[Q]: Two female members of this occupation served under John Rackham and were named Mary Read and Anne Bonny. Members of this profession could gain government support if granted a Letter of Marque, which made them privateers. In this occupation's Golden Age, Bartholomew Roberts had the most success, and that age also saw the likes of (*) Edward Teach and William Kidd. For 10 points, name this profession that got the majority of its members from the ships it robbed, and whose captains included Blackbeard and whose ships flew the Jolly Roger.
[A]: History

[Q]: In 1997 Edwin Hall wrote a book about this work which discussed the inclusion of St. Margaret emerging from the belly of a dragon, which can be seen carved above the back of a chair, to argue that Erwin Panofsky's influential interpretations are too simplistic. Commissioned by its subject, a counselor to the Duke of Burgundy who made his money as a silk merchant, the year and the artist's signature can be seen above the mirror whose reflection depicts the artist himself. That artist would go on to paint other famous portraits like The Madonna with the Chancellor Rolin. Filled with details like a lit candle, a little dog, and a pair of discarded clogs, FTP, identify this work that depicts a man dressed in dark heavy wool and a big hat holding the hand of his betrothed, a painting by Jan van Eyck.
[A]: Fine Arts

[Q]: The diffusion coefficient in Bohm diffusion is equal to Boltzmann's constant times temperature over 16 times charge times this. The Verdet constant relates this and the angle of rotation due to the Faraday effect. When a charged particle moves through one of these, the force can be given by the charge times the velocity crossed with this. In a solenoid, it is equal to current times turn density times the permeability constant. When using the right-hand-rule for a moving charge, the direction of this is represented by the middle finger, and inductors store their energy in these. Name this type of field measured in tesla, the lines of which one can see when spreading iron filings around a bar magnet.
