Question

This pie chart presents data on sources of methane emissions in the United States between 1990 and 2013. Which questions would help clarify the evidence in the chart? (Note: Enteric fermentation is a way that some animals digest food.)

Answer 1

The question that will help to clarify the evidence in the chart is this: WHAT ARE THE OTHER SOURCES OF METHANE GAS THAT ARE RESPONSIBLE FOR 8% OF EMISSIONS.
From the pie chart given above, it can be seen that for all other values given, the processes that generate the methane gas was given except for that of other, which has the value of 8%. Knowing the processes that generate this percentage of methane gas will add more information to the pie chart.<span />
