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: Ted and Larry studied environmental sciences. They are learning about greenhouse gasses this week. Ted reads about carbon dioxide, while Larry reads about methane gas. 
Question: Which student read more about carbonic acid?
Output (English): Ted.
