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.

Example Input: Harnik et al. argue against the anthropic principle by proposing a universe that lacks this. One instance of this interaction is modeled with a unitary matrix that includes three mixing angles and a complex phase that models CP violation. A vector minus axial Lagrangian for this force leads to maximal parity violation, making this force only affect left-handed particles. This force is responsible for quark flavor changing, was unified with electromagnetism by Glashow, Weinberg, and Salaam, and is transmitted by the massive W and Z bosons. For 10 points, name this fundamental force involved in radioactive decays.
Example Output: Science

Example Input: After allying with the khan of Chagatai and taking part in campaigns in Transoxania, this ruler would lose a "muddy battle" against Ilyas Khodja, despite fighting alongside brother-in-law Husayn of Balkh. Becoming the head of the Barlas upon the death of Tughluk, this man annihilated Tokhtamysh and the Golden Horde at the Battle of the Terek River before he overwhelmed Sultan Mehmud's forces in seizing the Delhi Sultanate. Prior to his death and ultimate succession by Shah Rukh while planning an invasion of China, he defeated the Turks at the Battle of Ankara and captured Bayezid I. FTP, name this Mongol military leader who ruled in Central Asia during the 14th century from his capital of Samarkand.
Example Output: History

Example Input: This man's namesake elasticity describes surface tension resistance when a surface is stretched, and can be applied to surface-tension-related mass transfer in an effect named for this man and Marangoni. For a mixture at constant temperature and pressure, the change in the chemical potential of the system can be obtained using an equation named for this man and Duhem. Another equation named for this man is used to calculate the degrees of freedom of a system depending in part on its number of components. For 10 points, name this man with a namesake phase rule and a thermodynamic quantity useful in predicting the spontaneity of a chemical reaction, his free energy.
