To determine the best definition of a formal region, we need to analyze the given options and understand their meanings. Here's an explanation of each option:

1. A region defined by a uniting purpose, process, or function, including educational, economic, or civic purposes: This definition suggests that a formal region is characterized by a common objective or purpose, such as a specific educational system, economic activities, or civic initiatives. This definition emphasizes the functional aspects of a region.

2. A region with a clear political or physical boundary or set of shared characteristics: This definition focuses on the presence of a well-defined boundary, either political or physical, or a set of shared characteristics that distinguish the region. It emphasizes the tangible aspects that differentiate a formal region from surrounding areas.

3. A contiguous area on Earth’s surface, with either a formal or loosely defined boundary, characterized by one or more similarities that make it distinct from other areas: This definition highlights the physical contiguity of a region, which means it is a continuous area on the Earth's surface. It could have either a formal (officially recognized) or loosely defined boundary, but it must possess one or more similarities that set it apart from neighboring areas.

4. A region defined by how it is perceived by people, either by those within the region or by outsiders: This definition suggests that a formal region is determined based on people's perceptions, either from individuals living within the region or from people outside the region. It emphasizes the subjective aspect of defining a formal region.

This definition emphasizes the presence of distinct boundaries or shared characteristics that define a formal region.
