TASK DEFINITION: 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.
PROBLEM: It begins in Scythia, in a locale characterized as "the world's limit an untrodden desolation. "  The title character doesn't speak until after Kratus and Bia, or Might and Violence, have left, soon after which he is visited by a Chorus of Ocean Nymphs, who like Hephaestus sympathize with the title character. It is to Oceanus that the title character recounts his tale, beginning with the war between the Gods and Titans. FTP, name this Aeschylus play about the tortured Titan whose foresight helped him give hope and fire to Man.

SOLUTION: Literature

PROBLEM: Instead of employing the Debye-Hull-Scherrer powder method, its namesakes relied on an array of atomic planes. Its namesakes built a vacuum apparatus and employed a hot filament, an accelerating electrode, and an arc-mounted Faraday box. A leak in the vacuum led its namesakes to heat the target, resulting in crystallized nickel, which gave startling results. A plot of collector current against beam energy was explained by constructive interference, and the results in general could be derived by combining Bragg's equation with the de Broglie wavelength for electrons. FTP name this experiment named for two physicists, which proved that electrons diffract.

SOLUTION: Science

PROBLEM: It was discovered in 1986 by Roger Davies, Alan Dressler and five other scientists collectively known as The Seven Samurai. Its discovery was made clear due to peculiarities in the Tully-Fischer relationship of up to 700 kilometers-per-second and is associated with a filament-like red-shift that is directed back at the observer; a pattern called the Fingers of God. Some astronomers believe that it is a supercluster with its center at Abell 3627, but since it lies within the Zone of Avoidance, studies made to research this object in the visible spectrum have been made difficult. This structure is located just in front of a 500 million light year long filament of both baryonic and dark matter called the Great Centaurus Wall. Recently estimated to be 250 million light years across, FTP, identify this gravitational anomaly that is named from its tendency to draw galaxies toward it.
