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: The Smashing Pumpkins' distinctive sound up until Adore involved layering numerous guitar tracks onto a song during the recording process, a tactic that Mellon Collie and the Infinite Sadness coproducer Flood called the "Pumpkin guitar overdub army." Although there were a lot of overdubbed parts on Gish, Corgan began to really explore the possibilities of overdubbing with Siamese Dream; Corgan has stated that "Soma" alone contains up to 40 overdubbed guitar parts. While Corgan knew many of the songs would be difficult or impossible to replicate from their recorded versions in concert (in fact, some songs were drastically altered for live performance), he has explained the use of overdubbing by posing the question "When you are faced with making a permanent recorded representation of a song, why not endow it with the grandest possible vision?" This use of multilayered sounds was inspired by Corgan's love of 1970s popular artists & bands such as: David Bowie, Cheap Trick, Queen, Boston, and the Electric Light Orchestra, as well as shoegaze, a British alternative rock style of the late 1980s and early 1990s that relied on swirling layers of guitar noise for effect. Mellon Collie coproducer Alan Moulder was originally hired to mix Siamese Dream because Corgan was a fan of his work producing shoegaze bands such as My Bloody Valentine, Ride, and Slowdive.Like many contemporary alternative bands, the Smashing Pumpkins utilized shifts in song dynamics, going from quiet to loud and vice versa. Husker Du's seminal album Zen Arcade demonstrated to the band how they could place gentler material against more aggressive fare, and Corgan made such shifts in dynamics central to the pursuit of his grand musical ambitions. Corgan said he liked the idea of creating his own alternative universe through sound that essentially tells the listener, "Welcome to Pumpkin Land, this is what it sounds like on Planet Pumpkin." This emphasis on atmosphere carried through to Adore (described as "arcane night music" in prerelease promotion) and the Machina albums (concept records that tell the story of a fictional rock band).
Solution: Whose album did Flood co-produce?
