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 Input:
The reciprocal relationship between the eigenvalues of the mass matrix of these particles is called the "seesaw mechanism"; the larger eigenvalue may be the mass of their "sterile" variety. One phenomenon predicted by Pontecorvo involving these entities was searched for by (*) MINOS. Reines and Cowan used an aqueous cadmium chloride solution to detect them, and other detectors tend to include large volumes of material, such as Super Kamiokande. For 10 points, name these leptons, the nearly massless products of radioactive decay whose varieties include the muon and tau and which are represented by the letter nu.

Ex Output:
Science


Ex Input:
In topological insulators, one version of this effect gives rise to a defect-resistant current induced by spin-orbit coupling. In graphene, this effect is shifted by one half, giving rise to an anomalous minimum of the relevant quantity, which can allow for ballistic transport. A more complex version of it was discovered in gallium arsenide and can be explained by Laughlin quasiparticles; this is referred to as the fractional version. This effect can be understood in terms of partial filling of Landau levels and has characteristic "plateaus", and it yields numbers called filling factors. Discovered by Klaus von Klitzing when studying a two-dimensional electron gas, for 10 points, identify this effect in which conductivity in a strong magnetic field is quantized.

Ex Input:
_Before one battle, Xu You defected to this man and revealed the location of an enemy supply depot in Wuchao, which allowed this man to break a stalemate. In 2009, this man's tomb was supposedly dug up in Henan, but controversy exists on whether it is genuine or whether it belongs to one of his descendants. This man was appointed the "General who (+)_ Arranged the Army" of the Army of the Western Garden, which did not last. However, this man later built up the Qingzhou army. His domestic policies included Tun Tian System, which was directed at farmers and helped alleviate results of a locust plague. He is often depicted with a (*) white face in operatic productions, as he is often depicted as a treacherous villain. This man gained the support of Emperor Xiao after a campaign in which he captured Luoyang and defeated Dong Zhuo. This man also defeated Yuan Shao at the Battle of Guandu. In his goal of unifying China, this man was defeated by Sun Quan and Liu Bei at the Battle of Red Cliffs. For 10 points, name this warlord of the Three Kingdoms period, who laid the grounds for the kingdom of Cao Wei.
