Explanation:

The information given here is all related to the location of Paraguay. While the country is in the Latin American region, it is also part of other regions such as South America, the Gran Chaco, or Mercosur.

The description is not of movement because countries do not move. Nor is the description about human-environmental interaction since we only know about Paraguay's borders.

Location is the answer because we can locate Paraguay on a map between these larger countries.
