Question: When did the event where  Frank Alberry won a Distinguished Conduct Medal end? Passage:Frank Alberry, DCM (29 September 1892 – 23 January 1968) was an Australian soldier and airman who had a varied military career. Born in Hobart, he served in the Welch Regiment of the British Army before the First World War, but deserted. He joined up again in the early days of the First World War, and went on to serve with the 8th Battalion of the Australian Imperial Force. After service at Gallipoli, he joined the British Expeditionary Force in France. He won a Distinguished Conduct Medal at the Battle of Pozières, but lost a lower leg in the process. Alberry took the extraordinary step of personally petitioning King George V for permission to transfer to the Flying Corps, and subsequently became a flying ace credited with seven aerial victories. Alberry returned to service during the Second World War as a recruiter.

Question: In what era did the architectural style of Ince Blundell Hall emerge?  Passage:Ince Blundell Hall is in Georgian style. It is constructed in brick with sandstone dressings, and has an L-shaped plan. The main block faces southeast; it is in two storeys with an attic, and has a front of nine bays. Richard Pollard and Nikolaus Pevsner describe the front as being in late English Baroque style, and consider that it was "evidently inspired" by the front of Buckingham Palace, London. Between the upper storey and the attic is an entablature with a cornice and a panelled parapet. The central three bays project forward, the lower storeys are flanked by pairs of giant pilasters, and at the sides of the central doorway are giant columns. There are more pilasters at the ends of the building, and in the central three bays of the attic. All the pilasters and columns are Corinthian in style. The windows are sashes and are surrounded by architraves. The ground floor windows in the central bays have segmental heads with keystones, and those in the outer bays have friezes and pediments carried on consoles. Below the upper floor windows are panelled aprons and consoles. The central doorway has a segmental head and a keystone carved with the Blundell arms. At the corners of the front are quoins.
