Question

if scientists were to use the aswan low dam as an example of the effectiveness of a hydroelectric dam, what should they expect to happen to the aswan high dam in the future? they should expect that demand for the water will eventually ruin the dams effectiveness. they should expect that the architectural design will eventually break and crumble. they should expect that the local people will eventually demand that the dam be removed. they should expect that local pollution and over - fishing will eventually destroy the water supply.

Explanation:

Hydroelectric dams face challenges from water demand. The Aswan Low Dam's example implies water - related issues. Option A focuses on water demand affecting dam effectiveness, which is a key factor for hydroelectric dams. Options B (architectural design break - down) is less likely as dams are engineered structures. Option C (local people demanding removal) is not directly related to the dam's effectiveness as a hydroelectric structure. Option D (pollution and over - fishing) is more about water quality and resources rather than the dam's core function as a hydroelectric dam.

Answer:

A. They should expect that demand for the water will eventually ruin the dam’s effectiveness.
