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.

[EX Q]: The theory in which these particles appear is an SU(3) gauge theory, and particles composed only of them are predicted to exist, but the only candidate known, f(1710), decays too quickly into K-mesons. During the first ten microseconds after the Big Bang, the state of matter where hadrons are decomposed that was said to have formed is known as a plasma of quarks and these particles. A vector gauge boson of spin 1, they have only two polarization states and have eight independent types, and although their exchange results in a change of color, the quarks maintains the balance of color. Carriers of the strong nuclear force, these are, FTP, which subatomic particles that cause quarks to interact and thus the binding of protons and neutrons in nuclei

[EX Q]: This man had a brother named Johann Michael, who was also a notable composer. This composer's two oratorios are called The Seasons and The Creation. This composer's string quartets are compiled into groups such as "Erdody" and "Sun," and because he wrote many of them, he is often called the "Father of String Quartets."  This composer wrote over 100 symphonies, including ones nicknamed "Clock," "Surprise," and "Farewell."  For 10 points, name this Austrian composer often called the "Father of the Symphony."

[EX Q]: The diagonal elements of the coupling matrix in an orthonormal n-energy-state system are fully perturbed matrix elements of this object. Adding first-order relativistic corrections to the momentum naturally creates the fine-structure version of this operator, since it is equal to one over the twice the system mass times the inner product of the momentum operator with itself, plus the potential operator. FTP, identify this operator, the operation of which on the wave function is equal to operation of the energy operator on the wave function according to the Schrdinger equation, that is symbolized "h-hat" and that is named for a 19th Century Irish mathematician.
