Final answer:
The fate of cities during periods of increased economic production was influenced by a variety of factors including invasions, diseases, agricultural productivity, transportation, commerce, climate changes, and the rise and fall of older versus newer cities.
Step-by-step explanation:
The varied fates of cities in the context of increased economic production can be attributed to several factors. Option A suggests that the decline of some cities was due to invasions, diseases, and a decline in agricultural productivity, which relates to broader historical patterns of urbanization and de-urbanization over time. Option B points to urban revival due to the end of invasions, safe and reliable transportation, the rise of commerce, and warmer temperatures, particularly in the Medieval Warm Period between 800 and 1300.
Option C cites that older cities declined while new cities arose to fulfill traditional urban roles and functions. Option D, which states 'All of the above,' is the correct choice as it encompasses the reasons and patterns behind the varying fortunes of cities throughout history, including during periods of industrialization when technological advancements and socioeconomic changes dramatically reshaped urban landscapes.
