Answer:
1. How did the plague reshape European Society?
The plague (the Black Death) killed over a third of the European population at the time, although it did not strike all European regions with the same intensity.
This amount of death meant that now there were fewer workers to farm the same amount of land as before. This created a shortage of workers which raised wages, and at the same time, reduced the rents that landowners obtained from their territorial possessions.
2. What were the causes, course, and consequences of the Hundred Year War?
The causes were dynastic conflict between the Kingdom of France and the Kingdom of England. The English king claimed the throne of France.
At first, the war was favorable for England, obtaining many victories against the French Calvary with the famous English archers. In the latter stages of the war however, the French army began to obtain victories and regained territory.
The consequences was the decline of the Calvary as the main battle force in war. Another consequence was that the English Kings never again claimed the French throne.
