Teacher: Now, understand the problem? Solve this instance: Passage: Curtis was born at Coddington, Herefordshire in 1872, the youngest of the four children of an Anglican rector. He was educated at Haileybury College and then at New College, Oxford, where he read law. He fought in the Second Boer War with the City Imperial Volunteers and served as secretary to Lord Milner (a position that had also been held by adventure-novelist John Buchan), during which time he dedicated himself to working for a united self-governing South Africa. Following Milner's death in 1925, he became the second leader of Milner's Kindergarten until his own death in 1955. His experience led him to conceptualize his version of a Federal World Government, which became his life work. In pursuit of this goal, he founded (1910) the quarterly Round Table. He was appointed (1912) Beit lecturer in colonial history at the University of Oxford, and a Fellow of All Souls College.
