Input: Question: How many islands comprise the nation that Lewis was born in? Passage:Lewis was born in Bermuda, the youngest of the three children – all boys – of Major Leonard Carey Lewis (1880–1952) and his wife, Katherine Barbara, née Sutton (1884–1965). There was a military tradition on both sides of the family, which the young Lewis did not follow: his musical talent became clear from his early years and he was sent to Salisbury Cathedral choir school, and at the age of eight he became a chorister at St George's Chapel, Windsor. At the age of 13 Lewis attended the Royal Academy of Music (RAM), London, studying composition with William Alwyn. He won a scholarship to Wellington College, from where, in 1932, he went to Peterhouse, Cambridge. There, according to The Times, he was "one of the most brilliant of his generation to have come under the influence of E.J.Dent". A scholarship enabled him to spend some months studying in Paris with Nadia Boulanger in 1934. He graduated the following year as BA and MusB.
