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: This organ produces a tetrapeptide, which bonds to macrophage receptors, and is known as tuftsin. The sinusoids of one portion of this organ contain blood and a reserve of monocytes which can be utilized in the case of hemorrhagic shock. The other major portion of this organ contains Malphigian corpsules and synthesizes antibodies. Located in the abdominal region and consisting of red and white pulp, for 10 points, name this organ part of the lymphatic system that helps to filter and clean the blood.
Example Output: Social Science

Example Input: It is equal to the enthalpy change minus the temperature times the entropy change. Under standard conditions, it is also equal to negative R T times the natural log of K, where R is the gas law constant, T is the absolute temperature, and K is the equilibrium constant for the reaction; thus a high negative value indicates a forward-going reaction. FTP, identify this quantity, named for a Yale chemist, which is a measure of the spontaneity of a reaction.
Example Output: Science

Example Input: Bounds for the largest coclique of an undirected, simple, loopless graph on n vertices can be found due to the interlacing of these quantities. These quantities are lowest when the Rayleigh quotient is minimized. Bounds on these quantities can be obtained using the minimax theorem of Courant and Fisher. These quantities lie in the union of closed discs in the complex plane according to a theorem of Gersgorin. Schur showed that they majorize the diagonal elements of a Hermitian matrix. If A and B are m by n and n by m complex matrices, then AB and BA have the same nonzero value for this quantity, counting multiplicity, and, as a consequence, their traces are equal. These quantities are the zeros of the characteristic polynomial. For 10 points, identify these quantities that scale an eigenvector.
