An advantage of the Harris and Ullman multiple nuclei model over the Burgess concentric zone model and the Hoyt sector model of internal city structure is that the multiple nuclei model
a) easily incorporates a depiction of linear and areal physical relief features
b) allows for the central business district to be situated in an edge city
c) is also applicable to rural areas beyond the urban periphery
d) easily incorporates the construction of a new airport on the urban periphery
e) has a monocentric focus that limits the inclusion of urban sprawl
