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: A remix album, titled Year Zero Remixed, was released in November 2007. Due to the expiration of his contract with Interscope Records, the album's release, marketing, and promotion were completely in Reznor's control. The album features remixes from artists including The Faint, Ladytron, Bill Laswell, Saul Williams, Olof Dreijer of The Knife, and Sam Fogarino of Interpol. Reznor himself strongly supports fan-made remixes of songs from the album, as evidenced by his decision to upload every song in multi-track form to the then-newly launched Nine Inch Nails remix website.  Instrumental versions of the songs on Year Zero are available at the site for download in multiple formats, including MP3, WAV, GarageBand, and Ableton Live formats.
A planned film adaption of Year Zero became a television project in 2007. Reznor met with various writers and pitched the idea to television networks. The 2007–08 Writers Guild of America strike affected the pre-production stage. Nevertheless, Reznor commented in 2008 that the project is "still churning along", and that he had begun working with American film producer Lawrence Bender. In 2010, Reznor started developing the Year Zero miniseries with HBO and BBC Worldwide Productions. Reznor and Bender collaborated with Carnivàle writer Daniel Knauf to create the science fiction epic. When asked about the miniseries during an "Ask Me Anything" session on Reddit on November 13, 2012, Reznor said it was "currently in a holding state" and explained, "We [Reznor and Sheridan] didn't find the right match with a writer, and really have been avoiding doing what we should have done from the beginning: write it ourselves. [...] This project means a lot to me and will see the light of day in one form or another." In 2017, during an interview promoting new Nine Inch Nails EP Add Violence, Reznor said that "They got so far as hiring a writer for it, but then it fell to shit because we never had the right writer. I should have just done it [myself].".

Q: Passage: Fifteen-year-old Ellis Whitman is leaving his home in Tucson, Arizona, for his freshman year at Gates Academy, an East Coast prep school. He leaves behind Wendy, his flaky, New Age mother and Goat Man, a weed-smoking goat trekker and botanist. Goat Man is the only real father  Ellis has ever known, since his biological father, Frank, left when he was a baby.
Upon arriving Gates Academy, Ellis befriends his roommate Barney Cannel, a cross-country runner, and Rosenberg, who usually does not get anything higher than a C in his classes, but is smart enough to sneak in marijuana. Ellis also takes an interest in Minnie, a local girl who works in the school library; his friends often refer to her as a prostitute, according to rumors. Meanwhile, Goat Man and Wendy have been incommunicado, which Barney points out often. On a phone call, Ellis discovers that his mother has a new boyfriend named Bennet, who is rude and disrespectful.
One day, Ellis receives a letter in the mail from his long-estranged father from Washington, DC, requesting for Ellis to spend Thanksgiving dinner with him. Ellis decides to fly to Washington with Barney, who is also having Thanksgiving with his mother there. Ellis finally meets his father and his father's pregnant and kind-hearted wife, Judy. One night, Ellis gets a call from Barney telling him that he is in possession of marijuana. Ellis sneaks out for the night, but Frank finds out that he left. On the way back from his flight from DC, Barney and Ellis get drunk and fight with each other in their dorm room, resulting in a dent in the wall which costs Wendy $700 and Ellis to end up in the school hospital. Afterwards, Ellis begins to get closer to Minnie.

Q: Passage: Four battalions of rebel troops moved before dawn from the Mekong Delta towards Saigon, using armored personnel carriers and jeeps carrying machine guns. After cowing several police checkpoints on the edge of the capital with threats of machine-gun and artillery fire, the plotters put rebel sentries in their place to seal off Saigon from incoming or outgoing traffic. They then captured communication facilities in the capital, including the post office, to prevent messages from being sent in or out. As his troops took over the city, Phát sat in a civilian vehicle and placidly said "We'll be holding a press conference in town this afternoon at 4 p.m." He said "This is nothing to worry about. Just a little operation against some politicians." The rebels set up their command post in the Saigon home of General Duong Ngoc Lam, who had been removed from his post as Mayor of Saigon by Khánh. Lam had commanded the Civil Guard during Diệm's presidency and was one of his trusted supporters.The rebels took over the city without any gunfire, and used the national radio station to make a broadcast. Claiming to represent "The Council for the Liberation of the Nation", Phát proclaimed a regime change, and accused Khánh of promoting conflict within the nation's military and political leadership. He promised to capture Khánh and pursue a policy of increased anti-communism, with a stronger government and military. Phát said he would use the ideology and legacy of Diệm to lay the foundation for his new junta. Đức claimed the coup attempt was prompted by "the transfer to the capital of some neutralist elements, and by some pro-communists in the government". According to the historian George McTurnan Kahin, Phát's broadcast was "triumphant" and may have prompted senior officers who were neither part of the original conspiracy nor fully loyal to Khánh to conclude that Phát and Đức would not embrace them if they abandoned Khánh.In contrast to Phát's serene demeanor, his incoming troops prompted devotees at the Catholic cathedral—who were attending mass—to run away in fear. The Buddhists however, made no overt reaction to the pro-Diệm coup, even though the former president had pursued policies that discriminated against them. There was little reaction from most of the military commanders. The Republic of Vietnam Air Force commander Air Marshal Nguyễn Cao Kỳ had promised a fortnight earlier to use his aircraft against any coup attempt, but he took no action early in the morning. At the same time, Khiêm and Thieu's lack of public action was seen as implicit support for the coup, as their criticism of Khánh's leadership in junta meetings and private attempts to remove him were well-known. A US Embassy report to the State Department during the coup described Thieu and Khiêm as being "so passive that they appear to have been either tacitly supporting or associated with this move by Đức and Phát".
