instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
Passage: Charlemagne planned to continue the Frankish tradition of dividing his kingdom between all his heirs, but was unable to do so as only one son, Louis the Pious (r. 814–840), was still alive by 813. Just before Charlemagne died in 814, he crowned Louis as his successor. Louis's reign of 26 years was marked by numerous divisions of the empire among his sons and, after 829, civil wars between various alliances of father and sons over the control of various parts of the empire. Eventually, Louis recognised his eldest son Lothair I (d. 855) as emperor and gave him Italy. Louis divided the rest of the empire between Lothair and Charles the Bald (d. 877), his youngest son. Lothair took East Francia, comprising both banks of the Rhine and eastwards, leaving Charles West Francia with the empire to the west of the Rhineland and the Alps. Louis the German (d. 876), the middle child, who had been rebellious to the last, was allowed to keep Bavaria under the suzerainty of his elder brother. The division was disputed. Pepin II of Aquitaine (d. after 864), the emperor's grandson, rebelled in a contest for Aquitaine, while Louis the German tried to annex all of East Francia. Louis the Pious died in 840, with the empire still in chaos.A three-year civil war followed his death. By the Treaty of Verdun (843), a kingdom between the Rhine and Rhone rivers was created for Lothair to go with his lands in Italy, and his imperial title was recognised. Louis the German was in control of Bavaria and the eastern lands in modern-day Germany. Charles the Bald received the western Frankish lands, comprising most of modern-day France. Charlemagne's grandsons and great-grandsons divided their kingdoms between their descendants, eventually causing all internal cohesion to be lost. In 987 the Carolingian dynasty was replaced in the western lands, with the crowning of Hugh Capet (r. 987–996) as king. In the eastern lands the dynasty had died out earlier, in 911, with the death of Louis the Child, and the selection of the unrelated Conrad I (r. 911–918) as king.The breakup of the Carolingian Empire was accompanied by invasions, migrations, and raids by external foes. The Atlantic and northern shores were harassed by the Vikings, who also raided the British Isles and settled there as well as in Iceland. In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish King Charles the Simple (r. 898–922) to settle in what became Normandy. The eastern parts of the Frankish kingdoms, especially Germany and Italy, were under continual Magyar assault until the invader's defeat at the Battle of Lechfeld in 955. The breakup of the Abbasid dynasty meant that the Islamic world fragmented into smaller political states, some of which began expanding into Italy and Sicily, as well as over the Pyrenees into the southern parts of the Frankish kingdoms.

question:
Passage: Will Maddox has a theory about students not liking the idea of school and authority and thinking that it is a prison. He tests this theory and examines the boundaries of authority and his friendships. A few years before, a student, John Stanton was committed to an insane asylum, reasons unknown to most everybody except the principal. One day he escapes, releasing everyone else from the asylums around. Maddox sees this defiance which is the start of his anarchy. Maddox wants to "help him" and understand him more so they start a correspondence and Stanton tells him what to do and how to do them. This is includes the erasing of student grades, posting posters/fliers, locking part of the student body in a room among other things. Maddox gets his friends involved and challenges authority and gets most of the school behind him, including an administrator for a while. He is so consumed with creating chaos and disorder that his friends start to see the destruction, but they have to save themselves, and him before he can take complete control over the school.
answer:
What is the full name of the person who must be stopped before they take over the school?


question:
Passage: After the untimely death of a small-town church choir director in Pacashau, Georgia, Vi Rose Hill, a no-nonsense mother raising two teens alone, takes control of the choir using the traditional Gospel style that their Pastor Dale approves of. However, the director's widow, G. G. Sparrow, the main benefactor to the church, believes she should have been given the position. As in previous years, the choir reaches the regional finals of the national amateur "Joyful Noise" competition, only to be disappointed when a rival choir beats them. Tough times in the town have led to budget problems that threaten to close down the choir, at the same time as the town needs the choir's inspiring music more than ever.
Vi Rose has a son, Walter, who has Asperger syndrome, and a talented, pretty and ready-to-date daughter, Olivia. But Olivia is not ready to date under her mother's household rules. G. G. has recently begun caring for her rebellious, drifter grandson, Randy. A romance blossoms between Olivia and Randy, which is strongly opposed by Vi Rose. Olivia also has a rival suitor, Manny. At Randy's urging, G. G., Olivia and most of the choir come to believe that some more contemporary arrangements (prepared by Randy) would be more successful for the choir. It also turns out that the choir has a chance at the national finals of the competition when the rival choir is found to have cheated by hiring professionals. But the pastor says that the church will not sponsor the choir unless they continue to use their reverent, traditional style.
answer:

Whose grandson wrote music?
