A. They constructed the Aswan Dam to eliminate seasonal flooding

Explanation:

In order to prevent the Nile River to cause damage to the ancient architecture and the cities located on its shores, the Egyptian government decided to create a dam, the Aswan Dam. Another reason for the creation of this dam was to produce hydroelectricity. While this prevented the damages that the annual floods caused, it also created lot of problems in the agricultural sector. Because the floods have been stopped, the river stopped to fertilize the soil in its valley with large amounts of fertile deposits. This has resulted in higher costs for the farmers because they had to start using artificial fertilizer in order to have the same amount of crops. The fertilizers though cause damage on the soil, as they make it easier to erode, so more and more fertilizers have been used. Apart from this, Egypt lost a lot because its food has become much more contaminated with chemicals, and its quality has lowered significantly.
