Example Input: Question: What character did THompkins voice in Dr. Katz, Professional Therapist? Passage:Tompkins has done voice work for many animated television series including Dr. Katz, Professional Therapist, King of the Hill, and Bob's Burgers, in which he voices the recurring character Randy. He lent his voice to a character in an unaired 2007 episode of Aqua Teen Hunger Force titled "Boston" that was supposed to be the premiere episode of the show's fifth season, but it was pulled by Turner Broadcasting System to avoid further controversy surrounding the 2007 Boston bomb scare. Tompkins later appeared in an episode during the show's 7th season. He was also the voice of one of the thugs in Walt Disney Animation Studios' 2010 computer animated film Tangled. Tompkins was the voice of Benton Criswell, a character in MTV series Super Adventure Team which featured marionettes in the style of the 1960s British series Thunderbirds; the role was credited under the stage name Francis Mt. Pleasant. He was the voice of a puppet in ads for the Ford Focus. Tompkins plays Mr. Peanutbutter in the 2014 Netflix original animated series BoJack Horseman. Tompkins voices the recurring character, Gladstone Gander, in the reboot series of DuckTales.

Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Example Input: Question: What is the age difference between the two rappers who performed in Victory? Passage:"Victory" is a song recorded by American hip hop recording artist Puff Daddy. The song was originally written by The Notorious B.I.G., Jason Phillips and Steven Jordan for his debut studio album No Way Out (1997). It features heavy use of mafioso-style lyrics, as was popular at the time. It features The Notorious B.I.G., who raps two verses, and Busta Rhymes, who raps the song's chorus. The song also heavily sampled the Bill Conti song "Going the Distance", which featured on the soundtrack to the movie Rocky making it a darker start to a rap album that featured many (at the time) club-standard singles. The song was released as a single in 1998, peaking at number 19 on the Billboard Hot 100. This song featured the very last verses recorded by The Notorious B.I.G. before his 1997 death as these verses were recorded a day before his shooting. The song was used for the EA Sports video game, Fight Night 2004, and the 2K Sports video game, NBA 2K13 by Puff Daddy and the Family featuring The Notorious B.I.G. and Busta Rhymes. This was re-used for the soundtrack of NBA 2K18.
