[单项选择] Surprisingly enough, modern historians have rarely interested themselves in the history of the American South in the period before the South began to become self-consciously and distinctively "Southern" -- the decades after 1815.

A. The Southern colonies shared a common culture.

D. There were significant differences between Puritan and Southern culture during the Colonial period.
