You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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. Another of his novels, The Road Back, is thought to be a sequel to his most famous book, in which the patriotic teacher Kantorek convinces Paul Bumer and his friends to join the Germany Army during World War I. For 10 points, name this German author who wrote All Quiet on the Western Front.
Solution: Literature
Why? The text is talking about an author and their works, so it belongs to theliterature category.

New input: Most proteins, such as Gelsolin, interact with this by binding in the hydrophobic cleft between its subdomains 1 and 3. That cleft can also bind subdomain 2 of a different molecule of this protein, a nucleation reaction mediated by the Arp 2/3 complex. Although it can be visualized with fluorescently tagged phalloidin, that treatment increases the amount of this protein at the cell membrane, where its normal functions include promoting cell adhesion by linking to cadherin via vinculin and catenins. Thymosin beta 4 maintains the cellular concentration of its free form, while profilin catalyzes its exchange of ADP for ATP and thus promotes its polymerization. Once polymerized, it can form dynamic structures such as lamellipodia and the contractile ring during cytokinesis. ATP hydrolysis causes globular monomers to be released from its filamentous form., and troponin regulates its binding of motor proteins in sarcomeres. For 10 points, name this cytoskeletal protein that forms microfilaments and is associated with myosin in muscle cells.
