Input: Consider Input: The elimination mechanism by which the dehydration of its major product occurs necessarily involves the abstraction of an acidic hydrogen and displacement of the leaving group. The catalyst in this reaction itself is regenerated from the deprotonation of water in its final step, which results in the conversion of its intermediate, an alkoxide. An aldehyde or ketone had originally undergone a nucleophilic-addition-type process to produce that alkoxide, which had converted it from a nucleophilic enolate using a hydroxide ion catalyst. Producing a final product known as a beta-hydroxyaldehyde, FTP, name this condensation reaction whose name combines that of its two final products.

Output: Science


Input: Consider Input: One of this composers title characters sings the aria Quand le destin au milieu to convince the Countess of Berkenfield not to force her to marry the Duke of Crackenthorp. In another of his operas, Dr. Malatesta sings Bella siccome un angelo when describing a fictional sister to the title bachelor, while the self-proclaimed genius Dr. Dulcamara sells the title object of another opera to Nemorino to allow him to woo Adina. Another of his operas contains the sextet Chi mi frena, after which Edgardo curses the entire Lammermoor family. For 10 points, name this Italian composer of Daughter of the Regiment, Don Pasquale, LElisir dAmore, and Lucia di Lammermoor.

Output: Fine Arts


Input: Consider Input: Interfacial tension is left unaccounted for by the phase separation model of these entitiesin the limit of low aggregation number, while the predictions of that model converge to the mass action model for higher aggregation number. Their degree of association counts the number of ions in their components, ignoring counterions, while their mass generally refers only to neutral ones and so includes counterions. They never form below the Kraft temperature, but above that temperature they form in a range called the critical concentration; that concentration is irrelevant to inverted ones, which form in nonpolar solvents and result in the hydrophilic heads of their monomers gathering together. Critical to the action of detergents, For 10 points, identify these spherical products of emulsification.
