Answer:
B)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.
Step-by-step explanation:
The development of civilizations on both China and Mesoamerica was in big part because of the fertile soil that they both had, the maoin difference between the two of them was that the Yellow river in China was a steady, reliable source of water all year long, this allowed them to farm and grow crops all year long, on the other hand in Mesoamerica the rivers didn´t have the strength and weren´t as relieble as the Yellow river in China, this meant that the agriculture relied on rainwater to grow crops.
