Answer:
Mercantilism
Explanation:
The breadbasket colonies exporting goods exclusively to England is an example of "mercantilism".
From the 16th -18th century, mercantilism was known to be an economic system of trade. It was based on the fact that if the nation's wealth and power can be well served, then there must be increase in exports. This exports involved the increase in trade.
Those in support of mercantilism (the Mercantilists) believe that in order to assess the nation's economic status, the levels of ownership of gold, silver, etc should be looked into.
The breadbasket colonies are the middle colonies. They had hills and rich, fertile soil and as a result, the people who settled here established many small farms.
