Answer:
1.) The Boston Massacre was a confrontation on March 5, 1770, in which British soldiers shot and killed several people while being harassed by a mob in Boston. The event was heavily publicized by leading Patriots such as Paul Revere and Samuel Adams.
2.) The phrase comes from the opening stanza of Ralph Waldo Emerson's "Concord Hymn" (1837) and refers to the first shot of the American Revolution at the Old North Bridge in Concord, Massachusetts, where the first British soldiers fell in the battles of Lexington and Concord on April 19, 1775.
3.) If the patriots had lost the Revolutionary war, the Americans would still be under British control and have to deal with the treatment they dealt with before such as paying taxes from over seas and having to house soldiers in their homes. You could also say that if they lost the war, they would probably be horribly punished for their actions in trying to separate from Great Britain. I don't know if treason is the correct word, but they could maybe see it as that.
Hope this helps!
