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.

Input: Consider Input: Passage: The boards of the covers, previously assumed to be limewood, are now thought to be birch, an unusual wood in later bindings, but one easily available in northern England.  Both have four holes where the binding threads were laced through; the two threads were run round the inner edges of the cover and knotted back at the holes.  The front cover has an additional 12 holes where the ends of the cords for the raised framing lines went through, at the four corners of the two main frames, and the ends of the horizontal bars between the interlace panels and the central vine motif.The stitching of the binding uses "Coptic sewing", that is "flexible unsupported sewing (produced by two needles and thread looping round one another in a figure-of-eight sewing pattern)"  Coptic sewing uses small threads both to attach the leaves together and, knotted together, to attach the pages to the cover boards. Normal Western binding uses thread for the former and thicker cord running across the spine of the book for the latter, with the thread knotted onto the cords.  Coptic sewing is also found in the earliest surviving leather bookbindings, which are from Coptic libraries in Egypt from the 7th and 8th centuries; in particular the design of the cover of one in the Morgan Library (MS M.569) has been compared to the St Cuthbert Gospel.  In the techniques used in the binding, apart from the raised decoration, the closest resemblance is to an even smaller Irish pocket gospel book from some 50 years later, the Cadmug Gospels at Fulda, which is believed to have belonged to Saint Boniface.  This is also in red goatskin, with coloured incised lines, and uses a similar unsupported or cordless stitching technique.  The first appearance of the cords or supports that these "unsupported" bindings lack is found in two other books at Fulda, and they soon became universal in, and characteristic of, Western bookbinding until the arrival of modern machine techniques.  The cords run horizontally across the spine, and are thicker than the threads that hold the pages together.  They are attached, typically by lacing through holes or glue, to the two boards of the cover, and the threads holding the gatherings are knotted to them, resulting in a stronger binding.

Output: Which types of boards have four holes where the binding threads were laced through?


Input: Consider Input: Passage: Doug is a flight instructor and owner of a pilot school. He, his wife Abby and their two daughters, Lindsay and Amanda face serious financial problems, as they are near financial ruin, and need $300,000 to expand the pilot school. 
Doug has to work hard and has hardly any time for his family, even arriving at home late on Christmas Eve. During the meal Doug receives a phone call from a lawyer who informs him that his parents are not his biological parents, but that he was adopted by an open adoption by them. The lawyer asks him to come to a meeting, where problems concerning his biological father are to be discussed.
The lawyer introduces him to his half sister, Delilah, who was disowned from their father. Her only interest is to have her father judged unfit in order to sell his property. The lawyer asks whether they want to look after the property and their father. If they would, they would also take responsibility of him. Doug decides to do so without asking Abby.

Output: What are the first names of the family that is facing serious financial problems?


Input: Consider Input: Passage: In support of Nine Inch Nails' third full-length studio album, The Fragile, the live-band reformed for the Fragility tour.  The lineup remained largely the same from the Self-Destruct tour, featuring Finck, Clouser, and Lohner.  To replace long-time member Vrenna, Reznor held open auditions to find a new drummer, eventually picking then-unknown Jerome Dillon.  Dillon would remain a member of the live band until 2005.
Nine Inch Nails' record label at the time, Interscope Records, reportedly refused to fund the promotional tour following The Fragile's lukewarm sales.  Reznor instead committed himself to fund the entire tour out of his own pocket, concluding that "The reality is, I’m broke at the end of the tour," but also adding "I will never present a show that isn’t fantastic."The Fragility tour began in late 1999, running until mid-2000, and was broken into two major legs, Fragility 1.0 and Fragility 2.0 respectively.  Destinations included Europe, Japan, New Zealand, Australia, and North America.  Before the first Fragility performance date in Spain, Nine Inch Nails opened their final rehearsal in London to 100 fans. Kick-starting the tour was a performance of the title track from The Fragile at the MTV Video Music Awards.  Atari Teenage Riot opened for Nine Inch Nails during Fragility 1.0, and A Perfect Circle for Fragility 2.0.  At the time, A Perfect Circle featured Josh Freese on drums, who would later replace Dillon and play drums for Nine Inch Nails from 2005 to 2007. The tour featured increasingly large production values, including a triptych video display created by contemporary video artist Bill Viola. Rolling Stone magazine named Fragility the best tour of 2000.In 2002, the tour documentary And All That Could Have Been was released featuring a collection of performances from the Fragility 2.0 tour.  While making the DVD, Reznor commented on the tour in retrospect by saying "I thought the show was really, really good when we were doing it", but later admitted that he "can't watch [the DVD] at all. I was sick for most of that tour and I really don't think it was Nine Inch Nails at its best".


Output: What was the name of the drummer on the Self-Destruct tour?
