Question

the second aswan dam, which was completed in 1970, was built to prevent the nile river from flooding, generate electricity, and store water for agricultural uses. while the damming of the nile has generated electricity and stored water as originally intended, the project has also created new cultural and environmental problems.
erosion of the coastline, pollution in the nile from the use of chemical fertilizers, and an increase in the salt present in the mediterranean are a few of the environmental problems caused by the dam. in addition, 60,000 people were displaced from their homes when nubia, located in southern egypt, was flooded, and important cultural sites have been destroyed by the dams presence. therefore, it remains to be seen whether the aswan dam has solved as many problems as it has caused.

○a. the erosion of the coastline
○b. increased salt in the mediterranean
○c. the destruction of cultural sites

Explanation:

The text states that when the second Aswan Dam was built, Nubia (located in southern Egypt) was flooded. Options A and B are environmental problems caused by the dam but not the cause of Nubia's flooding. Option C is a result of the dam (flooding led to cultural sites' destruction), not the cause of flooding. Only option D (the building of the second Aswan Dam) is directly stated as the reason for Nubia's flooding.

Answer:

D. the building of the second Aswan Dam
