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.

Input: Consider Input: Ninhydrin forms a Schiff base with this chemical, resulting in a hue known as Ruhemanns purple. The Birch reduction takes place in a liquid substrate of it, the reason it is common in methamphetamine labs. The Kjeldahl method uses this molecule as an end-product to measure the amount of nitrogen in a sample, and it is oxidized in the first step of a nitric acid forming procedure, the Ostwald process. For 10 points, name this weak base found in fertilizers, formed by combining hydrogen and nitrogen in a three-to-one ratio in the Haber process.

Output: Science


Input: Consider Input: This work contains the lines, "The swallow tittering from the straw-built bed, the cock's shrill clarion, or the echoing horn, no more shall rouse them from their lowly bed" before claiming that "Full many a gem of purest ray serene the dark unfathom'd caves of ocean bear". Another section of this work discusses how "Knowledge to their eyes her ample page, rich with the spoils of time, did ne'er unroll" and "beneath those rugged elms, that yew tree's shade, where heaves the turf in many a mouldering heap, each in his narrow cell for ever laid". This work begins with the lines, "The curfew tolls the knell of parting day, the lowing herd winds slowly o'er the lea". For 10 pointsname this poem by Thomas Gray.

Output: Fine Arts


Input: Consider Input: This celestial object is the largest in a namesake class of bodies that have 2:3 mean motion resonance with a certain larger body. Nix and Hydra are two satellites of this body, the presence of which was originally predicted by Perceval Lowell. The New Horizons probe is en route to this celestial object. The discovery of Eris raised controversy regarding this object, which was discovered by Clyde (*) Tombaugh. It and its largest satellite are sometimes referred to as a binary planet system, although Charon is still officially classified as a moon of this body. This body's highly eccentric orbit occasionally brings it closer to the Sun than Neptune. For ten points, identify this celestial object that was stripped of its "planet" status in 2006.
