7 A power company wants to build a new electric power plant next to a river and use water from the river for cooling. Which of the following should be studied before deciding whether to let the company build the plant? A. The efficiency of the generators that the company plans to build. The power company's contribution.to support local sports teams. The effects of warmer water on the fish species that live in the river The price of the high-voltage wires used to transmit.

## Step 1<br />The problem presents a scenario where a power company wants to build a new electric power plant next to a river and use water from the river for cooling. The question asks us to identify which of the given options should be studied before deciding whether to allow the company to build the plant.<br /><br />## Step 2<br />The options provided are:<br />A. The efficiency of the generators that the company plans to build.<br />B. The power company's contribution to support local sports teams.<br />C. The effects of warmer water on the fish species that live in the river.<br />D. The price of the high-voltage wires used to transmit.<br /><br />## Step 3<br />We need to consider the potential environmental impact of the power plant's construction and operation. The efficiency of the generators (option A) and the price of the high-voltage wires (option D) are important for the company's operations, but they do not directly impact the environment.<br /><br />## Step 4<br />The power company's contribution to local sports teams (option B) is a social issue and does not have a direct impact on the environment.<br /><br />## Step 5<br />The effects of warmer water on the fish species that live in the river (option C) are directly related to the environment. If the power plant's cooling process increases the river's temperature, it could harm the fish species living in the river.
