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.

Martin and Primavesi recently discovered a fragment of this thinkers treatise On Nature. This man wrote the poem Katharmoi, but Aristotle excluded this mans works from the Poetics because while it was written in hexameter, it does not characterize its subject matter as a representation of life. OBrien, Wright, and Aristotle all claimed that this man adhered to a cyclical view of the universe, and this thinker also argued that human limbs once lived on their own. He wrote an autobiography known as the Purifications, in which he said that he was a vegetarian because animals contain transmigrated human souls. This man believed that all matter was once a sphere, which dissolved into the present world. He argued that neikos and philia drove the world, with strife separating substances and love bringing them together. This Sicilian is said to have died by throwing himself into Mt. Etna. For ten points, name this pre-Socratic philosopher who argued that the world was divided into four elements: water, earth, wind, and fire.
Social Science

This ruler faced a scandal when Amy Robsart, the wife of Robert Dudley, died by falling down some stairs. This ruler was dubbed a "servant of crime" and excommunicated in the papal bull Regnans in Excelsis, a response to the passage of the Second Act of Supremacy. Anthony Babington's plan to assassinate this ruler was uncovered by spymaster Francis Walsingham. This ruler ordered the execution of Mary, Queen of Scots and sent Francis Drake to defeat the Spanish Armada. For 10 points, name this Tudor monarch, the "Virgin Queen" of England.
History

When the Butler-Volmer equation is used to describe the charge transfer reaction rate, this equation is used to describe the open circuit potential, except in the case of intercalation electrodes, for which it does not hold. One variant of this equation calculates membrane potential provided membrane permeability and ion concentration, the Goldman-Hodgkin-Katz equation. The change in Gibbs free energy is directly proportional to this equation, which is used to find a cells electric potential. For 10 points, identify this equation, named for a German chemist, which allows one to find either the electromotive force or standard electrode potential, provided the reaction quotient is known.
