Answer
These two events that will lead to both increase supply and increase demand.
This will result in both the supply curve and the demand curve shifting to the rightward.
However, we don't know how much either curve will shift, this will result in a new equilibrium price that is similar to the previous equilibrium price.
Work Step by Step
As per the new finding by the scientist, we get to know that the consumption of oranges decreases the risk of diabetes.
So, as a result, the demand for oranges increases at each price level.
Graphically, we get to know that the demand curve will shift rightward.
Whereas, The farmer uses new fertilizers which makes oranges more productive.
As a result, there will be more oranges which ultimately leads to an increase in supply at each price level.
Graphically, we get to know that the demand curve will shift rightward.
