Example Input: Question: What other voice acting has the actor that voiced Aquaman done? Passage:Aquaman has guest starred in several episodes of the animated television series Justice League and Justice League Unlimited, where he was voiced by Scott Rummell. This version was based closely on the hot-headed antihero persona (the producers were aiming for "Conan underwater") of the 1994 and 2001 Aquaman comic book series, with the Viking-like appearance and hook prostheses. Here, he sacrificed his hand to save his infant son from being killed in a plot against his life by his evil brother Orm; Aquaman and his son were chained to a rock that was falling towards an underwater magma flow, and Aquaman only had time to free his right arm from his chains before cutting off his left hand to escape his remaining bonds. In the season two episode, "Hereafter", he is listed as a member of the Justice League on the Watchtower database after Superman was sent into the future. He later appeared in an homage episode alongside Superman, Batman, and Wonder Woman that pitted them against the Ultimen, modern pastiches of Samurai, Apache Chief, Black Vulcan, and the Wonder Twins from the Super Friends (Wind Dragon, Longshadow, Juice, Downpour, and Shifter, respectively). According to the website Television Without Pity, producers created Devil Ray and removed Aquaman and Black Manta from the series before the episode "To Another Shore" because the rights to Aquaman were no longer available due to an embargo on the characters because of the proposed and unaired Aquaman series.

Example Input: Question: How many seasons had Hallam played by the year Boulding joined their ranks? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 21 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17points above Carlisle United, the only side to be relegated out of The Football League.
