Input: Question: In what year was the last Clone Saga book published? Passage 1:After his school-leaving examination (Abitur) at the secondary school Antonianum in Vechta Ludger Gerdes studied at the Academy of Arts in Münster with Timm Ulrichs and Lothar Baumgarten from 1975 to 1977, and from 1977 to 1982 at the Düsseldorf Academy of Arts with Gerhard Richter. At the beginning of the 1980s Gerdes stood out in exhibitions and actions with his criticism of the link between modern art, the museum and the temporary exhibition. At this time he exhibited among others along with Thomas Schütte. He pleaded for works of art as a means for the organization of public space and as a medium of communication. The English landscape garden was a particularly important historical model of this to him. At this time he was regarded as the intellectual head of the artist-group of Düsseldorf pattern makers (Düsseldorfer Modellbauer). In 1982 he was included in the documenta 7 in Kassel. He became known to a larger public in 1987 with his land art project A Ship for Münster (Ein Schiff für Münster) for the show "Skulptur.Projekte" in Münster. From 1990 to 1992 he taught at the Städelschule, Frankfurt; from 1998 to 2004 he was professor for painting and multimedia at the art academy in Karlsruhe; since 2005 he was professor for painting at the Muthesius Art Academy in Kiel. Parallel to his professorship he lived and worked as an artist in Munich and Düsseldorf.
 Passage 2:Born in Eccleshall, Staffordshire, Hibbert started his career at League One Port Vale, rising through the ranks from the age nine years old. He made three starts and seven substitute appearances in first season with Vale; and his promising maiden season was restricted only by a head injury sustained at Milton Keynes Dons. His two goals for the club both came in his second starting appearance in a 3–1 win over Luton Town on 26 February 2005. In June 2005 Championship side Preston North End signed him to a contract. As Hibbert was under the age of 23, the fee was decided by a tribunal according to UEFA regulations. Preston were ordered to pay Port Vale £35,000 up front with add ons of £10,000 for each 10 of his first 50 appearances for Preston (Vale would only receive the first of these due to him only making 13 appearances in total for Preston); a £280,000 bonus if Preston achieved promotion to the Premiership; plus a 25% sell-on clause if Hibbert was sold on. Vale chairman Bill Bratt was highly disappointed with the news and stated: "I believe he has potential, and he is worth a lot more than we have ended up with." Meanwhile, Preston manager Billy Davies stated that: "We are very fortunate to get this young lad because there were several clubs interested. We think his finishing is very good and – like David Nugent – he is very quick, but to be honest I think he is quite a way from first-team action."
 Passage 3:Kavanagh was a Marvel Comics editor from 1985 to 1997. Titles he edited during that time included Marvel Comics Presents and Nick Fury, Agent of S.H.I.E.L.D. Writer/artist Alan Davis, who Kavanagh edited on Excalibur, said "Terry Kavanagh spoiled me, gave me near total freedom, and encouraged me to experiment." In 1987, he began to write for Marvel with his first published story "Cry Vengeance!" appearing in Kickers, Inc. #4 (Feb. 1987). He later wrote such titles as Marc Spector: Moon Knight, Avengers: Timeslide, X-Man and X-Universe. In Web of Spider-Man #100 (May 1993), Kavanagh and artist Alex Saviuk gave the lead character "Spider-Armor". He wrote the Spider-Man/Punisher/Sabretooth: Designer Genes one-shot the following month. Kavanagh was one of the writers on the "Maximum Carnage" storyline which ran through the various Spider-Man titles in 1993. The first Black Cat limited series was co-written by Kavanagh and Joey Cavalieri in 1994. Kavanagh pitched a storyline involving the return of Spider-Man's clone, which then formed the basis of the "Clone Saga" which began in Web of Spider-Man #117 (Oct. 1994). Kavanagh's last new comics project was the Before the Fantastic Four: The Storms limited series in 2000–2001.
