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: 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: This philosopher advocated the adoption of a federal system in Considerations on the Government of Poland. He contrasted the natural and physical types of the title concept in his Discourse on Inequality. He also wrote an epistolary novel subtitled The New Heloise, and a treatise dealing with the education of the titular boy, Emile. His most famous work discusses a society controlled by the general will of its people and asserts that man is born free, but is everywhere in chains. For 10 points, name this French philosopher who wrote The Social Contract.
Example Output: Social Science

Example Input: In a material with this property, the remanence refers to its magnitude in the absence of a driving force, while coercivity measures how strong a field is needed to remove this property. Its lack of retraceability is noted by a hysteresis loop, and this phenomenon can be attributed to the unfilled energy levels in the 3d level of certain elements. The susceptibility of materials possessing this property can be determined by the Curie-Weiss law beyond a specific point. It is a result of permanent unpaired dipoles within domains that line up with an imposed magnetic field due to long range ordering. Once materials exhibiting this property surpass the Curie temperature, they tend to behave as paramagnets. FTP, name this form of magnetism common to particular metals, most notably observed in nickel, cobalt, and iron.
