instruction:
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.
question:
The person on the left side of this painting, wearing an apron and sailor trousers, is next to a kneeling man with green trousers, a black suit, and black top hat. That man's knee is on the same cobblestones as the hands of the person with a blue shirt and red bandana who is looking up. The right side of this work shows a student with a cartridge pouch carried in a sling over his shoulder and with a gun in each hand. There are also wounded bodies lying on the ground, and the central figure has a loose yellow dress and is holding up a flag. Name this work set during the July Revolution showing the tricolor flag of France, painted by Eugene Delacroix [deh-lah-kwah].
answer:
Fine Arts


question:
One work by this composer features text from speeches of a certain American president. A highly patriotic work by this man was later reworked into his final symphony, his third. This composer of Lincoln Portrait wrote the score for a ballet which included sections such as "Saturday Night Waltz" and the "Hoe Down." This composer was commissioned by Martha Graham to write a ballet set in Pennsylvania that includes variations on the Shaker hymn Simple Gifts. For 10 points, identify this composer of Rodeo and Appalachian Spring.
answer:
Fine Arts


question:
The collisionless Boltzman equation is often referred to as this, and it can be used to extend the Runge-Gross theorem to time-dependent ensembles. A corollary of this result is that symplectic maps of Hamiltonian functions must preserve area. Applying this theorem to the expectation value of an observable in quantum mechanics gives a result that can also be derived by finding the expection value of the Heisenberg equation of motion, known as Ehrenfest's theorem. It can be expressed as the time derivative of a density equals the negative Poisson bracket of that density and the Hamiltonian. In the ergodic formulation, this theorem predicts smooth measure invariance under Hamiltonian flow, and it is equivalent to the Second Law of Thermodynamics. For 10 points, name this theorem in statistical mechanics which states the density of points is constant along a phase space trajectory with time.
