[Q]: Passage: Selenizza is a naturally occurring solid hydrocarbon bitumen found in the native asphalt deposit of Selenice, in Albania, the only European asphalt mine still in use. The rock asphalt is found in the form of veins, filling cracks in a more or less horizontal direction. The bitumen content varies from 83% to 92% (soluble in carbon disulphide), with a penetration value near to zero and a softening point (ring & ball) around 120 °C. The insoluble matter, consisting mainly of silica ore, ranges from 8% to 17%.
[A]: The soluble matter consists mainly of silica ore and ranges from what percentage?


[Q]: Passage: Many sports popular today were formalised by British Public schools and universities in the 19th century. These schools produced the civil servants and military and naval officers required to build and maintain the British empire, and team sports were considered a vital tool for training their students to think and act as part of a team. Former public schoolboys continued to pursue these activities, and founded organisations such as the Football Association (FA). Today's association of football with the working classes began in 1885 when the FA changed its rules to allow professional players.
[A]:
What does AF stand for?
