Final answer:
Scottish immigrants helped develop North Carolina's economy in the 1720s by contributing to its maritime goods production and tobacco trade despite geographical challenges.
Step-by-step explanation:
Based on the two maps and historical context given, we can infer that Scottish immigrants played a significant role in the development of North Carolina. In the Carolina colony, divided into North and South Carolina in the 1720s, Scottish settlers in North Carolina contributed to its economic growth with the production of goods essential for maritime activities, such as turpentine and tar. Despite the geographical challenges of marshlands and a lack of natural harbors, the increase in the population due to Virginians and likely Scots moving in helped the colony flourish, especially in its trade of tobacco, the primary export, as well as deerskins and enslaved Africans.
