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: One reaction to prepare these compounds adds diazomethylphosphonate esters to aldehydes under basic catalysis and generates vinyl-diazo intermediates. Along with aldehydes, these compounds are the degradation products of alpha, beta-epoxy tosylhydrazones in the Eschenmoser fragmentation. A coupling involving both palladium and copper catalysis, in which these compounds react with aryl halides, is the Sonogashira reaction. These compounds react with azides to form triazole rings in a well-known click-chemistry reaction, and terminal ones can be deprotonated by sodium amide. They are reduced to cis-alkenes by the poisoned Lindlar catalyst. This functional group is composed of two sp-hybridized carbons. For 10 points, name this functional group consisting of a carbon-carbon triple bond.

Output: Science


Input: Consider Input: Iannis Xenakis used eight so-called "sound complexes" in a solo work for this instrument called Nomos Alpha. Six beats on the body of these instruments begin the main theme in Arvo Part's orchestration of Fratres for twelve of them. An ensemble consisting entirely of these instruments was founded in the 1970s by twelve members of the Berlin Philharmonic. The first of Villa-Lobos's Bachianas Brasileiras was composed for (*) eight of these instruments, while Jacqueline du Pre popularized Edward Elgar's concerto for it. J.S. Bach's six unaccompanied suites for this instrument were famously recorded by both Mstislav Rostropovich and Pablo Casals. For 10 points, name this instrument played by Yo-Yo Ma which joins two violins and a viola in a string quartet.

Output: Fine Arts


Input: Consider Input: One president at the time of this war defended his country's involvement by promising ""peace without conquest. "" The commanders of U.S. operations in this war were William Westmoreland and Creighton Abrams. This war began with an air offensive called Operation Rolling Thunder. During this war, the United States was dealt a psychological blow by the Tet Offensive. This war was sparked after the USS Maddox was attacked, leading to the Gulf of Tonkin Resolution. For 10 points, name this war in Southeast Asia that lasted from 1965 to 1975.


Output: History
