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:
This quantity can be defined as minus the temperature times the derivative of entropy with respect to particle number. The Gibbs factor is a generalization of the Boltzmann factor that takes this quantity into account. Usually defined as the derivative of the Helmholtz free energy with respect to particle number, FTP name this quantity which governs particle flow, as particles flow from systems with higher values to systems with lower values.

Ex Output:
Science


Ex Input:
Mobility is related to the zeta potential, dielectric constant, and this quantity in the Smoluchowski equation. For gases, the variation of this quantity with temperature is given by Sutherland's formula. Measured with a Zahn cup, this quantity is squared in the Grashof number, and the ratio of this quantity to thermal diffusivity is the Prandtl number. When this quantity is zero, the Euler equations correspond to the NavierStokes equations. Reynolds number is the ratio of inertial forces to this quantity, which is constant for Newtonian fluids. Measured in poise [PWAHZ], this quantity is zero for superfluids. For 10 points, name this internal friction of a fluid that tends to resist its flow.

Ex Output:
Science


Ex Input:
This subject of the Herman Melville poem ""The Portent"" was the subject of a propagandist ""authorized"" biography by James Redpath. The magazine of the Weather Underground was named after the site of one of this man's deeds. Robert Penn Warren's first published book attempted to debunk myths about this man and was a biography subtitled The Making of a Martyr. A poem by John Greenleaf Whittier repeated the legend that this man kissed a (*) slave baby as he was led to the gallows. For 10 points, name this anti-slavery radical whose ""Body"" provides the title of a Stephen Vincent Benet poem about this man's raid on Harper's Ferry.
