Final answer:
Egyptian farmers along the Nile River were more fortunate than those in Mesopotamia because the Nile had predictable flooding patterns, which facilitated the development of a harmonious society and an organized agricultural system.
Step-by-step explanation:
The farmers who were more fortunate because of the predictable flooding belonged to the region along the Nile River in ancient Egypt. Unlike the Tigris and Euphrates rivers in Mesopotamia, which caused unpredictable flooding creating various challenges for farmers who had to work extensively on hydrological systems such as levees, canals, the Nile's flooding was regular and reliable. This predictability led to a harmonious and organized way of life in Egypt, including the development of complex irrigation systems and agriculture that was heavily dependent on the annual silt deposits from the seasonal floods.
