The response that best distinguishes the key causes of the American, French, and Haitian Revolutions is:
The American colonists wanted to control their own government; the French people were starving with no relief from the king; the Haitian people wanted freedom from slavery.
This response accurately reflects the primary motivations for each revolution: the American colonists sought self-governance, the French faced economic hardship and wanted political reform, and the Haitian people fought for freedom from slavery.
