a region with a clear political or physical boundary or set of shared characteristics

The best definition of a formal region is a region with a clear political or physical boundary or set of shared characteristics. To arrive at this answer, we can eliminate the other options by examining their descriptions.

The second option is a repeat of the first option, so we can disregard it.

The third option describes a contiguous area on Earth's surface, which may have either a formal or loosely defined boundary. It is characterized by one or more similarities that make it distinct from other areas. This sounds more like the definition of a functional region, which is defined by its purpose or function, such as an economic or educational region.

The fourth option is identical to the third option, so we can disregard it.

The fifth option describes a region defined by how it is perceived by people, either by those within the region or by outsiders. This definition aligns with a perceptual region, where a region is defined by subjective feelings and opinions rather than concrete boundaries or characteristics.

Therefore, based on the descriptions given, the best definition of a formal region is the first option: a region with a clear political or physical boundary or set of shared characteristics.

The best definition of a formal region is: a region with a clear political or physical boundary or set of shared characteristics.
