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


question:
Passage: The Balts were largely driven to unite by external threats from aggressive German religious orders. In 1202, the Order of the Livonian Brothers of the Sword was established by Albert, the Bishop of Riga, to promote the Christianization and conquest of the Livonians, Curonians, Semigallians, and Estonians near the Gulf of Riga. The Order waged a number of successful campaigns and posed a great danger to the Lithuanian territories. The Order's progress was halted by its defeat at the Battle of Saule in 1236, after which it almost collapsed. The following year, it merged into the Teutonic Knights.In 1226, Konrad I of Masovia invited the Teutonic Knights to defend his borders and subdue the Prussians, offering the Knights the use of Chełmno (Kulm) as a base for their campaign. In 1230, they settled in Chełmno, built a castle, and began attacking Prussian lands. After 44 years, and despite two Prussian uprisings against them, they had conquered most of the Prussian tribes. Afterwards, the Knights spent nine years conquering the Nadruvians, Skalvians, and Yotvingians, and from 1283, they were better positioned to threaten the young Lithuanian state from the west.
Further unification of the Lithuanian tribes was facilitated by the social changes that took place in Lithuania during this period. Private land ownership was established (allodiums, Lithuanian: atolai), which would later evolve into a feudal system. As attested by many chronicles, it was the principal form of organization governing land ownership in the 13th century. Under this system, known in England as primogeniture, only the eldest son could inherit lands, which allowed dukes to consolidate their holdings. Social classes and divisions of labor also began taking shape. There were classes of experienced soldiers (bajoras), of free peasants (laukininkas), and of "unfree" people (kaimynas and šeimynykštis). In order to enforce this social structure, a united state was needed. Another force behind unification was the desire to take advantage of Ruthenian lands, which were suffering from the Mongol invasion. Temporary alliances among Lithuanian dukes often sufficed for military ventures into, and plundering of, these lands (including Pskov, plundered in 1213). Altogether, between 1201 and 1236, Lithuanians launched at least 22 incursions into Livonia, 14 into Rus, and 4 into Poland. The ongoing administration of conquered territories, however, required a strong and unified central power.
answer:
What is the full name of the group that posed a great danger to the Lithuanian territories and waged a number of successful campaigns?


question:
Passage: A show composed of a concert, circus acts, and broadway is taking place at a theater in the city. One of the stars of the show is a lady cat dancer whom Oswald suddenly has affection for upon seeing a poster. For admission, patrons have to pay 50 cents. Unfortunately for Oswald, his pockets are empty.
Oswald notices a stage entrance where performers and certain officials can come in, and admission is unnecessary. Because of this, Oswald comes up with an idea of impersonating a performer by bulging his chest (possibly pretending to be a stuntman). The guard by the door isn't deceived and prevents the penniless rabbit from coming in. After a bit of a struggle, Oswald ties the guard to a lamp post and proceeds toward the inside of the theater. However, he is forced back outside by the glaring performers.
While thinking of a way to get back in, Oswald sees a man in a thick fur coat coming out of a taxi and heading towards the theater entrance. Oswald hides under the man's shadow. As the man with the coat enters, the guard becomes suspicious upon noticing a lump on the shadow. Thinking he made it inside undetected, Oswald comes out but doesn't notice the guard approaching him. When he realizes the guard was right behind him, Oswald quickly makes his move.
Oswald prevails in losing the guard by going inside a cage. However, he is met with more trouble when the cage contains a jaguar. The jaguar chases him into the stage where acrobats are doing a balancing act with a long pole. Oswald climbs up the pole and grabs the ceiling for his safety. One of the acrobats also goes up the pole and clings onto the rabbit's legs. Bothered by having someone hanging under him, Oswald grabs a mallet and strikes off the acrobat. Oswald plunges down and drops on the jaguar. The jaguar is angered more than ever and the frightened Oswald flees the stage.
answer:

Who thinks they made it inside undetected?
