Task: Question Answering
Input (English): Passage: The test game was played in Rockford, Illinois, at the Rockford MetroCentre. Sponsors were secured, and players and coaches from local colleges were recruited to volunteer to play for the teams, the Chicago Politicians and Rockford Metros, with the guarantee of a tryout should the league take off. Interest was high enough following the initial test game that Foster decided to put on a second, "showcase", game. The second game was held on February 26, 1987 at the Rosemont Horizon in Chicago with a budget of $20,000, up from $4,000 in the test game. Foster also invited ESPN to send a film crew to the game; a highlights package aired on SportsCenter. Question: The second test game was played in what arena?
Output (English): Rosemont Horizon
