Final answer:
The increased duties led to colonial resentment against the British, ultimately contributing to increased warfare and rebellion, paving the way for the American Revolution.
Step-by-step explanation:
The increase in duties as described in the passage directly contributed to an increase in warfare and rebellion in the Americas. This was due to British attempts to impose new taxes on the colonists and more vigorously enforce the collection of existing ones to pay off massive debts from the French and Indian War and maintain British troops in North America. These actions led to colonial resentment, restrictions on the colonial paper currency, the sense of violated rights, and ultimately to the American Revolution.
