Example Input: Question: When was the first college that Rollo May attended founded? Passage:May was born in Ada, Ohio, on April 21, 1909. He experienced a difficult childhood when his parents divorced and his sister was diagnosed with schizophrenia. He was the first son of a family with six children. His mother often left the children to care for themselves, and with his sister suffering from schizophrenia, he bore a great deal of responsibility. His educational career took him to Michigan State University, where he pursued a major in English, but he was expelled due to his involvement in a radical student magazine. After being asked to leave, he attended Oberlin College and received a bachelor's degree in English. He later spent three years teaching in Greece at Anatolia College. During this time, he studied with doctor and psychotherapist Alfred Adler, with whom his later work shares theoretical similarities. He became ordained as a minister shortly after coming back to the United States, but left the ministry after several years to pursue a degree in psychology. He was diagnosed with tuberculosis in 1942 and spent 18 months in a sanatorium. He later attended Union Theological Seminary for a BD during 1938, and finally to Teachers College, Columbia University for a PhD in clinical psychology in 1949. May was a founder and faculty member of Saybrook Graduate School and Research Center in San Francisco.

Example Input: Question: How long was Frank Pick the general manager? Passage:Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.
