15. Why might hydroelectric dams cause conflicts between countries or regions? A They produce too much electricity for any one area to manage. B. They can lead to disagreements over access to water during shortages. C They require relocation of people in urban areas. They reduce the availability of fresh water for agricultural purposes.

## Step 1<br />The question is asking why hydroelectric dams might cause conflicts between countries or regions. The options provided are:<br />A. They produce too much electricity for any one area to manage.<br />B. They can lead to disagreements over access to water during shortages.<br />C. They require relocation of people in urban areas.<br />D. They reduce the availability of fresh water for agricultural purposes.<br /><br />## Step 2<br />We need to analyze each option in relation to the question. <br /><br />## Step 3<br />Option A suggests that hydroelectric dams produce too much electricity for any one area to manage. While this could potentially cause issues, it is not the primary reason for conflicts between countries or regions.<br /><br />## Step 4<br />Option B suggests that hydroelectric dams can lead to disagreements over access to water during shortages. This is a plausible reason for conflicts, as water is a vital resource for many countries and regions.<br /><br />## Step 5<br />Option C suggests that hydroelectric dams require relocation of people in urban areas. While this could cause issues, it is not the primary reason for conflicts between countries or regions.<br /><br />## Step 6<br />Option D suggests that hydroelectric dams reduce the availability of fresh water for agricultural purposes. While this could cause issues, it is not the primary reason for conflicts between countries or regions.
