Final answer:
b. Paragraph 31 explains why the colonists decide to go to war with the British.
Step-by-step explanation:
The author included paragraph 31 to b. explain why the colonists have decided to go to war with the British. The paragraph states that the colonists did not get the response they were hoping for from the British government. The British government declared Massachusetts in rebellion and imposed restrictions on trade with other countries.
The British's unsatisfactory response and aggressive actions at Lexington and Concord led to the colonists' decision to declare independence.
