Question

a. the boxer rebellion
b. the russo - japanese war
c. the opium wars
d. the sepoy rebellion

1. the u.s. \open door policy\ was meant to:

a. divide africa among european powers
b. keep trade in china open to all nations
c. prevent immigration to the united states

Explanation:

For question 4:

• The Boxer Rebellion was a later anti - foreign movement in China (1899 - 1901) not directly caused by opium trade.
• The Russo - Japanese War (1904 - 1905) was between Russia and Japan over territorial disputes in East Asia, not related to British opium trade to China.
• The Sepoy Rebellion (1857 - 1858) was in India against British rule, not related to China - Britain opium trade.
• The Opium Wars (First Opium War 1839 - 1842, Second Opium War 1856 - 1860) were directly caused by British opium trade to China and China's attempts to stop it.

For question 5:

• The "Open Door Policy" (1899 - 1900) was about China. It was proposed by the U.S. to ensure that all countries had equal access to trade in China, not about dividing Africa (which was more related to the Berlin Conference for Africa's partition among European powers).
• It was not about preventing immigration to the U.S. (which had its own immigration acts like the Chinese Exclusion Act etc., but that's a different issue).

Answer:

1. C. The Opium Wars
2. B. Keep trade in China open to all nations
