In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. 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: 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.

Example Input: Question: Which company manufactured the rifle that the Bundeswehr replaced in 1997? Passage:The Heckler & Koch G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine. The G36 was made with the extensive use of lightweight, corrosion-resistant synthetic materials in its design; the receiver housing, stock, trigger group (including the fire control selector and firing mechanism parts), magazine well, handguard and carry handle are all made of a carbon fiber-reinforced polyamide. The receiver has an integrated steel barrel trunnion (with locking recesses) and a nylon 66 steel reinforced receiver. The standard German Army versions of the G36 are equipped with unique a ZF 3×4° dual optical sight that combines a 3× magnified telescopic sight and an unmagnified reflex sight mounted on top of the telescopic sight. Widely distributed, it has been adopted by over 40 countries and prompted other nations to develop similar composite designs, such as the FX-05 Xiuhcoatl.

Example Input: Question: Which of the cities Runyon traveled with Blanco's forces to was larger? Passage:Runyon opened a commercial photography studio in 1910. He initially photographed urban life Brownsville and Matamoros, Tamaulipas and the surrounding terrain of the Rio Grande Valley. In 1913, Runyon began recording the events of the Mexican Revolution, starting with the takeover of the Matamoros garrison by the Constitutional Army under General Lucio Blanco on June 3. He traveled with Blanco's forces to Ciudad Victoria and later Monterrey. In 1915, Runyon was the only professional to photograph two skirmishes by Mexican bandits on American soil, the Norias Ranch Raid and a train derailment near Olmito, Texas. He took more than 2,000 pictures of Fort Brown, which captured troop buildup and mechanization in preparation for World War I. Runyon returned to more traditional subjects in the border region, as well as portraits and postcards, following the end of the war.
