Response:
There will be an increase in equilibrium quantity, but the impact on equilibrium price remains uncertain.
Note:
Due to the scientists' discovery, demand for oranges will rise, as will the price.
Additionally, the introduction of new fertilizers will boost the supply of oranges, leading to a price decrease.
Taking both of these factors into account indicates that there will be a rise in equilibrium quantity, while the effect on equilibrium price cannot be determined.
