Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Who came second behind Diminuendo at The Oaks? Passage:In 1988 Melodist was ridden in all four of her races by Walter Swinburn. She did not run as a three-year-old until 22 May when she was sent to Italy for the Oaks d'Italia over 2400 metres on soft ground at the San Siro racecourse in Milan. The finish of the race was dominated by overseas challengers as Melodist won by one and a half lengths from her fellow British raider Asl (previously second in the Musidora Stakes) with the French-trained Summer Trip a neck away in third. On 9 July Melodist was one of nine runners to contest the Irish Oaks over one and a half miles at the Curragh and started at odds of 11/1. The 2/9 favourite for the race was Diminuendo, ridden by Steve Cauthen, who had won The Oaks by four lengths. Both Melodist and Diminuendo were owned by Sheikh Mohammed and based at Newmarket, but whereas Melodist was trained by Stoute, the favourite was trained by Henry Cecil at Warren Place. The other fancied runners were Dancing Goddess (second in the Irish 1000 Guineas), Miss Boniface (Ribblesdale Stakes) and Silver Lane (Prix de la Grotte). Melodist tracked the leaders before overtaking Miss Boniface before going to the front a furlong and a half from the finish. She faced a strong late challenge from Diminuendo and after a sustained struggle the two fillies crossed the line together with the judge declaring a dead heat.

Example Input: 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 2001–2003 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 2009–2012. 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.
