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]: A ubiquitin ligase that marks specific proteins which the 26S proteasome breaks down is known as its (*) promoting complex, and in plants, the step immediately following it features vesicles moving along the phragmoplast. The step preceding it is ended by inactivation of cyclin dependent kinases, and the kinetochore fibers become shorter during this step. Chromatid pairs separate into identical chromosomes, which are subsequently pulled to the poles by the spindle fibers. FTP, identify this step of cell division that follows metaphase.
[EX A]: Science

[EX Q]: Works during this man's Serialist period include the choral work The Dove Descending Breaks the Air and Threni along with a piece commemorating the poet Dylan Thomas. Early in his career he wrote songs such as "The Fairy's Kiss" and The Faun and the Shepherdess along with a popular concerto for orchestra known as Fireworks. His operatic works include the one-act work Rossignol and an opera about Nick Shadow with a libretto by W.H. Auden, The Rake's Progress, but he is better known for his Psalm Symphony and ballets like Petruschka. FTP, name this Russian composer of The Rite of Spring and The Firebird.
[EX A]: Fine Arts

[EX Q]: This universal property of all spinless boson systems can be derived exactly for all charged scalar fields at any temperature. This property is most easily observed in symmetric electronic structures such as ionic crystals. Materials with this property do not fit into the assumptions of Earnshaws theorem, as they have negative susceptibility. Bismuth has the highest elemental value for this property, and superconductors demonstrate the perfect variety of this property when they expel magnetic fields. For ten points, identify this type of magnetism employed in a namesake type of levitation and distinguished from paramagnetism.
