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 Q]: This region experiences a type of fog that is known as camanchaca. The main river that passes through this area is the Loa River. This region is bound on the west by the Cordillera de la (*) Costa and on the east by the Cordillera Domeyko. For 10 points, name this location often considered to be the driest on the Earth, which runs alongside the Andes Mountains and is a desert located in northern Chile.
[EX A]: Social Science

[EX Q]: 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 A]: Science

[EX Q]: One coupling reaction links an aryl halide with an acetylide of this metal, while in another reaction it is used as a catalyst to link an alkyne and a bromoalkyne. In addition to the Castro-Stephens and the Cadiot-Chodkiewicz coupling, alkenyl compounds of this element can be created via the Normant reaction. The iodide of this element is a catalyst in the (*) Gatterman-Koch reaction, and this element is present in the A solution of the Fehling test. Gilman reagents contain lithium and this other metal, while the 2+ ion of this element forms a bright blue solution. For 10 points, name this element, a metal used in electroplating and plumbing, with atomic number 29 and symbol Cu.
