[Q]: In the form of Nicippe, the priestess of a grove at Dotium, this figure threw the curse of perpetual hunger upon the man who tried to chop down her grove, Erysichthon. With the titan Iasius she produced the children Philomelus and Ploutus. In another story, she assumes the form of the old woman Doso and her (*) sadness is alleviated somewhat by the jokes of Iambe, after which she bathes a baby boy in fire every night in order to burn away his mortality. This stay in the house of Demophoon' parents is described in the Homeric hymn to this figure which describes the foundation of the Eleusinian mysteries. For 10 points, name this Greek goddess who gave Triptolemus a plow and some other agricultural tools, and who was the mother of Persephone.
[A]: Social Science

[Q]: A maximum independent set for this data structure can be found in linear time by adding alternating levels. In this structure, any two vertices or nodes must be connected by a single simple path, and thus it is connected and acyclic. By using (*) union-find with disjoint sets, one type of this structure containing all the vertices of a connected graph can be constructed. One variety of this data structure can be used to easily implement a binary search. This structure also comes in red-black and self-balancing-binary varieties. For 10 points, identify this data structure from computer science, a hierarchical graph in which "leaf" nodes ultimately flow from a "root" node.
[A]: Science

[Q]: A persistent rumor contemporary with this paintings first exhibition in 1782 had it that the artist ate raw pork for inspiration. On the stand at the lower left are glass and clay jars which some critics suggest could contain laudanum, while the central figures are framed by a burgundy drape in the background which matches the sheet on which the prone female lies. The animal in the upper left has pale eyes with no iris or pupils visible, while the figure atop the woman looks at the viewer pensively with his left hand cradling his chin. Loaded with sexual overtones and featuring a horse looking on while an incubus sits on a sleeping womans chest, for 10 points, name this work by Henry Fuseli depicting a bad dream.
