Which document was the first step in determining how to establish a government that would unite the
colonies?
a) conservative confederation
b) the federalist papers
c) annapolis constitution
d) albany plan

D) Albany Plan

Explanation:

The Albany Plan was a failed attempt to unit the colonies.

I'm unsure as of what A is so I crossed that out + I've never heard of it in U.S History so that's out.

B is a series of essays to convice people as to why they need to be in support of the constitution which is also out.

C. The Annapolis Convention was basically a meeting to discuss the Articles of Confederation so I eliminated this answer too.
