Final answer:
The fact that peasants could escape poverty and serfdom after the Plague led to improved living conditions, higher wages, and the gradual end of serfdom in Western Europe.
Step-by-step explanation:
The fact that peasants could now escape poverty and serfdom meant that their living conditions improved after the Plague. With fewer people, the surviving peasants had access to more lands and resources. They also had the opportunity to earn better wages and living conditions by settling on the lands of nobles who needed workers. This led to a rise in peasant wages and the gradual disappearance of serfdom in Western Europe.
