Explanation:

The New England Colonies consisted of Connecticut, Rhode Island, and Massachusetts. Those territories provided fish, lumber, and fur. On the other hand, the Middle Colonies  produced corn and wheat while the Southern Colonies focused on rice, indigo, tobacco, and later, cotton. Because of this, the Southern Colonies had a higher rate of slavery.

The New England Colonies were primaraly settled by Pilgrims and Puritans, while the Middle Colonies were more diverse in population which led to more tolerance in them.
