PROBLEM: Passage: The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.

PROBLEM: Passage: McGeoch was born on October 9, 1897 in Argyle, New York. He received his bachelor's degree from Westminster College in 1918, and a master's degree from Colorado College in 1919. His master's thesis, titled "The Present Status of Psychology", is a review of the history of the field of psychology and how the role of psychology was viewed in the early 20th century. He then studied under Harvey A. Carr at the University of Chicago. He studied a variety of topics while at the University of Chicago, including suggestibility and intelligence in delinquents, time perception, neuropsychological and vocational testing, and the reliability and validity of the Pressey X-O test. His doctoral dissertation was titled "A study in the psychology of testimony." Following the completion of his dissertation, McGeoch’s work primarily focused on human learning and memory. Harvey Carr significantly influenced McGeoch’s work, and provided feedback on the McGeoch's introductory textbook on human learning, The Psychology of Human Learning, which was published after Carr’s death in 1943. McGeoch completed his PhD while he was a faculty member at the University of Washington. He accepted a full Professor position 2 years later at the University of Arkansas. In 1930 he moved to the University of Missouri where he became the chair of the department of psychology. He held this position for 5 years before moving to Wesleyan University, where he was also chair of the department from 1935–1939 and was awarded an honorary degree in recognition of his accomplishments as a lecturer and administrator. In 1939, McGeoch moved to the University of Iowa, where he also chaired the department. He died in Iowa City on March 3, 1942 from a cerebral hemorrhage.
 Link Information:  Carr was driven to learn more.

At the age of 18, Carr became a student of DePauw University's preparatory department. He was able to complete a three-year course in two years by taking extra classes and performing extra work in a district school.  Question: From what university did the person McGeoch studied under at the University of Chicago graduate?

SOLUTION: Answer: DePauw University

PROBLEM: Passage: Hynde, originally from Akron, Ohio, moved to London in 1973, working at the weekly music paper NME and at Malcolm McLaren and Vivienne Westwood's clothes store. She was involved with early versions of the Clash and the Damned and played in short-lived bands such as Masters of the Backside (1976) and the Moors Murderers (1978 lineup). The Pretenders formed in 1978 after Dave Hill at Anchor Records heard some demos of Hynde's music. He arranged a rehearsal studio in Denmark Street, where a three-piece band consisting of Hynde, Mal Hart on bass (he had played with Hynde and Steve Strange in the Moors Murderers), and Phil Taylor of Motörhead on drums played a selection of Hynde's original songs. Dave Hill was impressed and arranged a day at Studio 51 to record another demo. Although it was rough, he felt he had seen and heard enough "star potential" to suggest that Hynde form a more permanent band to record for his new label, Real Records. Hynde then formed a band composed of Pete Farndon on bass, James Honeyman-Scott on guitar, and Gerry Mcilduff on drums. This band, then without a name, recorded five tracks at Regents Park Studio in July 1978, including "Stop Your Sobbing". Shortly thereafter, Gerry Mcilduff was replaced on drums by Martin Chambers. Hynde named the band "The Pretenders" after the Platters song "The Great Pretender", which was the favourite song of one of her former boyfriends.
 Link Information: The band is only known to have performed once, before a small invited audience in a church hall in Lisson Grove, London. Question: How long did the Masters of the Backside exist as a band?

SOLUTION:
Answer: 1
