Task: Question Generation
Input (English): Passage: At the age of seventeen Lancaster passed his final school examinations and gained entrance to Lincoln College, Oxford, to study history. He persuaded his mother to allow him to leave Charterhouse at once, giving him several months between school and university, during which he enrolled on a course of life classes at the Byam Shaw School of Art in London. In October 1926 he started at Oxford. There, as at Charterhouse, he found two camps in which some students chose to group themselves: the "hearties" presented themselves as aggressively heterosexual and anti-intellectual; the "aesthetes" had a largely homosexual membership. Lancaster followed his elder contemporary Kenneth Clark in being contentedly heterosexual but nonetheless one of the aesthetes, and he was accepted as a leading member of their set. He cultivated the image of an Edwardian dandy, with large moustache, a monocle and check suits, modelling his persona to a considerable degree on Beerbohm, whom he admired greatly. He also absorbed some characteristics of the Oxford don Maurice Bowra; Lancaster's friend James Lees-Milne commented, "Bowra's influence over Osbert was marked, to the extent that he adopted the guru's booming voice, explosive emphasis of certain words and phrases, and habit in conversation of regaling his audiences with rehearsed witticisms and gossip." Lancaster's undergraduate set included Stephen Spender, Randolph Churchill, and most importantly John Betjeman, who became a close friend and lifelong influence.Lancaster tried rowing with the Oxford University Boat Club, but quickly discovered that he was no more suited to that than he had been to field games at school. He joined the Oxford University Dramatic Society (OUDS), acted in supporting roles, designed programme covers, wrote, and choreographed. He contributed prose and drawings to Isis and Cherwell magazines, engaged in student pranks, staged an exhibition of his pictures, attended life classes, and became established as a major figure in the Oxonian social scene. All these diversions led him to neglect his academic work. He had made things more difficult for himself by switching from the history course to English after his first year, a decision he regretted once confronted with the rigours of compulsory Anglo-Saxon, which he found incomprehensible. Making a belated effort, he extended his studies from the usual three years to four, and graduated with a fourth-class degree in 1930.
Output (English): What is the last name of the person that John Betjeman became a close friend and lifelong influence?
