The map shows a railway to Washington that was built in the 1800s. Which STATE was the point of origin (starting point) of this railroad line?

 Shay's rebellion was important to highlight the problems with the Articles of Confederation because it showed the people and government how terrible the Articles couldn't handle a crisis.

I hope this helps.
