200 175 150 125 100 75 50 25 0 Electricity (in thousands of MWh)  Amount of Additional Electricity Wind

Question

200 175 150 125 100 75 50 25 0 Electricity (in thousands of MWh)  Amount of Additional Electricity Wind Turbines Could Generate When Winds Were Stronger Than Forecast West Midwest The data for the 2 egories are as follows:� West: 150.2 thousand megawatt-hours Midwest: 182.6 thousand megawatt-hours Electric companies that use wind turbines rely on weather forecasts to predict the maximum amount of power, in megawatt-hours (MWh), they can generate using wind so that they can determine how much theyll need to generate from other sources. When winds are stronger than they were forecast to be, however, the predicted maximum amount of electricity wind turbines could generate will be too low. For example, the graph shows that for the West region, the winds were ______ blank Which choice most effectively uses data from the graph to complete the example?

Accepted Answer

Choice A is the best answer. The claim is that when winds are stronger than forecasted, wind turbines can generate more energy than predicted. The supporting graph shows the additional amount (above the predicted amount) that the turbines generated under those conditions, with the West generating about 150 thousand additional MWh. Choice B is incorrect. This choice doesn&rsquo;t complete the example. The graph shows the additional amount of electricity that the wind turbines generated. The West bar is greater than 0, so the West generated more than the predicted amount. Choice C is incorrect. This choice doesn&rsquo;t complete the example. The graph shows the additional amount of electricity that the wind turbines generated. The West bar is greater than 0, so the West generated more than the predicted amount. Choice D is incorrect. This choice misreads the graph. The graph shows us that the West (the bar on the left) generated about 150 thousand additional MWh.
