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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many commisions of Sydney Mandolins have their been?
Ah, so.. over 200 works

The surface bedrock under the Miami area is called Miami oolite or Miami limestone. This bedrock is covered by a thin layer of soil, and is no more than 50 feet (15 m) thick. Miami limestone formed as the result of the drastic changes in sea level associated with recent glaciations or ice ages. Beginning some 130,000 years ago the Sangamonian Stage raised sea levels to approximately 25 feet (8 m) above the current level. All of southern Florida was covered by a shallow sea. Several parallel lines of reef formed along the edge of the submerged Florida plateau, stretching from the present Miami area to what is now the Dry Tortugas. The area behind this reef line was in effect a large lagoon, and the Miami limestone formed throughout the area from the deposition of oolites and the shells of bryozoans. Starting about 100,000 years ago the Wisconsin glaciation began lowering sea levels, exposing the floor of the lagoon. By 15,000 years ago, the sea level had dropped to 300 to 350 feet (90 to 110 m) below the contemporary level. The sea level rose quickly after that, stabilizing at the current level about 4000 years ago, leaving the mainland of South Florida just above sea level.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is another name for Miami limestone?
Ah, so.. Miami oolite

Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?] and has conducted several research studies in order to find methods of combating fatigue in pilots.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who follows a very natural human circadian rhythem?
Ah, so..
