How did european imperialism following the industrial revolution differ from earlier forms of imperialism?

a. it was based on military power rather than economic power.
b. it was less widespread and more focused on dominating small areas.
c. it was used in africa and asia rather than only the americas.
d. it was less concerned with conquering and governing territories.

Which of these is not a criticism of the concentric zone model? it does not accurately describe cities after the rise of suburban development. it only applies to cities that grew after the development of the automobile. it assumes that inner-city areas will always be repurposed instead of abandoned. it places too much importance on the traditional central business district.
