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.

Example Input: In political thought, this man contributed a comparison of socialism, anarchism, and syndicalism, three of the titular Roads to Freedom. In another work sometimes viewed as a sequel to his What I Believe, he critiqued organized religion and as a whole, writing that "No one can sit at the bedside of a dying child and claim to believe in God" in an attempt to explain Why I Am Not a (*) Christian. Other works by this man include one written with Alfred North Whitehead, in which he explained the whole of mathematics in terms of logical expressions. For 10 points, name this modern British philosopher who wrote Principia Mathematica.
Example Output: Social Science

Example Input: One reactant for this reaction is best prepared by an S N 2 nucleophilic addition of a triphenyl compound, followed by elimination of the hydrogen halide by an organolithium reagent. This reaction itself proceeds through a rather unique intermediate formed when the pi electron from the reagents carbon-oxygen double bond migrates to the positively charged pole of one reactant; this intermediate is called a an oxaphosphetane, from which a triphenyl oxide is eliminated to complete the reaction. The aforementioned positively charged pole is on phosphorous because the aforementioned prepared reactant is a phosphorous ylide. For ten points, name this reaction that produces selectively double-bonded alkenes from aldehydes and phosphorous ylides and that is named for the German 1979 Chemistry Nobel winner.
Example Output: Science

Example Input: One possible cooperative example of this effect is the vibronic theory of ferroelectricity, an idea that was first suggested by Bersuker. Longuet-Higgins was responsible for the first demonstration of this effect in optic spectroscopy by calculating energy levels of a system with the E-e problem. This effect is similar to the RTE, and the pseudo type of this is demonstrated in the stereochemical non-rigidity of molecules and ions as well as in fluxional behavior. This is most often encountered in octahedral complexes of the transition metals as well as six-coordinate copper II complexes. For ten points, name this doubly-eponymous effect where non-linear molecules experience a geometrical distortion under certain conditions.
