Scenarios will be shown here.
Expansion of supply
Left shift of supply
Right shift of supply
In the area above you will be presented with scenarios. You need to choose whether the scenario will cause a contraction of supply, an expansion of supply, or a left or right shift of the supply curve.
Contractions and expansions of supply both happen because of a change in price of the product in question.
Shifts of the supply curve happen for a variety of other reasons such as changes in the population, the effects of government policies and many more.
