Question

Why does Egypt care if a country south of them is building a dam?

The river flows south, so it could back up trade
Egypt always worries about anything to do with the Nile
The river flows north, so it could lower their water level.
They do not really care; they just think it is not needed.

Answer 1

C

Step-by-step explanation:

The Nile river actually flows south to north, so if a country south of them, lets just say Sudan hypothetically, were to build a dam, then the rest of the river that passes through Egypt would have much lower water levels than the one south of the dam. Egypt is heavily reliant on the Nile for many reasons, and lower water levels could be catastrophic.
