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.

Ex Input:
First proposed by Lewis, it is related logarithmically to a gas's standard Gibbs free energy divided by the temperature and gas constant. At equilibrium, this quantity must be equal in both gas and liquid phases. Taking the derivative of the natural log of this function is equates it to the derivative of a reaction's chemical potential. Equal to the gas' pressure when the gas is ideal, FTP, identify this thermodynamic quantity which replaces partial pressure when working with real gases and describes the tendency of a substance to escape from its current phase, symbolized by f.

Ex Output:
Science


Ex 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.

Ex Input:
The creation of these cells is aided by the phosphorylation of LAT by ZAP-70, which is recruited by Lck. The TSLP protein assists in the creation of these cells. These cells express ICOS, but not its ligand. Secretory vesicles in these cells can contain the protein perforin, and they can also express the Fas ligand. Unlike some similar cells, these cells do not undergo somatic hypermutation, but they do undergo V(D)J recombination. MHC proteins present foreign peptides to these cells, which can contain the coreceptors CD4 and CD8. These cells are part of the cell-mediated immune response, distinguishing them from the antibody response. The two main classes of this cell are cytotoxic and helper. For 10 points, identify these lymphocytes that that mature in the thymus, unlike B cells.
