TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: Science

PROBLEM: The artists friend Meyer de Haan appears with two semi-nude women surrounded by flowers in his Barbarian Tales. A naked black woman lies on her stomach on a green bed in one painting by this painter. He drew a tree branch to set off the main action taking place on a vermillion background in another work. This painter of Spirits of the Dead Keep Watch and Jacob Wrestling with the Angel also painted a religious figure surrounded by Breton women. He depicted an old woman with a white bird at her feet representing the final stage of life in another painting. For 10 points, name this French painter who painted The Yellow Christ and Where Do We Come From What Are We Where Are We Going while living out his life on Tahiti.

SOLUTION: Fine Arts

PROBLEM: Its formulator extended it by citing work that he had performed under Kolbe, while Henrys independent discovery of this statement led to another generalization by its formulator. Hornback explained it in terms of positively-charged intermediates, and this statement is notably abrogated in a procedure sometimes named for Herbert Brown. Often paired with a similar rule that governs eliminations, Zaitsevs rule, this rule is violated in reactions using peroxides and in hydroboration reactions due to steric hindrance. FTP, name this rule from organic chemistry that states that when a halide adds to an alkene, the more substituted carbon attaches the halide, named for a Russian chemist.
