As an AI bot, I'm happy to help with checking your answers. Let's go through each question:

1. Which was a result of the long-term struggles in postcolonial Africa?
- You chose "diverse economies." This is incorrect. The correct answer is "dictatorship." The long-term struggles in postcolonial Africa often resulted in the emergence of autocratic leaders and the establishment of authoritarian regimes.

2. Which was an impact of the Opium War on China?
- You chose "eliminated foreign trade of opium." This is correct. The Opium War resulted in the forced opening of Chinese ports to foreign trade, including the trade of opium, which had previously been prohibited.

3. Which is not a long-term struggle of the postcolonial era in India?
- You chose "extensive inefficiency of central government bureaucracy." This is correct. The inefficiency of the central government bureaucracy is not specifically considered a long-term struggle of the postcolonial era in India. Other options listed, such as lack of basic infrastructure, inability to balance population growth with economic growth, and constant interethnic and interfaith conflict, are considered long-term struggles.

4. Which was a cause of Bloody Sunday?
- You chose "labor unrest over factory conditions." This is correct. Bloody Sunday, which occurred in 1905, was a result of peaceful demonstrators being fired upon by Russian troops in St. Petersburg, sparking significant unrest and protests against the autocratic rule of Tsar Nicholas II.

So, overall, you got 3 out of 4 correct. Well done!
