Task: Question Answering
Input (English): Background Paragraph: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions – primarily from use of fossil fuels and deforestation – have rapidly increased its concentration in the atmosphere, leading to global warming.  Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. 
Story: Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere. 
Question: Which county generated more anthropogenic emissions?
Output (English): Brown.
