I'm assuming you meant the civil war so the answer to that would be The Battle Of Gettysburg.
Answer:
the Fugitive Slave Act was amended and the slave trade in Washington, D.C., was abolished. Furthermore, California entered the Union as a free state and a territorial government was created in Utah.

The correct answer is: "a supply curve"
The supply curve is a function that represents different combinations of prices and quantities. Those quantities, are the amounts that producers of a certain good or service are willing to manufacture and/or sell at each price level.
It is an upward-sloping function as, according to the law of supply, the higher the market price, the larger the number of units that producers are willing to supply in the market.
If I remember it correctly, D. the cotton gin led to more slavery as one of the surge in production required more slaves to get the cotton.
