In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

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.
Fine Arts

The yield of these compounds can be increased through ball milling of some of their components, and one mode of operation of these compounds proceeds through a mechanism called enantiomorphic site control. A process for the operation of these compounds that proceeds through migratory insertions and obeys the "principle of least nuclear motions" was developed by Cossee and Arlman. Compounds such bis(cyclopentadienyl)titanium chloride and bis(indenyl)zirconium dichloride, known as metallocenes, have been developed as an alternative to the traditional compounds of this type. Those traditional initiators include vanadium trichloride and triethylaluminum, and the product of the application of these compounds to alkenes can result in syndiotactic, isotactic, or atactic products. For ten points, identify these stereoselective compounds used to initiate polymerization, named for a German and an Italian chemist.
Science

In one battle, this leader blew up all the bridges on the Neretva River to thwart forces under Alexander Lohr, and he was the target of Operation Knight's Leap. This leader signed the Treaty of Vis with Ivan Subasi. Fitzroy Maclean was this man's British liaison, and this ruler fought against the Ustasha and his nemesis Draza Mihailovi, leader of the Nazi-collaborationist Chetnik movement. This man put down the Croatian Spring, and his denial of the COMINFORM began the Informbiro period, part of his feud with Stalin. For 10 points, name this leader of the Non-Aligned Movement and dictator of Yugoslavia.
