Passage: The end of the Middle Ages brought with it a waning of interest in King Arthur. Although Malory's English version of the great French romances was popular, there were increasing attacks upon the truthfulness of the historical framework of the Arthurian romances established since Geoffrey of Monmouth's time and thus the legitimacy of the whole Matter of Britain. So, for example, the 16th-century humanist scholar Polydore Vergil famously rejected the claim that Arthur was the ruler of a post-Roman empire, found throughout the post-Galfridian medieval "chronicle tradition", to the horror of Welsh and English antiquarians. Social changes associated with the end of the medieval period and the Renaissance also conspired to rob the character of Arthur and his associated legend of some of their power to enthrall audiences, with the result that 1634 saw the last printing of Malory's Le Morte d'Arthur for nearly 200 years. King Arthur and the Arthurian legend were not entirely abandoned, but until the early 19th century the material was taken less seriously and was often used simply as a vehicle for allegories of 17th- and 18th-century politics. Thus Richard Blackmore's epics Prince Arthur (1695) and King Arthur (1697) feature Arthur as an allegory for the struggles of William III against James II. Similarly, the most popular Arthurian tale throughout this period seems to have been that of Tom Thumb, which was told first through chapbooks and later through the political plays of Henry Fielding; although the action is clearly set in Arthurian Britain, the treatment is humorous and Arthur appears as a primarily comedic version of his romance character. John Dryden's masque King Arthur is still performed, largely thanks to Henry Purcell's music, though seldom unabridged.
Question: What is the full name of the person Vergil rejected as the ruler of a post-Roman empire?

Ex Output:
King Arthur.

Passage: The movie begins with a scooter chase between Harry and his nan because she didn't know it was him. Afterwards, Harry is sent to get a chicken for lunch, but they fire a machine gun at him and throw a grenade, which Harry throws into the chicken shed, blowing them up. Nan tells Harry the story of his twin brother, Otto, which Harry claims to have heard before.
Suddenly, Harry and Nan then discover that their beloved pet hamster Abu is ill after he vomits a green substance on them, so they take him to the vet. He is almost put down until Harry takes him back home. Ed the vet and his assistant, Kisko, are working for Harry's neo-Nazi twin brother Otto who was abandoned by Nan in the 1970s, claiming it was because she couldn't look after them both, and was raised by Alsatians.
After another failed attempt to capture Abu (by disguising as a priest and a nun), Harry and Nan decide to take him on a trip in their Rover P6 to Blackpool for a week before he dies (when Abu really wanted to visit the home of Rihanna). Ed and his assistant pursue them on the road, until they arrive in "Blackpole" by mistake. The next day, Harry and Nan take Abu on a personal guided tour around the nuclear power plant by the cleaner. Ed and Kisko attempt to capture him again only for him to end up turned into a destructive giant caused by radiation which wears off shortly. While walking on the beach they encounter Barney Cull, a member of the Shell People.
Question: What are the first names of Nan's grandchildren?

Harry.

Passage: In 1933, Freya Roth is a young German girl engaged to a Nazi party member. When she realizes the true nature of his political views she breaks the engagement and turns her attention to anti-Nazi Martin Breitner. Her father, Professor Roth, does not abide by the attitude of the new order towards scientific fact.
Though his stepsons Erich and Otto eagerly embrace the regime, Professor Roth's reluctance to conform leads at first to a boycott of his classes and eventually to his arrest and a sentence of forced physical labor. His wife is permitted a five-minute visit in which the professor urges her to take Freya and her younger brother and leave the country. He dies soon after.
Freya is kept from leaving by Nazi officials suspicious of her father's work. She reunites with Martin and together they attempt to escape through a mountain pass. A squad reluctantly led by her former fiancee gives chase and Freya is fatally wounded, dying in Martin's arms just after they cross the border. Later, Erich and Otto are informed of their sister's death. Erich responds with anger towards Martin. Otto, however, experiences an epiphany, and flees their once-happy home, rejecting the Nazis and their cruel doctrine.
Question: Who is Erich and Otto's stepfather?

Ex Output:
Professor Roth.
