Carbon pollution from the burning of fossil fuels has contributed to the warming of the planet, which has melted ice in the Arctic Circle and unearthed caves and waterways that were previously inaccessible due to ice. Scientists researching these areas have found stores of carbon that had been trapped in the permafrost of these caves, and that are now being spread into the atmosphere by bacteria as the permafrost melts.
Which of the following can best be concluded by the information above?
a) The rate at which carbon is being released into the atmosphere is increasing.
b) Previously frozen carbon from permafrost will someday pose more of a threat to the environment than the carbon released from the burning of fossil fuels.
c) The amount of carbon being released into the atmosphere cannot be determined simply by calculating the amount of fossil fuel being burned.
d) The amount of carbon released into the atmosphere will increase until humans stop burning fossil fuels.
e) The amount of carbon released into the atmosphere from melting permafrost is about equal to the amount released from the burning of fossil fuels."‹
