Short Answer

\(e) \text{ will fall}\)

Step by step solution

01

Understanding the relationship between demand, supply, and equilibrium quantity

Equilibrium quantity is the quantity at which the quantity demanded equals the quantity supplied. It occurs at the intersection of the supply and demand curves. When there is a change in either demand or supply or both, the equilibrium quantity can change.
02

Analyzing the situation when both demand and supply fall

In this case, demand and supply both fall. When demand decreases, this means that consumers want to purchase less of the good at any given price, so the demand curve shifts to the left. On the other hand, when supply decreases, it means that producers are willing to sell less of the good at any given price, thus the supply curve shifts to the left as well.
03

Understanding how changes in demand and supply affect equilibrium quantity

Both demand and supply shifting to the left means that the intersection point of the demand curve and the supply curve (the equilibrium point) will move down and to the left. Since we are only concerned about the equilibrium quantity, we can focus on the horizontal axis of the intersection point. As the intersection point moves to the left along the horizontal axis, the equilibrium quantity decreases.
04

Selecting the correct answer

The equilibrium quantity decreases in this scenario. So, the correct answer should represent a decrease in the equilibrium quantity. Based on the given choices, the correct answer is: e) will fall
