Question: This philosopher advocated the adoption of a federal system in Considerations on the Government of Poland. He contrasted the natural and physical types of the title concept in his Discourse on Inequality. He also wrote an epistolary novel subtitled The New Heloise, and a treatise dealing with the education of the titular boy, Emile. His most famous work discusses a society controlled by the general will of its people and asserts that man is born free, but is everywhere in chains. For 10 points, name this French philosopher who wrote The Social Contract.

Answer: Social Science


Question: Earthworms uniquely use the molecule lombricine to react with this molecule. This molecule activates P2X3 and P2X2/3, two receptors that control pain responses, and in conjunction with luciferin this molecule is responsible for the light of fireflies. In the muscular tissue of chordates, this compound donates a group to creatine. In proteins, this molecule, first synthesized by Alexander Todd, is almost always bound by a magnesium cofactor, and large quantities of this molecule are produced via oxidative phosphorylation in the electron transport chain. For 10 points, name this molecule discovered by Karl Lohmann,, the energy currency of the cell.

Answer: Science


Question: One reaction of this type reacts alpha, beta-unsaturated carbonyls with Hantzsch esters under amine catalysis. Discoverers of an asymmetric version of this reaction used in the industrial synthesis of L-DOPA from an achiral arene won part of the 2001 Nobel Prize in Chemistry. That asymmetric form of this reaction can be catalyzed by ruthenium-BINAP complexes developed by Noyori. A square-planar tris(triphenylphosphine) rhodium(I) complex was developed in 1966 to homogeneously catalyze this reaction; that is Wilkinson's catalyst. When this reaction is incomplete, it can result in cis-trans isomerization, and thus its "partial" form is responsible for the production of trans fats. For 10 points, name this reduction that involves reacting a substrate with the namesake light gas.
