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.

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.

Passage: Eleven year old Randy Daytona becomes anxious when he learns that his father Peter has bet on his performance in the 1988 Summer Olympics table tennis finals. During his first game between his opponent Karl Wolfschtagg from the German Democratic Republic, Daytona has an accident and suffers an injury. Unable to continue, he loses the match. Loan sharks, in the employ of criminal mastermind Feng, murder his father, and Daytona leaves competitive ping-pong.
Nineteen years later, Daytona is dismissed from the Peppermill casino and meets FBI agent Ernie Rodriguez, who requests his assistance in arresting Feng for running guns. Feng's hidden jungle hideout hosts a black-market Ping-Pong tournament, and Daytona's invitation is a way for the FBI to infiltrate Feng's organization. When Daytona agrees, Rodriguez tells him to win enough championships that Feng's scouts notice him. After losing a local tournament, Daytona is apprenticed to a blind man in Chinatown named Wong, who was Feng's former mentor. Daytona also meets Wong's niece, Maggie. When locals vandalize Master Wong's house for violating their edict against teaching white people ping pong, Daytona is forced to play against "The Dragon", a young girl, in exchange for Wong's right to stay. After Daytona beats the Dragon, Feng's men take notice of his win and bring Daytona, Rodriguez, and Wong to Feng's facility.

Passage: James Barton Longacre was born on a farm in Delaware County, Pennsylvania, on August 11, 1794. His mother Sarah (Barton) Longacre died early in his life; his father, Peter Longacre, was the descendant of early Swedish settlers of North America. When Peter Longacre remarried, his son found the home life intolerable, and James Longacre left home at the age of 12, seeking work in the nearby city of Philadelphia. He apprenticed himself at a bookstore; the owner, John E. Watson, took the boy into his family. Over the following years, Longacre worked in the bookstore, but Watson realized that the boy's skill was in portraiture. Watson granted Longacre a release from his apprenticeship in 1813 so that he could follow an artistic muse, but the two remained close, and Watson would often sell Longacre's works.Longacre became apprenticed to George Murray, principal in the engraving firm Murray, Draper, Fairman & Co. at 47 Sansom Street in Philadelphia. This business derived from the firm established by the Philadelphia Mint's first chief engraver, Robert Scot. Longacre remained at the Murray firm until 1819; his major work there was portraits of George Washington, Thomas Jefferson, and John Hancock which were placed on a facsimile of the Declaration of Independence by publisher John Binns; the work cost Binns a total of $9,000 (equal to $147,307 today). Also employed at the Murray firm from 1816 was the man who would be Longacre's predecessor as chief engraver, Christian Gobrecht. Longacre's work at the company gave him a good reputation as an engraver skilled in rendering other artists' paintings as a printed engraving, and in 1819, he set up his own business at 230 Pine Street in Philadelphia.Longacre's first important commission were plates for S.F. Bradford's Encyclopedia in 1820; an engraving of General Andrew Jackson by Longacre based on a portrait by Thomas Sully achieved wide sales. Longacre then agreed to engrave illustrations for Joseph and John Sanderson's Biographies of the Signers of the Declaration of Independence, published in nine volumes between 1820 and 1827. Although the venture was marked by criticism of the writing, sales were good enough that the project was completed. Numismatic writer Richard Snow suggests that the books sold on the strength of the quality of Longacre's illustrations. Longacre also completed a series of studies of actors in their roles in 1826 for The American Theatre.
