Answer
The equilibrium quantity will increase. However, the equilibrium price may not increase.
Work Step by Step
Please see the graph. The original equilibrium is marked E.
There will be an increase in demand for oranges due to a decreased risk of diabetes. The shift (to the right) in the demand curve is in green.
There will be an increase in supply due to the technological improvements (the fertilizer producing more oranges). The shift in the supply curve will be to the right and in orange.
The equilibrium quantity will increase. However, the equilibrium price may not increase.
