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.

Example Input: In the Corey-Bakshi-Shibata catalyst, an atom of it is attached to a pyrrole ring, an oxygen atom, and a toluene group. This element's acids are combined with amines and ketones in the Petasis reaction and in combining alkyl halides through the Suzuki coupling. Complexes containing it are called sido or arachno according to Wade's rules, and a more famous reaction using it is sometimes named for Herbert Brown. Mined from the ore Uletite, its silicate was once used in making hard glass for manufacturing laboratory equipment. For 10 points, name this element that participates in an anti-markonikov addition reaction to alkenes, with atomic number 5 and symbol B.
Example Output: Science

Example Input: In one of this mans plays, the crippled Major Magnus Muldoon turns out to be his own half-brother Albert in disguise. Another of his plays features a singer-actress who retired after seeing TV reports of a moon landing. The title character is identified as the third-string critic Puckeridge after Moon joins the action onstage in this mans The Real Inspector Hound, and Inspector Bones reveals that he is a big fan of Dotty Moore in his play Jumpers. A teenage girl named Thomasina predicts the heat death of the universe in one of his plays, and the title characters of another of his plays watch a rehearsal of The Murder of Gonzago. FTP name this author of Arcadia and Rosencrantz and Guildenstern Are Dead.
Example Output: Literature

Example Input: A 2004 paper attempted to derive superconductivity in some materials from the interactions of "small polarons" named for this effect arising from large electron-intermolecular vibration coupling in the presence of an intramolecular vibration. Certain electronic transitions in some species are unexpectedly weakly Laporte-allowed due to this effect, which also provides copper's place as highest on the high-spin Irving-Williams series. This phenomenon predicts the insulating activity of certain metal-doped fullerene species. A radical anion of cyclooctatetraene exhibits this effect. A weaker version of this effect occurs with species like scandium (I), since the t2g set does not point at any ligands. This phenomenon occurs most strongly in high spin d4, low spin d7, and d9 complexes. For 10 points, identify this phenomenon that occurs principally in octahedral geometries to prevent asymmetrically occupied orbitals from having degenerate energy levels by stretching one axis.
