Q: Cities on its shores include Kibwesa, Wapembe, and Mpala, and the Mushara, Murembwe and Dama end in it. A source of great biodiversity, its namesake sardine is an important food source for locals. Despite its depth, the lower regions are mysteriously only a few degrees colder than the surface. In rainy years water from it flows into the Lukuga River and then into the Lualaba. John Speke and Richard Burton were the first two westerners to find it, and Henry Stanley found David Livingstone at Ujiji on its shores. It felt a 6.5 magnitude earthquake in 2005 due to a shift in the fault that is responsible for the Great Rift Valley, and it borders four countries including Burundi and Tanzania.

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: This writer borrowed Emile Benveniste's divide between the system of history represented by the aorist tense and the system of discourse in an essay that outlines the rise of the middle voice and questions the transitivity of a certain verb. Another of his works lays out a topos formed by the referential, symbolic, semic, proairetic, and hermeneutic codes. He may be best-known for an essay that claims that language "knows a subject, not a person" and advocates the advent of the "scriptor". For 10 points, name this structuralist who analyzed Balzac's "Sarrasine" in his S/Z and who claimed that "the birth of the reader must be at the cost of the death of the Author".
