PROBLEM: Question: How many teams were a part of the league that ran from 2001-2003 and featured many World Cup stars? Passage:The first women's professional soccer league in the U.S. formed after the success of the 1999 Women's World Cup. The Women's United Soccer Association (WUSA) ran from 20012003 and featured many of the World Cup stars, including Mia Hamm, Michelle Akers and Brandi Chastain. Its successor Women's Professional Soccer (WPS) ran from 20092012. Currently, the National Women's Soccer League (NWSL) is the top professional league in the country and was formed in 2012. The NWSL season runs from spring to early fall (typically April October). In 2017, A&E Networks bought an equity stake in the league and broadcasts a game of the week on Lifetime, and formerly streamed all games online via the go90 platform. During the 2018 season, the NWSL moved some of the games originally scheduled to air on Lifetime to evening slots on ESPNews (both channels being part of the Disney family), and when go90 owner Verizon shut down that platform at the end of July, the NWSL streamed the games that were intended for go90 on its own website.

PROBLEM: Question: How many goals did Otto Addo score for Borussia Dortmund during his time with the team? Passage:In 1998, Hannover finally promoted to the Second Bundesliga. In his first season, he scored seven goals in 30 games and was acknowledged as one of the elite players of the league. He then transferred to Borussia Dortmund in 1999 and played more than 75 times for the team, becoming German champion in 2002. However, he was also hampered by great injury troubles, as he tore his cruciate ligaments three times in this time, the first coming after a German Cup match against SC Freiburg on 15 July 2001. The player had an MRI scan which showed he had torn knee ligaments and underwent surgery on his right knee on 22 July at the Vail, Colorado clinic of world-renowned knee specialist surgeon Dr. Richard Steadman. He healed completely after that, and came back to play the 2002 UEFA Cup Final for Dortmund against Feyenoord Rotterdam on 8 May 2002, which Dortmund lost 32 at the Feijenoord Stadion in Rotterdam. On 7 September 2002, Addo tore right knee ligaments for the second time, in a 2004 African Cup of Nations qualifier versus Uganda in Kampala.
