The correct answer is D. Barbed wire allowed farmers to enclose their lands.
Explanation
The great plains are a region of the United States in which different economic activities have been carried out, among which agriculture and cattle raising stand out. However, this relationship was mediated by the disagreement felt by ranchers towards farmers who increasingly covered more areas of this region. For this reason, ranchers broke into the land of farmers and damaged their crops or attacked against farmers lives, for this reason, one of the farmers, tired of this situation, took as inspiration the use that was given to some bushes with thorns that were used as a barrier to prevent entry to private land and created barbed wire to prevent ranchers from entering farmers' land. With this invention, farmers began to fence off their land and limited the enter of ranchers who infiltrated to attack the crops and their owners. According to the above, the correct answer is D. Barbed wire allowed farmers to enclose their lands.
