Problem: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish. For over 30 years the National Archives have forbidden flash photography but the advent of cameras with automatic flashes have made the rules increasingly difficult to enforce. As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.
For how long has the National Archives prohibited flash photography?

Answer: over 30 years


Problem: The Sydney Mandolins (Artistic Director: Adrian Hooper) have contributed greatly to the repertoire through commissioning over 200 works by Australian and International composers. Most of these works have been released on Compact Disks and can regularly be heard on radio stations on the ABC and MBS networks. One of their members, mandolin virtuoso Paul Hooper, has had a number of Concertos written for him by composers such as Eric Gross. He has performed and recorded these works with the Sydney Symphony Orchestra and the Tasmanian Symphony Orchestra. As well, Paul Hooper has had many solo works dedicated to him by Australian composers e.g., Caroline Szeto, Ian Shanahan, Larry Sitsky and Michael Smetanin.

Problem: The Diwan of Umar, assigning annuities to all Arabs and to the Muslim soldiers of other races, underwent a change in the hands of the Umayyads. The Umayyads meddled with the register and the recipients regarded pensions as the subsistence allowance even without being in active service. Hisham reformed it and paid only to those who participated in battle. On the pattern of the Byzantine system the Umayyads reformed their army organization in general and divided it into five corps: the centre, two wings, vanguards and rearguards, following the same formation while on march or on a battle field. Marwan II (740–50) abandoned the old division and introduced Kurdus (cohort), a small compact body. The Umayyad troops were divided into three divisions: infantry, cavalry and artillery. Arab troops were dressed and armed in Greek fashion. The Umayyad cavalry used plain and round saddles. The artillery used arradah (ballista), manjaniq (the mangonel) and dabbabah or kabsh (the battering ram). The heavy engines, siege machines and baggage were carried on camels behind the army.
Along with artillery and infantry, what was the third division of Umayyad troops under Marwan II?
