Answer:
The "fence" problem; cattle would trample over and destroy the crops.
Explanation:
The Great Plains are broad flat lands that the settlers had to build their soddy homes from. They also had to dig up water wells in which they would haul water from. Many problems in the plains were overcome by technology. One problem was the "fence" problem because cattle would trample over and destroy the crops. However, that was easily fixed when "barbed wire" was invented.
