Question

how did the boston massacre impact the colonies? it made britain repeal its new taxes. it quashed the rebellion in boston. it rallied colonists against british rule.

Explanation:

The Boston Massacre (1770) involved British soldiers killing colonial civilians, which was sensationalized by figures like Paul Revere through propaganda. This event unified colonists, fostering anti-British sentiment and strengthening calls for resistance, laying groundwork for the American Revolution. The other options are incorrect: Britain did not repeal new taxes immediately (the Tea Act followed later), and it did not quash rebellion—instead, it escalated colonial unrest.

Answer:

It rallied colonists against British rule.
