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.

Example 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.
Example Output: Science

Example Input: In contrast to the internal, or L1 type, the L2 type sits between the CPU and DRAM, but both L1 and L2 are made of high-speed SRAM for the memory type. This disk type actually uses main memory, but stores information in a memory buffer. The original Pentium processor had a 16 kilobyte one of these built into it. FTP, name this high-speed storage mechanism that keeps frequently accessed data in a location separate from the main memory for rapid recall.
Example Output: Science

Example Input: An airport in this city that was decommissioned in 2008 and notable for being built from limestone will now be the home of the Bread and Butter fashion show for the next decade. One of its main public areas is named for a Russian Tsar who visited in 1805 and is the home to a massive TV tower that is the largest freestanding structure in western Europe. Other major public places include Gendarmenmarkt, home of the concert hall and the so called "French" and "German" cathedrals, and Postdamer Platz, which lies just south of Unter den Linden, the Brandenburg Gate, and the Reichstag. For 10 points, name this capital of Germany.
