Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: What are the names of the La Quinta Esencia hit singles? Passage:Self-titled debut album WarCry was released on April 17, 2002. Guitarists Pablo García and Fernando Mon appeared only as guest musicians on the debut album, but became full-time members on 2002 along with keyboardist Manuel Ramil and bassist Alvaro Jardón. Second album El Sello De Los Tiempos was released on December 1, 2002. At the end of 2003, Jardón left the band due to musical and personal issues. On January 1, 2004 was released the third album Alea Jacta Est striking all the music stores around Spain. On the first concert of the tour supporting the album, the band presented Roberto García, formerly of Avalanch, as Jardón's replacement. Their fourth studio album, ¿Dónde Está La Luz?, was released on February 1, 2005, considered by critics "their heaviest album to date". They embarked on a supporting tour throughout Spain. WarCry played a sold-concert in Madrid. That performance was released on February 27, 2006 as a live album, named Directo A La Luz and soon was certified gold. La Quinta Esencia was their fifth album, released on September 18, 2006 with a great acceptance by the fans and the press, taking them to the highest positions on the Spanish charts. Sixth album was set to be released on May/June, 2008, but after the lineup changes they pushed it back to September, 2008. Víctor García stated that "this album will express much duality in human beings — good and evil."

Question: Who was the founder of the school where Constant Mews studied for his doctorate? Passage:Mews attended the University of Auckland and completed BA and MA degrees there in History. He carried out doctoral study at the University of Oxford, followed by five years (1980–1985) teaching British civilisation at the Universite de Paris III, while pursuing studies in medieval thought (focusing on Peter Abelard) in connection with Jean Jolivet, at the École pratique des hautes études en sciences religieuses. This was followed by two years as a Leverhulme research fellow at the University of Sheffield on editing the writings of Peter Abelard. Mews took up a position at Monash University as Lecturer in the Department of History in July 1987. He became involved in developing the Centre for Studies in Religion and Theology and in promoting studies in religion more generally, with a strong interest in interfaith work. He has had spells of study at the Institute for Advanced Study, Princeton, in 1990 and 2000, and has also again taught in Paris, at the École pratique des hautes études (Ve section) and in the École des hautes études en sciences sociales.

Question: How long had Les Paul guitars been made by Gibson? Passage:Old Black is a 1953 Gibson Les Paul Goldtop, painted black and customized considerably. After the guitar had been left at a guitar repair store, the original P-90 bridge pickup was replaced with a Gretsch Dynasonic single-coil pickup. Eventually, a mini humbucker pickup from a Gibson Firebird guitar replaced the Dynasonic. The neck pickup has always been the original P-90 pickup, but it is now covered by a hand fitted aluminum P-90 cover, replacing the original white plastic cover. The guitar was roughly resprayed to jet black, and received a new Tune-o-matic bridge (not available when the guitar was produced) and a B-7 model Bigsby vibrato tailpiece. It would presumably also have had a white plastic pickguard at some point, as was standard on 1953 Goldtops. Old Black is notable for its metal hardware, including aluminum backing plates. The pick guard is chrome-on-brass/bronze. The tuners have been replaced with Schaller M-6 tuning keys, and the rest of the hardware is mostly nickel-plated. The headstock displays a partially painted-over mother-of-pearl inlay, sometimes referred to as a "wheat stack", rather than the typical silk screened "Les Paul Model" logo, along with single-ply binding around the headstock, although the binding has now fallen off.
