Final answer:
The Nile was crucial for Egypt, providing sustenance through grains and fruits, watering cattle, and preserving life, but it did not cause suffering.
The correct option is d.
Step-by-step explanation:
The Nile was vital for Egypt for several reasons but not for causing suffering. It provided grains and fruits, watered the cattle, and sustained the lives of people and animals.
Unlike the unpredictable flooding of the Tigris and Euphrates which brought destruction along with fertility, the predictable, annual inundation of the Nile was characterized by bountiful harvests and not by suffering.
The Nile's significance for Egypt lies in its positive impacts, including the provision of essential resources like grains and fruits, support for livestock through watering, and sustaining life for both humans and animals.
The passage does not attribute any negative aspect, such as causing suffering, to the Nile's role in Egypt.
The correct option is d.
