PROBLEM: Occlusion by this astronomical body of Saggitarius Tr-180 suggests that the rate of sublimation from its surface has doubled. That sublimation may have helped to create evaporite deposits such as the Akupara and Rem maculae, which cover a surface of beta-hexagonal ice surrounding the Plain of Abatus. Its changing albedo is believed to couple with gravitational diapirism to produce the cavi of its unique terrane of Bubeme. Perhaps the most interesting surface features occur in its equatorial region, which contains fault-block mountain ranges bounded by the Ho and Lo sulci, indicating a tectonic past, and the geyser plumes Hili and Mahilani, which contribute to its thin atmosphere. FTP, name this moon of Neptune best known for its cryovolcanic eruptions and its retrograde orbit.

SOLUTION: Science

PROBLEM: One opera by this composer ends with Death departing and Satyavan coming back to life. In addition to Savitri, he composed the opera At the Boar's Head. Orchestral works by this composer include the Thomas Hardy inspired tone poem Egdon Heath, and a work named for the school where he taught, St. Paul's Suite. The movements "Song of the Blacksmith" and "Fantasia on the Dargason" conclude his Second Suite in F for Military Band. His best-known work was inspired by astrology and contains seven movements, the first of which features an ostinato rhythm in 5/4, and is entitled "Mars, the Bringer of War. " For 10 points, name this English composer of The Planets.

SOLUTION: Fine Arts

PROBLEM: A recent article by Manning, Levine, and Collins questions the assumptions behind the study that first showed this effect. Among the props used in that study was a case of beer; another experiment in that study used a male pre-med student as a confederate. Among the findings of that Latane and Darley study were that 90% of subjects refused to exit a smoky room when two confederates ignored the smoke; 31% of subjects reported a seizure when they thought there were four other people around to do it; and nobody reported a lady falling and moaning about a hurt leg. First inspired by the murder of Kitty Genovese in the presence of apparently 38 possible witnesses, for ten points, identify this effect in which people stand around and assume someone else is going to do something about an emergency.
