A best answer

Actually, the correct answer for the definition of a formal region is a) has boundaries determined by a common characteristic.

A formal region, also known as a uniform or homogeneous region, is an area that is defined by a common characteristic or set of characteristics that are present throughout the region. This common characteristic could be anything such as language, religion, climate, economic activity, or political system.

So, while it is true that different types of transportation systems can exist within a formal region, the defining characteristic of a formal region is not its transportation system, but rather the common characteristic or feature that determines its boundaries.

To explain how we arrived at this answer, we can look at the options provided:

a) has boundaries determined by a common characteristic - This is the correct answer because a formal region is defined by a common characteristic that helps establish its boundaries.

b) includes people who speak a variety of languages - This describes a region with linguistic diversity, but it does not specifically define a formal region.

c) has different types of transportation system - While transportation systems can vary within a region, this does not define the concept of a formal region.

d) includes both rural and urban populations - This describes a region with a mix of rural and urban areas, but it does not specifically define a formal region.

By considering the characteristics of a formal region and analyzing the provided options, we can determine that the correct answer is a) has boundaries determined by a common characteristic.
