Final answer:
New England's development was shaped by its extensive coastline, which facilitated trade and shipbuilding. The region's rocky soil and long winters limited large-scale agriculture, leading to a focus on maritime activities.
Step-by-step explanation:
The New England region's development was most directly influenced by its geographic features, particularly its extensive coastline. This is reflected in the region's historical engagement in whaling and fishing for export and its leadership in the shipbuilding industry.
The coastline provided natural harbors, which were beneficial for trade and naval construction. The rocky soil and long winters made large-scale agriculture difficult; thus, most farmers grew for self-sufficiency. New England's development was therefore shaped by its ability to engage in maritime activities rather than by fostering large-scale agriculture or industries such as the cotton industry.
