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.

Ex Input:
The attenuated total reflection type of this can be used on compounds with a low surface area, while the diffuse reflectance type can be used to study samples that are not sufficiently transparent. The multiplex advantage explains the use of the Fourier Transform type of this. Diatomic bonds are generally not found in the fingerprint region, and the stretching seen using this technique generally occurs at higher frequencies than the bending. Most types of this use some sort of absorption, because each bond in the molecule will absorb only its characteristic frequency. For 10 points, name this type of analytical technique, which categorizes compounds based on the frequency of the vibration of its bonds when exposed to radiation of waves longer than those of visible light.

Ex Output:
Science


Ex 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.

Ex Output:
Science


Ex Input:
accelerates the isomerization of one type of these compounds in a zipper-like fashion. The Glaser Coupling results in the joining of two of these compounds, and they can be synthesized through the Corey-Fuchs reaction. Potassium permanganate oxides these compounds to two carboxylic acids, and they can be selectively reduced to a similar functional group in the presence of a palladium catalyst named for Lindlar. The central carbon atoms in these groups have sp hybridization, and the two unhybridized p orbitals form the two pi bonds in these groups. For 10 points, name these compounds containing a carbon-carbon triple bond.
