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: When reacted with a nitrile, they produce an imine anion that can be hydrolyzed into a ketone, and they can cause nucleophilic ring opening of epoxides. Pouring a solution of them over dry ice followed by protonation results in carboxylic acids, which will not form addition products with these. One of their most common uses is reacting with aldehydes and ketones to form secondary and tertiary alcohols, respectively. Because they essentially act as carbanions, they can be protonated by weak acids to yield alkanes. FTP name these organometallic reagents that are formed by reacting an alkyl halide with magnesium, named for their French discoverer.

Output: Science


Input: Consider Input: The Soave equation adds an acentric factor to this statement, and the virial equation measures deviations from this law using a compressibility factor. This law derived by Benoit Clapeyron can account for density in its "dirty mop" form, and when A and B terms are added to account for the volume and interactions between particles, it is called van der Waals equation. Containing a namesake constant that is Boltzmann's constant times Avogadro's number is, for 10 points, what law usually stated as PV equals nRT

Input: Consider Input: A slightly cut edition of the second of these compositions was prepared by Alexander Siloti, and the first of these contains one movement based on the cabaret song "Il faut s'amuser, danser et rire," while another movement contains an allegro section inspired by a blind beggars' song. The third and last of these was constructed of unused material from the composer's unfinished "Symphony in E-Flat. " The composer received a bitter lashing from Anton Rubenstein after playing him the first of these works, which was premiered in Boston under B. J. Lang with Hans von Bulow as the soloist. That work opens with a four-note motif sounded by all four horns punctuated by orchestral chords, which starts in the home key of B-flat minor but quickly modulates to D-flat major. For 10 points, identify these works for a keyboard instrument and orchestra by the composer of the Pathetique Symphony.
