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: Which city had a greater population the year Gordon led his regiment to the Battle of Marks' Mills, Little Rock or Camden? Passage:In March and April 1864, Shelby's men harassed and skirmished with the Union Army force under the command of Major General Frederick Steele during his Camden Expedition, part of the Red River Campaign. Gordon led more than one charge against the Union forces during Steele's march from Little Rock to Camden, Arkansas. On April 25, 1864, Gordon led his regiment at the Battle of Marks' Mills where they captured two Union artillery pieces from the detachment of Union Lieutenant Colonel Francis M. Drake when Shelby's force attacked the Union left wing of the detachment which had been sent from Camden toward Pine Bluff, Arkansas to obtained supplies for Steele's force which was increasingly besieged by gathering Confederate forces at Camden. The Confederates outnumbered the Union force at Marks' Mills by more than 2 to 1 and overwhelmed it, taking about 1,300 prisoners and about 240 wagons. The overall commander of the Confederate cavalry force at Marks' Mills, Brigadier General James Fagan, led the Confederates, including Shelby's command, toward Pine Bluff in an effort to capture the Union supply depot. The Confederates did not make it to Pine Bluff due to flooding. They also did not return fast enough to cut off Steele's return march to Little Rock or to participate in the Battle of Jenkins' Ferry, the one big engagement during the retreat before the Union troops escaped across the swollen Saline River.

Example Input: Question: How much money was made at the box office by the 1997 David Lynch movie that Mason contributed 2 songs to? Passage:Neil Strauss, a rock critic and reporter for The New York Times, met Marilyn Manson through his work for Spin and Rolling Stone. Strauss initially perceived Manson as a "phony" who had gotten on the gothic rock bandwagon very late; he later came to see Manson as a "really interesting, really intelligent artist" with many talents. He went to talk to Manson at a Holiday Inn in Fort Lauderdale, Florida. Manson asked Strauss to join him in a hot tub, commenting "This is going to be an important piece of press." Strauss wrote a cover story about Manson for Rolling Stone, which in the view of the Chicago Reader Jim DeRogatis "legitimized Manson's emergence as one of the most notorious entertainers of the 90s and an enthusiastic bogeyman for the right". Following the publication of the article, Strauss became Manson's business partner. Later, Manson and Strauss got a deal to write the singer's autobiography for ReganBooks, an imprint of HarperCollins founded by Judith Regan, who was behind Howard Stern's Private Parts (1997). The autobiography shares its title with the Marilyn Manson song "Long Hard Road Out of Hell" (1997) and features an introduction written by film director David Lynch; Manson had previously contributed two songs to the soundtrack of Lynch's film Lost Highway (1997) and would later collaborate with the director on a coffee table book titled Genealogies of Pain (2011).

Example Input: Question: Who was the founder of Champs Sports? Passage:Many store closings ensued at the mall in the early 1990s, including five chain clothing stores and a T.J. Cinnamons bakery all in late 1991 and early 1992. Despite these closures, the mall also gained Champs Sports and a dollar store, and its occupancy level of 92 percent was higher than the average occupancy rate of 85 percent for malls in the Midwestern United States at the time. Limited Brands (now L Brands) opened three stores then under its ownership in 1993: a combination Limited Express/Structure store (now known as Express and Express Men, respectively) and Victoria's Secret. The combined Limited Express/Structure took the place of Herman's World of Sporting Goods, which had closed earlier in the year. According to the mall's then-general manager, Limited Brands had wanted to open all three brands at the mall for several years, and that all three were highly demanded by shoppers due to their presence at Meridian Mall. Following these additions, Lansing and Meridian malls had nearly 60 stores in common with each other and nearly 40 others that were unique to each. In 1995, the mall received new planters and an enlarged customer service booth. Meanwhile, RadioShack and Regis Hairstylists moved to new storefronts, Lane Bryant expanded its existing store, and Buckle, Bombay Company, and Pacific Sunwear joined. These were followed in 1996 by Gymboree, Bath & Body Works, and the second Disney Store in the state of Michigan.
