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: Seas of calcite predominate during times of low concentration of this element. The NIMS probe discovered that Ganymede has a sulfate of this element, which is also used to treat eclampsia. Its molten form is used to make metallic titanium in the Kroll process. The active site of rubisco contains a carbamylated lysine attached to an ion of this element. Its cationic form is used to stabilize the product of PCR, and it is also prevalent in certain reagents in a Schlenck equilibrium. It is found in Grignard reagents as well as coordinated to the porphyrin ring of chlorophyll. For 10 points, name this element with atomic number 12 and symbol Mg.
Example Output: Science

Example Input: This pathway is inhibited by a deficiency that causes a precursor molecule to be lacking, known as Tauri's Disease, which is a deficiency of the Phosphofructokinase enzyme. A reverse of this reaction is used by bacteria to synthesize carbon compounds from CO2 and water. Its third step sees cis Aconitate attacked by Aconitase and hydrated to release water. Its ninth step sees an addition reaction between Fumarate and the Fumarase enzyme. During its first turn, it produces one GTP, three NADH, one FADH2, and two CO2. FTP, name this pathway, occurring directly before the electron transport chain in cellular respiration, also known as the Citric Acid Cycle.
Example Output: Science

Example Input: Gaunt coefficients are used to represent scalar coupling when it is lost from cross differentiation, and Clebsch-Gordan coefficients are used for the general addition of this quantity. A paradox named for Feynman involving a coil of wire, through which a current flows, can be resolved by noting the existence of this quantity for static electromagnetic fields. Magnetic field lines reduce this parameter in the Blandford-Znajek process, and when this value is equal to zero, the space-time metric reduces to the Reissner-Nordstrom solutions. Noether's theorem states that if the Lagrangian function is independent of the angle of measurement, then this quantity will be conserved. It can be stated as Iota times Omega, and its time derivative is equal to torque. For 10 points, name this vector quantity that for rotating systems is the product of the moment of inertia and angular velocity.
