Answer:
The answer is D. Obesity.
Explanation:
A serf is a worker bound to a certain piece of land (called a fief) who is loyal to a vassal (lord or noble) above him, usually called a lord. Serfs are tied to the land they work, perform the same menial tasks each day, and receive little or no benefit for their labors. Serfs were part of the feudal system that existed in the European Dark Ages, ca 500-1450 CE.
In the feudal system, serfs were at the bottom of the social order. As feudalism follows a hierarchical form, there were more serfs than any other role. Above serfs were peasants, who shared similar responsibilities and reported to the vassal. The main difference between serf and peasant is that peasants were free to move from fief to fief or manor to manor to look for work. On the other hand, serfs were like slaves, except that they could not be bought or sold.
The life of a serf was very difficult. Their clothes were ragged, houses were of extremely poor quality, and food was scarce. Each day for a serf was spent working hard on the land they were bound to. They did not receive this land for free because they had to pay taxes called tallage to the lord of the land. This tax was either actual money or, more commonly, by providing services to the lord. An additional aspect of the tallage consisted of giving part of their sowed crops to the manor.
