Answer: He compares the colonies to pieces of a snake because he believes the colonies will be ineffective unless they work together.
Step-by-step explanation:
During the French and Indian War, Benjamin Franklin published through his newspaper, a picture titled ''Join or Die''. It was a call to colonial unity between the colonies in the fight against the French and their Indian allies.
He represented the colonies as parts of the same snake to show that they all needed each other to survive because a snake that is missing parts cannot very much hope to survive.
