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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
Passage: Ghosts I–IV is the sixth studio album by American industrial rock band Nine Inch Nails, released on March 2, 2008 by The Null Corporation. It was the band's first independent release, following their split from longtime label Interscope Records the prior year. The album's production team included Nine Inch Nails frontman Trent Reznor, studio collaborators Atticus Ross and Alan Moulder, and instrumental contributions from Alessandro Cortini, Adrian Belew, and Brian Viglione.
Reznor described the music of Ghosts as "a soundtrack for daydreams", a sentiment echoed by critics, who compared it to the work of Brian Eno and Robert Fripp. The tracks are unnamed, identified only by their track listing and group number, and is an almost entirely instrumental album. Although initially intended to be a five-track EP, the final release consisted of four nine-track EPs, totaling 36 tracks. The album was released under a Creative Commons license (BY-NC-SA) and in a variety of differing packages and price points, including a US$300 "Ultra-Deluxe Limited Edition", without prior announcement. A user-generated "film festival" was also announced, inviting fans to visually interpret the music and post their submissions.
The album received a favorable reception from critics, who complimented its experimental nature and unorthodox release method, although some viewed the former as its weak point. The album reached number 14 in the US, and was nominated for two Grammy Awards (Best Rock Instrumental Performance and Best Box Set or Limited Edition Package) representing the first time music released under a Creative Commons license had been nominated for a Grammy Award.
Answer:
What was the full name of the album that was compared to the works of Brian Eno and Robert Fripp?
