The answer is: Some people rose up against the government because they were unhappy with high taxes and other problems.
While conflicts with the Mongols were a significant issue during the Ming Dynasty, the primary reasons for rebellion were more related to internal issues rather than external military campaigns.
The shift to a silver-based economy did cause economic disruptions and dissatisfaction, but it was not the primary reason for widespread rebellion. The economic changes did contribute to social unrest, but they were part of a broader set of grievances.
This option is the most accurate. High taxes, corruption, and mismanagement were significant factors that led to widespread discontent and rebellion. The Ming Dynasty faced numerous internal challenges, including natural disasters, famine, and economic hardship, which were exacerbated by heavy taxation and corrupt officials.
While there were debates about foreign trade policies, this was not a primary cause of rebellion. The Ming Dynasty's trade policies were complex, and while some factions opposed certain aspects of trade, it was not a central issue for most rebellions.
