It is clear that a critical assumption behind the concentric zone model of a city is that it has an isotropic surface,meaning that the model city
A) is flat, uniform and barrier free.
B) does not have motorized transportation.
C) only has streets that are parallel and perpendicular to each other.
D) has high buildings in the center which get lower with distance outward.
E) is located on a slope, like a mountain side.

The isotropic surface assumption implies that the surface of the city is flat and uniform, without barriers or obstacles that would affect the spatial distribution of activities and people. This is a crucial assumption for the concentric zone model, which posits that different social groups and land uses are arranged in a series of concentric rings around the central business district. If the surface of the city were not isotropic, such as if there were a river, a mountain, or a steep slope, this would disrupt the logic of the model and require additional modifications or alternative models. Choices B, C, D, and E are all irrelevant or inaccurate with respect to the isotropic surface assumption.
