Colombian Trade, as there has been a huge shift of resources to Europe , especially gold and silver from the New World and other regions.

As an undergraduate studying psychology, my intended major is crime investigation.
I started having interest in this field since the day my uncle's was convicted for a crime he did not commit, just because he pleaded guilty due to the pains that was inflicted on him to do so and be free in jail. I felt this should not be a proper way to investigate crime. That is why I was motivated to major in this field, so as to bring the change needed in the field.
Sometimes I practice this investigation, using my younger siblings. It has helped me to understand that empathy is still important in crime investigation, even though it sometimes makes us feel biased. I have become the only one my parents rely on, to determine who among my siblings that has committed an offence during dispute.
