Answer :
The political boundaries in Europe in 1914 and 1919 represent a formal region.
Formal regions are defined by a common characteristic or attribute, often a government-imposed boundary. In this case, the political boundaries are determined by national governments and treaties, making them a formal region.
Transitional regions are areas where characteristics change gradually, often due to cultural or environmental factors. Functional regions are defined by their function or purpose, such as economic or transportation networks. Perceptual regions are defined by people's perceptions and subjective beliefs.
