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.

Input: Consider Input: One of this author's works argues that "political emancipation" is compatible with religion, but blocks
the fulfillment of "human emancipation." In another of his works, he developed his theory of "base and
superstructure." This opponent of Bruno Bauer wrote that "Philosophers have only interpreted the world;
the point is to change it" in his Theses on Feuerbach, as well as writing On the Jewish Question. Another
of his works argues that a commodity attains value through the amount of labour put into it. For 10 points,
name this German philosopher who, along with Engels, wrote Das Kapital.

Output: Social Science

Input: Consider Input: In studying this structure, Elizabeth Gould showed that dendrite spine density and estradiol levels peaked together. A circuit of structures interconnecting this structure and the cortex was proposed by James Papez, and axon collaterals named for Schaffer innervates neurons in the CA1 portion of this structure. Neurons that respond only when an animal is in a certain region of space, known as place cells, are located in this structure. It consists of two sheets of neurons called Ammon's horn and the dentate gyrus, the first of which sends axons into the fornix. Connected ventrally and laterally to the olfactory cortex, this structure inhibits CRH release. For 10 points, name folded structure of the limbic system that plays a major role in learning and memory.

Output: Science

Input: Consider Input: Particle detectors that utilize this effect can emit pulses with widths as low as 10-10 (read: 10 to the minus 10) seconds and can be used in time-of-flight measurements. The angle of emission is related to the speed of light and the index of refraction of the medium, and measuring the angle can determine the particle's speed. Discovered by Frank and Tamm and predicted by its namesake, FTP, identify this effect where a blue light is emitted from a particle when it passes into a medium at a speed greater than the speed of light in that medium.
