Question

to drive out foreign influences, the main thing the boxers did was to
recruit members openly.
oppose any kind of immigration.
force closure of all the ports in china.
kill foreigners, missionaries, and chinese christians.

Explanation:

The Boxer Rebellion (Yihetuan Movement) aimed to drive out foreign influences. The Boxers (Yihetuan) mainly targeted foreigners, missionaries, and Chinese Christians as part of their efforts to eliminate foreign presence and influence. Let's analyze the options:

• "recruit members openly" is incorrect as the Boxers' main action wasn't open recruitment for driving out foreign influences.
• "oppose any kind of immigration" is not accurate as their focus was on existing foreign influences and related people, not just immigration.
• "force closure of all the ports in China" is not a main action of the Boxers.
• "kill foreigners, missionaries, and Chinese Christians" aligns with their violent actions against those seen as representing foreign (especially Western and Christian) influence.

Answer:

D. kill foreigners, missionaries, and Chinese Christians.
