5. In 2012 in the United States, most electricity was generated from coal (37%), natural gas (30%), or nuclear power plants (19%). Hydropower accounted for 7% of the total electricity produced; otherrenewable sources such as wind or solar power accounted for 5%. Other nonrenewable sources (such as petroleum) made up the remaining 2%. Complete parts a through d below.a. Display the information in a bar graph. The bars, from left to right, represent coal, natural gas, nuclear power, hydropower, wind or solar, and other nonrenewable sources.

A pie chart is easier because estimating the sizes of the slices in a pie chart is easier than estimating the heights of the bars in a bar graph.B. A bar chart is easier because sketching the exact percentages is more challenging in a pie chart.C. A bar chart is easier because the bars are always in decreasing order of category percentages, which makes comparisons of categories easier.D. A pie chart is easier because a pie chart has one shape (a circle), which is easier to graph more accurately than a bar graph, which has multiple shapes (multiple rectangles). The accompanying bar graph is from a study investigating the factors that influence alligators' choice of food. For 219 alligators captured in fourdifferent lakes, researchers classified the primary food choice (in volume) found in the alligator's stomach in one of the categories-fish, invertebrate,reptile, bird, or other.Use the bar graph to complete parts a through d.OtherReptileFishBirdc.
