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.

Input: Consider Input: Passage: The film takes place in Minnesota, in 1990. Detective Bruce Kenner investigates the case of John Gray, who admits to sexually abusing his 17-year-old daughter Angela but has no recollection of the abuse. They seek the help of Professor Kenneth Raines to use recovered-memory therapy on John Gray to retrieve his memories, and come to suspect that their colleague Detective George Nesbitt is involved. They detain him but fail to find evidence against him. Detectives suspect a satanic cult is involved because of Angela's testimony, in which Angela says that she was abused by people in masks and someone took pictures of it.
Bruce and Kenneth meet Angela's estranged brother Roy Gray to inquire about why he left the house. Using the regression technique on him, he recalls hooded figures entering his room while he was young. Bruce and Kenneth suspect Roy's grandmother, Rose Gray, has some involvement but find nothing after a search of her house.
Meanwhile, Bruce begins having nightmares involving satanic rituals. Angela tells him that the cult is out to kill her as she has shown her demonic mark to him and that he is in danger as well. She tells him that her mother received miscellaneous calls and saw strange figures staring at her in the street before she met with an accident. Bruce starts to experience the same things and his nightmares increase in intensity.

Output: What is the name of John Gray's mother?


Input: Consider Input: Passage: Maiden Castle is an Iron Age hill fort 1.6 miles (2.6 km) south west of Dorchester, in the English county of Dorset. Hill forts were fortified hill-top settlements constructed across Britain during the Iron Age.
The earliest archaeological evidence of human activity on the site consists of a Neolithic causewayed enclosure and bank barrow. In about 1800 BC, during the Bronze Age, the site was used for growing crops before being abandoned. Maiden Castle itself was built in about 600 BC; the early phase was a simple and unremarkable site, similar to many other hill forts in Britain and covering 6.4 hectares (16 acres). Around 450 BC it was greatly expanded and the enclosed area nearly tripled in size to 19 ha (47 acres), making it the largest hill fort in Britain and, by some definitions, the largest in Europe. At the same time, Maiden Castle's defences were made more complex with the addition of further ramparts and ditches. Around 100 BC, habitation at the hill fort went into decline and became concentrated at the eastern end of the site. It was occupied until at least the Roman period, by which time it was in the territory of the Durotriges, a Celtic tribe.
After the Roman conquest of Britain in the 1st century AD, Maiden Castle appears to have been abandoned, although the Romans may have had a military presence on the site. In the late 4th century AD, a temple and ancillary buildings were constructed. In the 6th century AD the hill top was entirely abandoned and was used only for agriculture during the medieval period.
Maiden Castle has provided inspiration for composer John Ireland and authors Thomas Hardy and John Cowper Powys. The study of hill forts was popularised in the 19th century by archaeologist Augustus Pitt Rivers. In the 1930s, archaeologist Mortimer Wheeler and Tessa Verney Wheeler undertook the first archaeological excavations at Maiden Castle, raising its profile among the public. Further excavations were carried out under Niall Sharples, which added to an understanding of the site and repaired damage caused in part by the large number of visitors. Today the site is protected as a Scheduled Ancient Monument and is maintained by English Heritage.

Output: Who currently maintains Maiden Castle?


Input: Consider Input: Passage: In December 1775, Cletus Moyer is a free black Northerner in colonial America, working with a pre-Underground Railroad network to help slaves escape captivity. In the days just prior to Christmas, a group of bounty hunters led by Hattie Carraway captures Moyer near the Parker plantation in Spotsylvania County, Virginia. Because of his capture, dozens of slaves who have already left their plantations in escape attempts are in danger of being captured as well. Moyer implores two slaves from the nearby Reynolds plantation to take his place: Kunta Kinte, a Mandinka in his mid-twenties who was captured in what is now the Gambia, and Fiddler, an elderly man who was born into slavery. Kunta is eager to help (and to escape himself), but Fiddler is unwilling, fearful of the consequences if they are caught.
After an unsuccessful slave revolt elsewhere in the colony, Moyer and two slaves are hanged by Carraway's men on Christmas Eve, prompting Fiddler to set aside his fear and help Kunta lead the runaway slaves to freedom. Although the pair successfully leads the runaways that night to their next stop on the escape route (a boat waiting at the river) there is only room for one of them, and since neither one wants to go without the other, they both decide to stay.  That choice forces them to return to the Parker plantation and manufacture an excuse for their temporary absence. Nevertheless, Kunta and Fiddler are left with the satisfaction of knowing that they helped to give a group of fellow slaves the best Christmas gift of all: freedom.


Output: What's the first name of the person who dies the day before Christmas?
