The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The name of this document was the Mayflower Compact.
It is true that the Pilgrims laid the foundation for representative government in America when they landed at Plymouth in 1620 and wrote a document that contained the idea that the power to govern should come from the consent of the people. That document was the Mayflower Compact.
The document was written when the Pilgrims were traveling on the Mayflower ship that took them to Cape Cod, Massachusetts. This agreement resulted in the first consensual document to establish a type of government that served to establish order and harmony in that Pilgrim colony.
The Pilgrims arrived at Cape Cod on November 11, 1620.
