US History: Chapter 1, Exercise 2 — Possible Solution
======================================================================

QUALIFICATION
The article says the land has tens of thousands of years of continuous
Indigenous societies (settlement perhaps as early as 30,000 years ago), and its
own periodisation starts with an Indigenous period. It also says 1607, Jamestown,
is when the history of the present-day United States began, which answers a
different question: when the state's history began.

REWRITE
"The state's history is often dated from the English settlement of 1607, but
people lived here for tens of thousands of years before that."
