The correct answer is B) the yellow fever outbreak.
The cause of the jump in prices was the yellow fever outbreak.
We are talking about 1793 in the city of Philadelphia, Pennsylvania. This was a virus that provoked pain in joints and muscles, as well as fever. Then the virus affected the liver and the kidneys of the patient. Mosquitos were the transmissions of yellow fever. Refugees from the Philipines landed in Philadelphia and that is why they spread the virus in that region of the United States. This virus caused prices to go higher, affecting the economy of the region.
