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:
To isolate volatile compounds from nonvolatile impurities, the steam form of this process is used when the compounds decompose at standard temperatures and pressures. Two miscible liquids are heated under a Liebig condenser to increase the concentration of the liquid with the lower boiling point in a common type of this process. FTP, name this separation method by boiling point, whose fractional variety yields cosmetics from petroleum and alcohol from a water mixture.

Ex Output:
Science


Ex Input:
Japan's Chikyu Hakken is trying to reach this region, and n-waves travel along its upper boundary. Post-perovskite forms in the bottommost part of this region, the D double prime layer. P-waves slow down and S-waves disappear past the bottom of this region, and its top features a P-wave velocity jump from approximately seven to approximately eight kilometers per second. The low velocity zone of the asthenosphere is found in the upper part of this region. It is sandwiched between the Gutenburg discontinuity and the Moho, and this layer's namesake plumes form hotspots. For 10 points, name this layer of the earth between the crust and the core.

Ex Output:
Science


Ex Input:
According to Fubini's theorem, the order in which this operation is performed does not matter. The surface variety forms the basis of the divergence theorem, while the line form of this operation can be calculated with Green's theorem. If one of their bounds is positive or negative infinity, they are known as improper. Depending on whether or not their endpoints are defined, they can be either definite or indefinite, and they can be approximated using Riemann's sum. For 10 points, name this operation in calculus which can be used to find the area under a curve.
