PROBLEM: This molecule facilitates the Griesbaum reaction and cleaves an alkene to forms an aldehyde or a ketone in a 1,3 dipolar cycloaddition, the Criegee mechanism. In the Chapman Cycle, this diamagnetic compound with a bent geometry is replenished by a paramagnetic, diatomic molecule. In that reaction, this molecule is formed by the absorption of a photon with a wavelength of less than 280 nanometers. It can be depleted by chlorofluorocarbons, making the Earth more susceptible to ultraviolet radiation. For 10 points, name this molecule found in a namesake atmospheric "layer", a triatomic allotrope of oxygen.

SOLUTION: Science

PROBLEM: During his lame-duck period, he appointed Nathan Goff, Jr., as Secretary of the Navy to replace Richard Wigginton Thompson, and other members of his cabinet included Secretary of the Interior Carl Schurz and Attorney General Carl Devens. Pozo Colorado is the capital of a department named after him in Paraguay, where he is a national hero, having arbitrated in their favor while president after the War of the Triple Alliance. Congress overrode his veto of the (*) Bland-Allison Act, and he promised not to run for a second term after a supposed bipartisan committee rewarded him 20 disputed electoral votes. FTP, name this 19th president who won a controversial election in 1876 against Democrat Samuel Tilden.

SOLUTION: History

PROBLEM: Vincenzo Scamozzi completed a work of this man found across from St. Mark's. The Foscari, Sarego, and Godi are some of the examples of his most characteristic genre, but perhaps his most famous (*) design was for Giulio Capra at Vicenza. This creator of San Giorgio Maggiore and author of The Four Books of Architecture inspired the shape of Monticello. For 10 points name this designer of the Villa Rotonda.
