Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children.

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.
