Final answer:
The problems faced by the Third Estate in France, including poverty, hunger, and heavy taxation, were a major cause of the French Revolution in 1789.
Step-by-step explanation:
The problems faced by the Third Estate in France were a major cause of the French Revolution. The Third Estate, consisting of the majority of the population including peasants, urban workers, and the middle class, was burdened with heavy taxation while the aristocracy enjoyed tax exemptions. Additionally, poverty and hunger were widespread among the Third Estate, exacerbated by failed crop harvests. This economic inequality and suffering fueled discontent and resentment, eventually leading to the outbreak of the French Revolution in 1789.
