[EX Q]: 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.

[EX Q]: Question: Which countries comprised the alliance that conquered and occupied Greece? Passage:Aside from the Romaniotes, a distinct Jewish population that historically lived in communities throughout Greece and neighboring areas with large Greek populations, Greece had a large population of Sephardi Jews, and is a historical center of Sephardic life; the city of Salonica or Thessaloniki, in Greek Macedonia, was called the "Mother of Israel". Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers despite efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States.

[EX Q]: Question: How large is the park in Wanstead that is part of Epping Forest? Passage:The main road going through Wanstead is the A12 and was the site of a Roman villa, whilst Wanstead Manor was a Saxon and Norman manor. It formed part of the Municipal Borough of Wanstead and Woodford in Essex from 1937 until 1965, when Greater London was created. The area has a largely suburban feel, containing open grasslands such as Wanstead Flats, and the woodland of Wanstead Park, part of Epping Forest. The park, with artificial lakes, was formerly part of the estate of a large stately home Wanstead House, built by Richard Child, 1st Earl Tylney, one of the finest Palladian mansions in Britain and the architectural inspiration for Mansion House, London. It was subsequently demolished to pay the gambling debts of a relation of the Duke of Wellington.
