US History: Chapter 4, Exercise 1 — Possible Solution
======================================================================

WHAT WAS TRANSFERRED
The chapter says scholars emphasise the US primarily acquired "the preemptive
right to obtain Indian lands by treaty or by conquest," with subsequent
settlements costing about $2.6 billion through 2012.

WHY INCOMPLETE
"Bought the land" implies clear possession changing hands between two
governments, but the land was inhabited and France's own claim to it was
itself contested. The purchase transferred a claim against other European
powers, not full control of the territory.
