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: In 1999, McIlroy created an adversary for this algorithm that guarantees that it will run in worst-case time. Its worst-case runtime can be avoided by switching to heapsort after a certain recursion depth, a construction known as introsort. Like mergesort, it is easily parallelizable, and its runtime can be decreased by first selecting the median of the unsorted input list. It was invented by C.A.R. Hoare, and its second phase is the partition function, which splits the original list into lists of elements that are greater or less than the chosen pivot value. For 10 points, identify this divide-and-conquer sorting algorithm which runs in big O of n log n time, named for its speed.
Example Output: Science

Example Input: This composer wrote "An du Natur" and 16 other songs for singer Therese Grob, whom he was too poor to marry. He also wrote many of his songs for Johann Michael Vogl, a baritone who greatly admired his work. His treatment of Goethe's Erlkoenig is particularly striking for its dramatic content, while one of his chamber pieces include a string quartet whose second movement is a set of variations on his song "Death and the Maiden. " For 10 points, name this composer of The Trout Quintet and The Unfinished Symphony.
