Answer:
Trough.
Step-by-step explanation:
In the Business Cycle, the trough phase happens after the contraction and before the expansion. That point of the cycle marks the end of the decline that starts in the Contraction phase after the Peak.
The Federal Reserve takes action at this point of the business cycle to stop it and move towards the Expansion phase that is when employment levels, business activity, and gross domestic product resurge.
