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: 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.
[A]: Which types of boards have four holes where the binding threads were laced through?


[Q]: Passage: In early 2005, Frusciante entered the studio to work on his fifth and final studio album with the Chili Peppers, Stadium Arcadium. His guitar playing is dominant throughout the album, and he provides backing vocals on most of the tracks. Although usually following a "less is more" style of guitar playing, he began using a full twenty-four track mixer for maximum effect. In the arrangements, he incorporates a wide array of sounds and playing styles, similar to the funk-influenced Blood Sugar Sex Magik or the more melodic By the Way. He also changed his approach to his playing, opting to contribute solos and allow songs to be formed from jam sessions. In an interview from Guitar World, Frusciante explained how he approached his guitar solos for their album Stadium Arcadium completely differently from those for their previous albums. On Blood Sugar Sex Magik and Californication, Frusciante had a general idea how he wanted his guitar solos to sound. For Stadium Arcadium, almost every guitar solo was completely improvised by Frusciante on the spot. Several reviews have stressed that the influence of Hendrix is evident in his solos on the album, with Frusciante himself backing this up. He also expanded the use of guitar effects throughout the album, and used various other instruments such as the synthesizer and mellotron. He worked continuously with Rubin over-dubbing guitar progressions, changing harmonies and using all his technical resources.Frusciante began a series of collaborations with friend Omar Rodríguez-López and his band The Mars Volta, by contributing guitar and electronic instrumentation to song "Cicatriz ESP" off their album De-Loused in the Comatorium. He also contributed guitar solos on their 2005 album Frances the Mute. In 2006, he helped The Mars Volta complete their third album Amputechture by playing guitar on seven of its eight tracks. In return, Rodriguez-Lopez has played on several of Frusciante's solo albums, as well as making a guest appearance on Stadium Arcadium.
[A]: What is the name of the group that Frusciante provides backing vocals for?


[Q]: Passage: The Tower of London has become established as one of the most popular tourist attractions in the country. It has been a tourist attraction since at least the Elizabethan period, when it was one of the sights of London that foreign visitors wrote about. Its most popular attractions were the Royal Menagerie and displays of armour. The Crown Jewels also garner much interest, and have been on public display since 1669. The Tower steadily gained popularity with tourists through the 19th century, despite the opposition of the Duke of Wellington to visitors. Numbers became so high that by 1851 a purpose-built ticket office was erected. By the end of the century, over 500,000 were visiting the castle every year.Over the 18th and 19th centuries, the palatial buildings were slowly adapted for other uses and demolished. Only the Wakefield and St Thomas's Towers survived. The 18th century marked an increasing interest in England's medieval past. One of the effects was the emergence of Gothic Revival architecture. In the Tower's architecture, this was manifest when the New Horse Armoury was built in 1825 against the south face of the White Tower. It featured elements of Gothic Revival architecture such as battlements. Other buildings were remodelled to match the style and the Waterloo Barracks were described as "castellated Gothic of the 15th century". Between 1845 and 1885 institutions such as the Mint which had inhabited the castle for centuries moved to other sites; many of the post-medieval structures left vacant were demolished. In 1855, the War Office took over responsibility for manufacture and storage of weapons from the Ordnance Office, which was gradually phased out of the castle. At the same time, there was greater interest in the history of the Tower of London.Public interest was partly fuelled by contemporary writers, of whom the work of William Harrison Ainsworth was particularly influential. In The Tower of London: A Historical Romance he created a vivid image of underground torture chambers and devices for extracting confessions that stuck in the public imagination. Ainsworth also played another role in the Tower's history, as he suggested that Beauchamp Tower should be opened to the public so they could see the inscriptions of 16th- and 17th-century prisoners. Working on the suggestion, Anthony Salvin refurbished the tower and led a further programme for a comprehensive restoration at the behest of Prince Albert. Salvin was succeeded in the work by John Taylor. When a feature did not meet his expectations of medieval architecture Taylor would ruthlessly remove it; as a result, several important buildings within the castle were pulled down and in some cases post-medieval internal decoration removed.
[A]:
What is the full name of the person who suggested that Beauchamp Tower should be opened to the public?
