Because of the connection between greenhouse gases and climate change, there has been a concerted effort to reduce greenhouse gas emissions. How does this second graph, published by the EPA, support the growing trend in reducing these emissions? A) The second graph shows that the electricity generation sector has done a good job at substantially reducing the emission of all greenhouse gases. B) The top graph shows the greatest fluctuations in carbon dioxide. The second graph shows that there has been little change if any in the emissions by each sector. C) It does not support the idea that there is a great reduction in any sector of greenhouse gases. The lines in the second graph remain reasonably flat throughout the sectors in the graph. D) Of greatest concern is carbon dioxide emissions as seen in the top graph. In the second graph, the electricity generation and transportation sectors have reduced the emissions slightly.
