Task: Question Answering
Input (English): Passage: Edmund Sharpe was born on 31 October 1809 at Brook Cottage, Brook Street in Knutsford, Cheshire, the first child of Francis and Martha Sharpe.  His father, a peripatetic music teacher and organist at Knutsford parish church, came from Stamford in Lincolnshire.  At the time of marriage his wife, Martha Whittaker, was on the staff of an academy for young ladies, Belvedere House, in Bath, Somerset. During his childhood in Knutsford, the young Edmund played with Elizabeth Stevenson, the future Mrs Gaskell. In 1812 the Sharpe family moved across town from Over Knutsford to a farm in Nether Knutsford called Heathside, when Francis Sharpe then worked as both farmer and music teacher.  Edmund was initially educated by his parents, but by 1818 he was attending a school in Knutsford.  Two years later he was a boarder at a school near Runcorn, and in 1821 at Burney's Academy in Greenwich. Edmund's father died suddenly in November 1823, aged 48, and his mother moved to Lancaster with her family, where she later resumed her teaching career.Edmund continued his education at Burney's Academy, and became head boy. In August 1827 he moved to Sedbergh School (then in the West Riding of Yorkshire, now in Cumbria), where he remained for two years. In November 1829 he entered St John's College, Cambridge as a Lupton scholar. At the end of his course in 1832 he was awarded a Worts Travelling Bachelorship by the University of Cambridge, which enabled him to travel abroad for three years' study.  At this time his friend from Lancaster at Trinity College, William Whewell, was Professor of Mineralogy. John Hughes, Edmund Sharpe's biographer, is of the opinion that Whewell was influential in gaining this award for Sharpe. Edmund graduated BA in 1833, and was admitted to the degree of MA in 1836. During his time abroad he travelled in Germany and southern France, studying Romanesque and early Gothic architecture. He had intended to travel further into northern France, but his tour was curtailed in Paris owing to "fatigue and illness". Edmund returned home to Lancaster late in 1835, having by then decided to become an architect. In December he wrote a letter to William Whewell saying that he had "finally determined to adopt the Profession of Architecture".  Some sources state that Sharpe was articled to the architect Thomas Rickman. Sharpe did visit Rickman for a few days in 1832 and corresponded with him later. He may have been "acting as a research assistant" while on the Continent, but Hughes states "there is no evidence to suggest that Sharpe spent more time with Rickman, or served any kind of formal apprenticeship with him".
