Example Input: 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.

Example Input: Question: How many years after its creation did the Far East Air Forces move to Hawaii? Passage:After World War II, the Air Force in Hawaii consisted primarily of the Air Transport Command and its successor, the Military Air Transport Service (MATS), until 1 July 1957 when Headquarters Far East Air Forces completed its move from Japan to Hawai‘i and was redesignated the Pacific Air Forces (PACAF). The 15th Air Base Wing, host unit at Hickam AFB, supported the Apollo astronauts in the 1960s and 1970s; Operation Homecoming (return of prisoners of war from Vietnam) in 1973; Operation Babylift / New Life (movement of nearly 94,000 orphans, refugees, and evacuees from Southeast Asia) in 1975; and NASA's space shuttle flights in the 1980s and 1990s. Hickam is home to the 65th Airlift Squadron which transports theater senior military leaders throughout the world in the C-37B and C-40 Clipper aircraft. In mid-2003, the 15th Air Base Wing (15 ABW) was converted to the 15th Airlift Wing (15 AW) as it prepared to beddown and fly the Air Force's newest transport aircraft, the C-17 Globemaster III.
