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.

[Q]: This molecule facilitates the Griesbaum reaction and cleaves an alkene to forms an aldehyde or a ketone in a 1,3 dipolar cycloaddition, the Criegee mechanism. In the Chapman Cycle, this diamagnetic compound with a bent geometry is replenished by a paramagnetic, diatomic molecule. In that reaction, this molecule is formed by the absorption of a photon with a wavelength of less than 280 nanometers. It can be depleted by chlorofluorocarbons, making the Earth more susceptible to ultraviolet radiation. For 10 points, name this molecule found in a namesake atmospheric "layer", a triatomic allotrope of oxygen.
[A]: Science


[Q]: In this work, a definition of justice as "what is good for the stronger" is given by Thrasymachus. In this work, a story about the killer of King Candaules of Lydia is used to describe how people are just out of necessity. That story in this work tells of the [*] "Ring of Gyges." This work describes chained prisoners who watch shadows pass before them. This work combines ideas about the "divided line" and the sun into its "Allegory of the Cave." For 10 points, name this work that proposes a government ruled by philosopher kings, a dialogue on government by Plato.
[A]: Literature


[Q]: This molecule's namesake "synthase" consists of an --- complex whose active sites are joined by a solvent-filled tunnel, according to the structure determined by Hyde, Miles, and Davies. Unlike two similar molecules whose hydroxylations also exhibit the NIH shift, this molecule's biosynthetic pathway includes anthranilate. One intermediate in its degradation pathway spontaneously forms (*) quinolate, and that pathway's last seven steps are identical to that of lysine. The aroH operon shares a repressor with two E. coli operons named after this amino acid, and a decarboxylase converts its 5-hydroxy form to serotonin. For 10 points name this essential amino acid that contains an indole group, is symbolized W, and is responsible for feelings of sleepiness after eating too much turkey.
