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.

[Q]: 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.
[A]: What is the full name of the person who fails to impress Kurt Bergner?


[Q]: Passage: In 1988, Harrison formed the Traveling Wilburys with Jeff Lynne, Roy Orbison, Bob Dylan and Tom Petty. The band had gathered in Dylan's garage to record a song for a Harrison European single release. Harrison's record company decided the track, "Handle with Care", was too good for its original purpose as a B-side and asked for a full album. The LP, Traveling Wilburys Vol. 1, was released in October 1988 and recorded under pseudonyms as half-brothers, supposed sons of Charles Truscott Wilbury, Sr. It reached number 16 in the UK and number 3 in the US, where it was certified triple platinum. Harrison's pseudonym on the album was "Nelson Wilbury"; he used the name "Spike Wilbury" for their second album.In 1989, Harrison and Starr appeared in the music video for Petty's song "I Won't Back Down". In October that year, Harrison assembled and released Best of Dark Horse 1976–1989, a compilation of his later solo work. The album included three new songs, including "Cheer Down", which Harrison had recently contributed to the Lethal Weapon 2 film soundtrack.Following Orbison's death in December 1988, the Wilburys recorded as a four-piece. Their second album, issued in October 1990, was mischievously titled Traveling Wilburys Vol. 3. According to Lynne, "That was George's idea. He said, 'Let's confuse the buggers.'" It peaked at number 14 in the UK and number 11 in the US, where it was certified platinum. The Wilburys never performed live, and the group did not record together again following the release of their second album.In December 1991, Harrison joined Clapton for a tour of Japan. It was Harrison's first since 1974 and no others followed. On 6 April 1992, Harrison held a benefit concert for the Natural Law Party at the Royal Albert Hall, his first London performance since the Beatles' 1969 rooftop concert. In October 1992, he performed at a Bob Dylan tribute concert at Madison Square Garden in New York City, playing alongside Dylan, Clapton, McGuinn, Petty and Neil Young.
