What is most likely to be a significant part of the middle colonies economy in 17th century North America?

The economy of the middle colonies in 17th century North America was significantly characterized by a mix of agriculture and trade. These colonies, including New York, New Jersey, Pennsylvania, and Delaware, benefited from fertile land that facilitated the cultivation of grains such as wheat, barley, and oats, earning them the nickname "the Breadbasket." Additionally, their strategic location along major rivers and coastal trade routes enabled robust commercial activities, including the export of agricultural products and import of goods. This diverse economic foundation contributed to a relatively prosperous and dynamic region during that period.
