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: One of these organic compounds is converted to an alkene by a diorganochromium compound in the Takai olefination. Compounds may be reduced to this functionality via the use of DIBAL-H (die-bahl aitch), and alkynes are formed by a reaction of these compounds with tetrabromomethane and triphenylphosphine named for Corey and Fuchs. When these organic compounds lack a hydrogen atom in the alpha position, their disproportionation can be induced by a base in the Cannizzaro reaction. These organic compounds are oxidized to carboxylic acids by a diamminesilver (I) complex, leading to the precipitation of metal onto the inside of the vessel, giving the positive "silver mirror" result of the Tollens test. For 10 points, name this special class of ketones with one R group being just hydrogen.

Q: After watching a boxing match between two angry dwarves, Dan Moore yells Jesus was once a leper! in one story in this collection. In addition to Box Seat, it includes stories about Esther, who loves the mystic King Barlo, and Becky, who is shunned for bearing mulatto sons. Another story in it describes Seventh Street, which infuses black reddish blood into the white and whitewashed wood of Washington, and a white mob burns Tom Burwell alive for killing Bob Stone in its story Blood-Burning Moon. Its authors time in rural Georgia inspired its final section, Kabnis. Beginning with a story describing the beauty of Karintha and a poem about the Black Reapers of the title plant, FTP, name this modernist collection of short stories and poems by Jean Toomer.

Q: One perturbative solution to this kind of problem takes the form of an infinite series of Feynman  diagrams that diverges. When finding an approximation for this kind of problem in the case of long  wavelengths, the exponential term simply vanishes and all that must be integrated is the interaction  potential; that is a special case of the Born Approximation. In quantum mechanics, this kind of  problem usually is solved by finding the associated (*) amplitude of a wave, given that a plane wave encounters a potential and is transformed into a spherical wave. Classically, this type of problem is  typically solved by finding the namesake angle given the impact parameter. For 10 points, name this  kind of process in which a particle changes direction after a collision.
