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: In one work this author details the life of a tomb-maker who makes extra money by playing the organ at an insane asylum, while another of his novels sees Swartz give a refugee proper documentation only after he tells him his life story in the title Portuguese city. In addition to The Black Obelisk and The Night in Lisbon, he also wrote about Robert and Otto selling their auto workshop and visiting Patrice in a Swiss tuberculosis sanatorium in his novel The Three Comrades, while the turbulent life of the German surgeon Ravic is told in The Arch of Triumph.

For 10 points, name this German author who wrote All Quiet on the Western Front.
Example output: Literature
Example explanation: The text is talking about an author and their works, so it belongs to theliterature category.
Q: quantum version of this quantity is equal to electron charge squared times the density of states at the Fermi energy and is used to describe two dimensional electron gases. For a concentric sphere with opposing charges on the spheres, this quantity is derived by first using Gauss's law to find the Electric Field between the spheres. Eventually, that method gives a value of 4 pi times the product of the two radii divided by the difference of those two radii for the concentric sphere. In (*) series, it is calculated as the harmonic sum of the individual values of this quantity, while in parallel, this quantity is additive. It is often calculated by dividing charge by voltage. For 10 points, name this quantity measured in farads, defined as the ability to store electrical charge.
