Which of the following was a significant event during the American Revolution?

The Boston Tea Party was indeed a significant event during the American Revolution because it acted as a catalyst for colonial unrest against British rule. Taking place on December 16, 1773, colonists, frustrated by British taxation without representation, took decisive action by dumping 342 chests of British tea into Boston Harbor. This act of defiance not only demonstrated the growing tensions between the colonies and the British government but also united the colonies in resistance against British policies. The event directly led to the implementation of the Intolerable Acts by the British Parliament, further escalating the situation and galvanizing the colonies to pursue independence.

In contrast, the signing of the Constitution occurred after the American Revolution, marking the establishment of the federal government. The Civil War was a conflict that took place decades later, over issues primarily related to slavery and states' rights, while the Industrial Revolution refers to an era of industrial growth and technological advancement that happened in the 18th and 19th centuries, also well after the American Revolution.
