Question

the revolutionary war started with which of these events?
the battles of lexington and concord
the siege of yorktown
the boston tea party
the approval of the declaration of independence

Explanation:

The Siege of Yorktown was a late, decisive battle that ended major combat in the Revolutionary War. The Boston Tea Party was a pre-war protest over taxation, not the start of open warfare. The Declaration of Independence was approved after the war had already begun. The Battles of Lexington and Concord in April 1775 were the first open military engagements between colonial militia and British troops, marking the start of the Revolutionary War.

Answer:

the Battles of Lexington and Concord
