Why did the crew of the zong ship throw some captive africans overboard?

they threw them overboard because they were too stubborn for example: the slave traders yell to row the boat but they're either tired or to weak to row and since they're either tired or weak they don't row as fast or as much and then the slave trader gets really mad causing him to throw the captives overboard to teach the others a lesson. or he'd throw them over to send someone else a message but #1 was a better example

disequilibrium means that either supply is greater than the demand for an available good, or that the demand for a product outstrips the available supply. it implies that the price for a is either too low creating large demand, or too high creating a large surplus of supply.
