Correct answer:
D. the ownership by individuals of small farms.
The monastic communities have monastic centers in several places like Ethiopia, Georgia, Greece, Republic of Macedonia and Russia. Although the monks lived in huts or individual rooms during the Middle Ages, the shared spaces served as an innovation in the use of land. The open field system was the agricultural system that prevailed in much of Europe during the Middle Ages and innovated the use of acres of land. The system of three fields in medieval Europe was also implemented, which innovated the use of the land by being able to cultivate different types of crops in the same area in sequential seasons.
