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]: The reciprocal relationship between the eigenvalues of the mass matrix of these particles is called the "seesaw mechanism"; the larger eigenvalue may be the mass of their "sterile" variety. One phenomenon predicted by Pontecorvo involving these entities was searched for by (*) MINOS. Reines and Cowan used an aqueous cadmium chloride solution to detect them, and other detectors tend to include large volumes of material, such as Super Kamiokande. For 10 points, name these leptons, the nearly massless products of radioactive decay whose varieties include the muon and tau and which are represented by the letter nu.
[A]: Science


[Q]: This work cites Proudhon's Philosophy of Poverty as an example of a form of a philosophy to which it claims economists, philanthropists, and humanitarians belong. Its second section advocates a ten-point program which calls for the establishment of industrial armies as well as free education for all children in public schools. That section follows one which examines the history of the (*) bourgeoisie and the proletarians and claims that the history of society is a history of class warfare. For ten points, name this work authored by Friedrich Engels and Karl Marx, which discusses how the problems of capitalism would be solved by adopting socialism and eventually the title ideology.
[A]: Social Science


[Q]: In a modified form of this reaction, diethyl ether is used in the synthesis of cholestane. Other more notable modifications of this reaction include one that uses formic acid and ethanol to produce aryl alkenes and one that uses toluene in the Martin modification. One proposed mechanism uses a carbenoid intermediate, although it is agreed this reaction uses electrons supplied by the oxidation of a metal. It is analogous to another reaction run under basic conditions which can modified in a one pot process named after Huang and Minlon. For 10 points, identify this chemical reaction which uses zinc amalgam and hydrochloric acid and, like the Wolff-Kishner reduction, reduces aldehydes or ketones to alkanes.
