Final answer:
According to Central Place Theory, all the mentioned statements are true (d), as cities demonstrate economies of scale, with centralized economic activities leading to higher efficiency. Cities also exhibit a geometric pattern of development due to more centrally located places growing at the expense of peripheral ones.
Step-by-step explanation:
According to the Central Place Theory, the statements that cities are able to produce goods and services more efficiently than smaller places (a), cities promote competition among producers (b), and economic advantages increase as one moves closer to the central business district (c), are all true. Therefore, the answer is (d) all of the above are true. The theory explains why economic activity and population tend to be centralized in cities, highlighting the concept of economies of scale, which describe the efficiency gains from concentrating activities.
In cities, businesses can access a large pool of customers, workers, and specialized suppliers, which enables them to operate more efficiently. This leads to lower average costs and increased production capacity. Moreover, cities can support a variety of higher-order goods and services which cannot be found in smaller towns or rural areas.
The geometric pattern of towns and cities emerging in flatland regions like Kansas during the 1800s exemplifies Central Place Theory in practice. More centrally located villages tended to attract more businesses and customers, growing into larger towns or cities, while less conveniently located villages did not grow significantly. This phenomenon was especially pronounced when transport was less developed and the friction of distance was a greater obstacle.
However, despite the advantages of cities as centers of economic activity, there are limits to these benefits. Agglomeration economies can turn into diseconomies when factors like traffic congestion, pollution, and overcrowding offset the advantages of dense, centralized populations. This balancing act explains why not everyone chooses to live in one enormous city.
