Final answer:
Peasants moved to cities for better employment opportunities and favorable labor terms, while nobles moved to cities to maintain status and take advantage of trade and economic opportunities.
Step-by-step explanation:
At the end of the Middle Ages, both peasants and nobles moved to cities for various reasons. Peasants moved to cities to seek better wage labor and employment opportunities because the plague had caused labor shortages in the countryside. They also moved to cities because landlords in urban areas offered more favorable terms of labor. Nobles, on the other hand, moved to cities to maintain their social and economic status and to take advantage of the growing trade and economic opportunities in urban areas.
