Question: One member of this phylum, Strongylocentrotus purpuratus, is often used to study developmental processes, and another, Pisaster ochraceus, is an example of a keystone species. Most members of this phylum have pedicellariae that possess three jaws, and some have a chewing apparatus known as Aristotle's lantern. Members of class Asteroidea of this phylum have an ambulacral groove, and the madreporite is the entrance to their water vascular system that includes tube feet. FTP name this phylum whose "spiny skinned" members have radial symmetry and include sand dollars, sea urchins, and sea stars.

Answer: Social Science

Question: 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.

Answer: Science

Question: In one work by this composer, the "Mystic Circles" movement's melody calls back to the previous movement. An opera by this composer tells the story of Anne Truelove and Tom and is based on a William Hogarth painting series. This composer of The Rake's Progress created a ballet with a "Berceuse" before its finale. In that work, an "Infernal Dance" is performed by Kashchei. One of this man's ballets opens with a high register bassoon solo, and nearly caused a riot at its premiere because of provocative choreography by Vaslav Nijinsky and the near-atonal music. For 10 points, name this composer of The Firebird and The Rite of Spring.
