Task: Question Answering
Input (English): Since we were also interested in whether argumentation differs across registers, we included four different registers — namely (1) user comments to newswire articles or to blog posts, (2) posts in discussion forums (forum posts), (3) blog posts, and (4) newswire articles.  
 Question: How is the data in the new corpus come sourced?
Output (English): user comments to newswire articles or to blog posts forum posts blog posts newswire articles
