Final answer:
The Qing dynasty's inability to quell internal unrest was due to corruption, economic issues, and social inequality. These factors, exacerbated by natural disasters and nationalistic revolts, culminated in the dynasty's decline and eventual fall.
Step-by-step explanation:
The Qing dynasty's failure to deal with internal unrest can be attributed to a combination of factors, leading to the correct answer being (D) All of the above. First and foremost, corruption and inefficiency within the government hampered effective management and response to crises. The bureaucracy was plagued by officials who were more interested in their own gain rather than the welfare of the state. This led to widespread mismanagement of the treasury and fiscal resources, which were essential for maintaining social order and public projects.
Moreover, economic stagnation and poverty contributed greatly to the internal turmoil. As inflation and scarcity of food increased, peasants were faced with prices that were beyond their reach, leading to widespread discontent and ultimately to rebellions. Furthermore, widespread social inequality and injustice fueled anger and resentment among the populace, particularly against the ruling class. This was exacerbated by natural disasters like droughts, floods, and epidemics which the weakened Qing state was ill-equipped to handle effectively. Lastly, nationalism and factional politics played a significant role in the Qing Dynasty's struggles, leading to a loss of control over various parts of the empire.
