Answer:
They moved west.
Step-by-step explanation:
It is TRUE that the Iroquois MOVED WEST when the beaver population declined in the middle of the seventeenth century.
Initially, the Iroquois hunted for Beaver as a major source for fur production, which they trade with the European settlers. However, following the decline of the animal in the area of present-day New York, the Iroquois moved westward to hunt for more Beavers in the area of Ohio county.
