Hello! What can you tell me about sports in Chicago? 
 Hello. Sporting News named Chicago the Best "Sports City" in the United States. In 1993,2006 and 2010. 
 Oh wow! What makes them so great? 
 Chicago is the only city, along with Boston; to continuously host major professional sports since 1871. Except in 1872 and 1873, due to the Great Chicago Fire. 
 Do you know what is one of the sports there? 
 They have a Major League Baseball team, The Cubs. They started in 1871 until the Great Chicago Fire. Then it started back continuously in 1874. 
 Oh nice! What can you tell me about history of Chicago? 
 Before the Illinois and Michigan Canal opened in 1848. Galena and Chicago Union Railroad was Chicago's first railway. 
 Oh i see, what else? 
 The city's primary freshwater source was polluted. Due to untreated sewage and industrial waste flowing into the Chicago River, and subsequently into Lake Michigan.
