Final answer:
The manors came under the control of the aristocracy as the Roman Empire began to break down, leading to a decline in the average person's quality of life.
Step-by-step explanation:
As the Roman Empire began to break down, there was a shift in the manorial system. The manors, which were large estates with enslaved people working the land, came under the control of the aristocracy. The economy shifted back to a more manorial system, where the noble overlords gained more control over the land and the peasants became more dependent on them. This led to a decline in the average person's quality of life as they were subjected to the control and demands of the noble overlords.
