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: A character created by this author socializes with Billy through sex with Billy's sister Trudy. In a story by this author, one character achieves masculinity by shooting a lion right before he is shot by his wife; that story features a triangle between Margot, Wilson, and Francis Macomber. His works often feature the theme of "nada" and follow the iceberg theory in omitting detail. He created a character who escapes the battle police and falls in love with Catherine Barkley, and he quoted Gertrude Stein on the Lost Generation for one novel's epitaph. For 10 points, name this writer who created Frederic Henry and Jake Barnes in A Farewell to Arms and The Sun Also Rises.

SOLUTION: Literature

PROBLEM: This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.

SOLUTION: Science

PROBLEM: Its Mukai variety is useful in defining abelian varieties, and the essentially identical Plancherel theorem and Parsevals theorem show that it is unitary and applying one of these to a Dirac comb will result in another Dirac comb. It is integral to the Nyquist-Shannon sampling theorem, and both Bluestein's algorithm and Rader's algorithm compute a form of it by transforming it into a convolution, while runtime big-O of n log n for one variety of them is achieved by recursively breaking it down into smaller ones, a technique known as the Cooley-Tukey algorithm. Commonly used in signal and image processing, FTP, name this mathematical operation that breaks a function down into a spectrum of its component sinusoidal frequencies.
