Which of the following best contrasts the role that geography played in the development of civilizations in China and in Mesoamerica? A. China's Indus River contributed to the development of trading networks; the slow and swamplike rivers in Mesoamerica caused people to rely more on rainwater for farming. B. The slow and swamplike rivers in China caused people to rely more on rainwater for farming, Mesoamerica's Indus River contributed to the development of trading networks. C. China's Yellow River valley was fertile and ideal for farming; the slow and swamplike rivers in Mesoamerica caused people to rely more on rainwater for farming. D. The slow and swamplike rivers in China caused people to rely more on rainwater for farming; Mesoamerica's Yellow River valley was fertile and ideal for farming.

China's Yellow River, known as the "cradle of Chinese civilization," provided fertile soil due to annual flooding, which made it perfect for agriculture and led to the establishment of early dynasties. Meanwhile, in Mesoamerica, the geography was quite different; the region had a mix of swamps and mountains that often interfered with direct river access, resulting in communities developing sophisticated rainwater harvesting and irrigation systems to sustain their agriculture. In real-world applications, understanding these geographical differences helps historians and geographers analyze how civilizations adapted to their environments. For instance, the reliance on the Yellow River in China allowed for the growth of a centralized state early in history, while Mesoamerican societies like the Maya and Aztecs developed unique agricultural techniques, such as chinampas (floating gardens), to thrive despite environmental challenges.
