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 major pathway involving this compound is the tuberoinfundibular one that transfers it from the hypothalamus to the pituitary gland. This compound is involved in voluntary motor control via its nigriostriatal pathway, and it binds with lactotrophs in order to inhibit the secretion of prolactin, which is a major antagonist of it. It is the immediate precursor of norepinephrine in the epinephrine synthesis pathway. Antagonists of this neurotransmitter are used to treat schizophrenia, and deficiency of this neurotransmitter can lead to Parkinsons disease. For 10 points, name this neurotransmitter associated with the brain's pleasure center whose precursor is L-dopa.

Output: Science


Input: Consider Input: Loewner's inequality relates the area and systole of Riemannian metrics on one of these spaces. Arnold's cat map is a chaotic mapping from one of these spaces to itself. This name is given to connected, compact, abelian Lie subgroups, and any compact Lie group has a maximal one. Dupin cyclides are geometric inversions of these objects, and two Villarceau circles can be created by cutting one of these objects diagonally. N-dimensional versions of these objects, which have genus one, are homeomorphic to the Cartesian product of N circles. Other than the Klein bottle, these are the only closed, compact surfaces with an Euler characteristic of zero. They can be created by revolving a circle around an axis coplanar to the circle's diameter. For 10 points, name these mathematical objects that often look like doughnuts.

Output: Science


Input: Consider Input: For an RLC circuit, the frequency associated with this effect is where impedance is at a minimum. Substances can be analyzed through a technique that uses the nuclear magnetic form of this effect. That technique's commonly used medical variant is called MRI. This effect causes the amplitude of a system to hit a maximum. For a vibrating string, the frequencies of this are multiples of the fundamental. For 10 points, name this effect where the frequency of the input force equals the natural frequency of the system.
