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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Example solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Problem: Passage: Drummond and Cauty's works were both highly self-referential and rife with references to The Illuminatus! Trilogy esoteric novel, from which The JAMs took their name. Their last work, as 2K and K2 Plant Hire, continued many of these themes. Their subversive attitude was exhibited in their attempt to undermine the pop comeback. They defaced a wall of the National Theatre the day after the Barbican performance: the graffiti "1997: What the fuck's going on?" referenced their similar graffiti of ten years earlier on the same wall of the arts establishment. The unusual show at the Barbican was typical of their previous confusing and humorous costumed appearances; moreover, the horns strapped to their foreheads were previously used in The KLF's cowl costumes. The advertising campaigns before and after the single's release resumed Drummond and Cauty's characteristic promotional tactic of cryptic, monochrome full-page adverts placed in UK national newspapers and music press.
The duo's tenth anniversary was prominently implied by the adverts and graffiti, and "Fuck the Millennium" contains many samples from their earliest works. The KLF's "What Time Is Love?"a breakthrough track for Drummond and Cauty on two occasionsis also used extensively: "Fuck the Millennium" contains the entirety of "What Time Is Love? (Pure Trance Original)", as well as samples used in "What Time Is Love? (Live at Trancentral)".
Seafaring was a recurring element of Drummond and Cauty's output, in lyrics from Who Killed The JAMs?, The White Room and "America: What Time Is Love?", and in imagery used to illustrate The KLF's retirement press notice. Prior to entering the music business, Drummond had worked as a trawlerman. Samples of evangelists also feature in several KLF Communications recordings: the album Chill Out and the B-sides "What Time Is Love? (Virtual Reality Mix)" and "America No More". "Fuck the Millennium" was a studio track promoted as a live recording and featuring sampled crowd noise, as were The KLF's self-named "Stadium House Trilogy" of singles. The use of an English hymn is central to The JAMs' "It's Grim up North". All of The KLF's chart singles either refer or allude to time, a theme continued by "Fuck the Millennium".
2K's lifespan was billed as the duration of the Barbican performance, 23 minutes. The number is given numerological significance in The Illuminatus! Trilogy. The "Fuck the Millennium" sleevenotes state that "The Justified Ancients of Mu Mu appear courtesy of The Five", a reference to the five Illuminati leaders of the novels. Drummond and Cauty took The JAMs' name from the fictional cult in Illuminatus!, wherein the fictional JAMs are long-standing enemies of the Illuminati. K2 Plant Hire's "The People's Pyramid" recalled Drummond and Cauty's "Pyramid Blaster" logo (a ghetto blaster suspended in front of a pyramid), itself a reference to the all-seeing eye icon used in Illuminatus!.
Solution: What is the name of the group whose tenth anniversary was prominently implied by the adverts and graffiti?
