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: In the late 19th and early 20th centuries, child vaudevillian Buster Keaton stays in boarding houses, rides in train boxcars, and performs with his mother and father in a knock-about (physical comedy) act called The Three Keatons. As a young man Keaton travels on his own to Hollywood and tricks his way onto the grounds of silent-film studio Famous Studio as a workman carrying a board, as in one of his trademark comic bits.
Sneaking onto a set, he attracts the attention of a young casting director, Gloria Brent. He demonstrates his type of physical comedy to a director Kurt Bergner, whom he does not impress. But Gloria recognizes his talent and recommends him to studio head Larry Winters, who offers him a contract. Keaton begins to get small parts in other people's pictures. As his comic talent becomes more apparent and his fame and money-making power grows, he is offered a contract to direct and star in his own silent films.
Dissatisfied with not sharing the profits of his films, he is told that he must invest in his own pictures in order to profit-share. He does in "The Gambler", which is released at the same time as Al Jolson's blockbuster talkie, "The Jazz Singer", reducing public interest in it. Buster struggles to adapt to performing in talking pictures.
What is the full name of the person who fails to impress Kurt Bergner?

Passage: On 21 January 1818, Friedrich married Caroline Bommer, the twenty-five-year-old daughter of a dyer from Dresden. The couple had three children, with their first, Emma, arriving in 1820. Physiologist and painter Carl Gustav Carus notes in his biographical essays that marriage did not impact significantly on either Friedrich's life or personality, yet his canvasses from this period, including Chalk Cliffs on Rugenpainted after his honeymoondisplay a new sense of levity, while his palette is brighter and less austere. Human figures appear with increasing frequency in the paintings of this period, which Siegel interprets as a reflection that "the importance of human life, particularly his family, now occupies his thoughts more and more, and his friends, his wife, and his townspeople appear as frequent subjects in his art."Around this time, he found support from two sources in Russia. In 1820, the Grand Duke Nikolai Pavlovich, at the behest of his wife Alexandra Feodorovna, visited Friedrich's studio and returned to Saint Petersburg with a number of his paintings, an exchange that began a patronage that continued for many years. Not long thereafter, the poet Vasily Zhukovsky, tutor to Alexander II, met Friedrich in 1821 and found in him a kindred spirit. For decades Zhukovsky helped Friedrich both by purchasing his work himself and by recommending his art to the royal family; his assistance toward the end of Friedrich's career proved invaluable to the ailing and impoverished artist. Zhukovsky remarked that his friend's paintings "please us by their precision, each of them awakening a memory in our mind."Friedrich was acquainted with Philipp Otto Runge, another leading German painter of the Romantic period. He was also a friend of Georg Friedrich Kersting, and painted him at work in his unadorned studio, and of the Norwegian painter Johan Christian Clausen Dahl (17881857). Dahl was close to Friedrich during the artist's final years, and he expressed dismay that to the art-buying public, Friedrich's pictures were only "curiosities". While the poet Zhukovsky appreciated Friedrich's psychological themes, Dahl praised the descriptive quality of Friedrich's landscapes, commenting that "artists and connoisseurs saw in Friedrich's art only a kind of mystic, because they themselves were only looking out for the mystic... They did not see Friedrich's faithful and conscientious study of nature in everything he represented".During this period Friedrich frequently sketched memorial monuments and sculptures for mausoleums, reflecting his obsession with death and the afterlife; he even created designs for some of the funerary art in Dresden's cemeteries. Some of these works were lost in the fire that destroyed Munich's Glass Palace (1931) and later in the 1945 bombing of Dresden.
What is the full name of the person whose assistance toward the end of Friedrich's career proved invaluable to the ailing and impoverished artist?

Passage: Married competitive gamer couple Max and Annie are trying to have a child, but their attempts are unsuccessful due to Max's stress surrounding his feelings of inadequacy when compared to his successful, attractive brother Brooks. During Max and Annie's routine weekend game night with their friends Ryan, and married couple Kevin and Michelle, Brooks shows up Max by arriving in a Corvette Stingray (Max's dream car) and sharing an embarrassing childhood story about Max. Brooks offers to host the next game night at a house he is renting while he is in town. Meanwhile, Max and Annie are trying to keep their game nights secret from their neighbor Gary, an awkward police officer left distraught after his divorce from their friend Debbie.
When the guests, including Ryan's new date, Sarah, arrive at Brooks' house the following week, Brooks says he has initiated an interactive role-playing mystery game, promising the winner his Stingray. A man dressed as an FBI agent bursts into the home and informs them of the narrative of the mystery, only for two masked men to break in and assault him and Brooks. The guests believe the assault is part of the game. After Brooks is dragged out of the house, the couples begin to solve the mystery using the clues left behind by the actor.
Using his GPS location, Max and Annie track Brooks down to a seedy bar and, using a pistol left behind by Brooks during the struggle (which they believe to be fake), manage to take the keys to the storage closet, where Brooks is being held. After Annie mistakenly fires the gun and shoots Max in the arm, confirming the weapon is real and that they are in actual danger, the three escape. Brooks admits that he actually makes his living buying and selling illegal items on the black market, in particular a Faberge egg sought by a man known only as the Bulgarian and owned by a man using the alias Marlon Freeman. With his captors in pursuit, Brooks exits the moving car to guarantee Max and Annie's escape.
What are the first names of the people who are Debbie's friends?
