c. The Nile gave the Egyptians more access to trade.
d. The Nile deposited fertile soil.
Step-by-step explanation:
The silt is sediment transported in suspension by the rivers and by the wind, which is deposited in the bed of the water courses or on the lands that have been flooded. The silt deposited by the Nile River is typical after periodic flooding that provided fertile land for agriculture, from ancient Egypt. The Nile, when it overflowed every year, made its banks extremely fertile. It was thanks to that that the Egyptians were able to grow wheat, barley, and flax, in addition to providing the river with abundant fish and papyrus. All this made it possible to obtain enough food for the entire population and other important resources, which in general avoided possible famines, very frequent in the Middle East due to the irregularity of the crops. Thanks to the obtaining of flax and wheat made possible by the Nile and its floods, Egypt had a good diplomatic relations with other countries, with which the river contributed to the economic and political stability of the country, in addition, it provided the necessary resources such as food, water, or the money to own an army.
