Why did the US have to go into War in World War 1? Was there national interest at stake? Was it pride, moral or something else? Why then did the US opt to expand its treasure and the lives of its citizens in this way?

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.
