Fossil fuel plants and nuclear plants both heat water in order to turn __ A. reserves B. windmills C. solar panels D. turbines

## Step 1<br />The problem is asking us to identify what both fossil fuel plants and nuclear plants heat water to turn. The options provided are reserves, windmills, solar panels, and turbines.<br /><br />## Step 2<br />We know that both fossil fuel plants and nuclear plants generate electricity by heating water to produce steam. This steam is then used to turn turbines, which generate electricity.<br /><br />## Step 3<br />The options reserves, windmills, and solar panels do not fit the context of the problem. Reserves are not turned by heating water, windmills are turned by wind, and solar panels convert sunlight into electricity.
