Task: Question Answering
Input (English): Background Paragraph: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. 
Story: In the town of Hawkings they get all of their power from a Nuclear power plant. Across the country another town called Gideon relies solely on the burning of fossil fuels. Gideon intents to switch to nuclear power soon. 
Question: Given Gideon goes through with its plan to switch to nuclear power, will the amount of air pollution it creates increase or decrease?
Output (English): decrease.
