You need to put what all the following are or I can't help.
A. Spanish conquistadors bring their horses with them across the Atlantic. Some horses escape or swim to shore after a ship sinks. The Plains Indians become expert horsemen and buffalo hunters.
This was certainly not intentional since hardly the conquistadors would want their enemies to be stronger.
B. B. Rats are aboard European ships coming to the Americas. The rats spread disease and hunt unknown numbers of smaller animals to extinction.
This is hardly intentional. Rats were almost unavoidable back then and the Europeans just did not care much about them. They weren't thinking about how the rats would cause trouble in the Americas. They were "just rats".
So the only intentional one is:
C. Columbus brought pigs to the Americas on his second voyage. The pigs provided a valuable source of food for a growing population.
Columbus brought pigs for them to serve as food eventually and so they did.

The intersection between the supply curve (an upward sloping function) and the demand curve (a downwardsloping function) determines the equilibrium point of a market. The equilibrium is the point which represents the exact market price and quantity demanded/supplied at which the wishes of consumers and suppliers meet.
<u>When the market is not in the equilibrium point</u>, two different situations could be happening:
- Excess demand: this is a situation in which the market price is located below the equilibrium price. The quantity demanded at that market price would exceed the amount that the producers are willing to produce and supply at that same price. Therefore, not all consumers are able to obtain the product they desire and there is rationing.
- Excess supply: at a certain price located above the equilibrium, the quantity that suppliers are willing to produce exceeds the amount demanded by consumers at that more expensive price. Therefore, suppliers would not be able to sell their whole production in the market.
