How did slavery differ in the Americans compared to Africa or Europe?

Slavery in Africa was often the product of conflict and war between tribes. Unlike in America, it was not based on race. Slaves were not able to travel freely in Africa, but they experienced greater freedom within the tribal compound than American slaves. Slaves in Africa were also not necessarily enslaved for life.

Explanation:

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
