Answer:
Mongol leader Genghis Khan (1162-1227) rose from humble beginnings to establish the largest land empire in history. After uniting the nomadic tribes of the Mongolian plateau, he conquered huge chunks of central Asia and China. His descendants expanded the empire even further, advancing to such far-off places as Poland, Vietnam, Syria and Korea. At their peak, the Mongols controlled between 11 and 12 million contiguous square miles, an area about the size of Africa. Many people were slaughtered in the course of Genghis Khan’s invasions, but he also granted religious freedom to his subjects, abolished torture, encouraged trade and created the first international postal system. Genghis Khan died in 1227 during a military campaign against the Chinese kingdom of Xi Xia. His final resting place remains unknown.
Genghis Khan: The Early Years
Temujin, later Genghis Khan, was born around 1162 near the border between modern Mongolia and Siberia. Legend holds that he came into the world clutching a blood clot in his right hand. His mother had been kidnapped by his father and forced into marriage. At that time, dozens of nomadic tribes on the central Asian steppe were constantly fighting and stealing from each other, and life for Temujin was violent and unpredictable. Before he turned 10, his father was poisoned to death by an enemy clan. Temujin’s own clan then deserted him, his mother and his six siblings in order to avoid having to feed them.

Answer: B.the vassal’s promise to provide service to the lord
Feudalism was a social system that was dominant in medieval Europe, between the 9th and 15th centuries. It was a way of structuring societies so that the nobility held lands from the Crown, in exchange for military service. In turn, vassals were tenants of the nobles. The serfs (peasants) lived on their lord’s land in exchange for labor, service and a share of produce. In exchange, the lord promised to provide military protection to the serfs.
Responsibilities were based around the ideas of protection and service. Because of a vassal’s commitment to provide service for his lord, large armies could be easily gathered. This fulfilled the promise towards the lord (and ultimately the Crown), and also provide the military protection that serfs were owed.
