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 that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn’t release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. 
Story: Bob is trying to move to an area with low pollution. He has done his research and narrowed it down to two cities. Seattle, which has a nuclear power plant, and St. Louis which has a coal powered power plant. Both cities seem to have similar commercial and industrial areas, and only differ in the type of power they generate. 
Question: Which city should Bob choose to move to in keeping with his goals?
Output (English): Seattle.
