Which of the following statements provides the most accurate investigation of why Ethiopia and Egypt have run into conflict over resources management?

1. Ethiopia’s building of a dam on the Nile could impact Egypt’s use of the Nile because they lie downriver.
2. Egypt’s use of fossil fuels causes an enormous amount of pollution to hang over Ethiopia’s cities, causing health issues.
3. Ethiopia’s construction of a power plant will pollute the river systems used by Egypt because they lie downriver.
4. Ethiopia’s use of fossil fuels to fuel economic growth frustrate Egypt, which shares the same scarce resources.

1. Ethiopia’s building of a dam on the Nile could impact Egypt’s use of the Nile because they lie downriver.

This statement provides the most accurate investigation of why Ethiopia and Egypt have run into conflict over resource management. The construction of the dam in Ethiopia can potentially affect Egypt's use of the Nile as they are located downstream. This issue has been a major point of contention between the two countries, leading to conflicts over water resources.

The most accurate investigation of why Ethiopia and Egypt have run into conflict over resources management is statement 1: Ethiopia’s building of a dam on the Nile could impact Egypt’s use of the Nile because they lie downriver.

To determine which statement provides the most accurate investigation of why Ethiopia and Egypt have run into conflict over resource management, let's analyze the options:

Statement 1 suggests that Ethiopia's construction of a dam on the Nile could impact Egypt's use of the river because Egypt lies downriver. This statement touches upon the Nile river being a shared resource and the potential implications of Ethiopia's dam on downstream countries like Egypt. It provides a relevant and plausible explanation for the conflict over resource management.

Statement 2 claims that Egypt's use of fossil fuels causes pollution that affects Ethiopia's cities and causes health issues. While this statement highlights a potential issue of pollution, it does not specifically address the conflict over resource management between the two countries.

Statement 3 asserts that Ethiopia's construction of a power plant will pollute the river systems used by Egypt since they are downstream. This statement is similar to statement 1 but focuses on the impact of a power plant rather than a dam. It provides valid reasoning for the conflict over resource management.

Statement 4 suggests that Ethiopia's use of fossil fuels frustrates Egypt due to the scarcity of resources they both share. This statement introduces the idea of shared resources but lacks specificity on how it relates to the conflict over resource management between the two countries.

Based on this analysis, statement 1, "Ethiopia’s building of a dam on the Nile could impact Egypt’s use of the Nile because they lie downriver," provides the most accurate investigation of why Ethiopia and Egypt have run into conflict over resource management. It directly addresses the construction of the dam, the shared resource, and the geographical impact on Egypt's use of the Nile.
