What significant event did the Liberty Bell mark?

The correct answer highlights that the Liberty Bell is historically associated with the signing of the Declaration of Independence. This event, which took place on July 4, 1776, symbolized the American colonies' formal assertion of independence from British rule. The bell, originally cast in 1752, has since become an enduring symbol of freedom and the quest for liberty in America.

The significance of the Liberty Bell transcends its physical presence; it represents the ideals of liberty and justice that were pivotal during the founding of the nation. The bell is famously inscribed with the message "Proclaim LIBERTY Throughout all the Land unto all the Inhabitants thereof Lev. XXV. v X," which reinforces its association with freedom.

While the other options refer to important historical events, they are not directly linked to the Liberty Bell's legacy. The Bill of Rights, the end of the Civil War, and the start of the American Revolution all hold their own significance in American history, but none of these events share the same iconic connection with the Liberty Bell as the signing of the Declaration of Independence does.
