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: The relationship between temperature and this quantity is given by the Steinhart-Hart equation. Tunnel diodes have a negative value for this quantity, whose changes are measured by the most common type of strain gauge. The proximity and skin effects cause increases in this quantity with increasing frequency. The time constant tau is equal to indudctance divided by this quantity in an RL circuit. An unknown value of this quantity can be determined with a Wheatstone bridge. This quantity is the real part of impedance in AC circuits, and it is equal to voltage divided by current. For 10 points, name this opposition to the flow of current that is measured in ohms.
Example Output: Science

Example Input: Chan and Kim at Penn State discovered that crystals can display this phenomenon. One instance of this phenomenon is distinguished by either an A or B phase, and is anisotropic. Some materials that exhibit this phenomenon display a 30 nm Rollin film, and their movement sometimes displays the Onnes Effect. Landau theorized that quantum sound waves are responsible for this effect, which he posited occurs below the lambda point. For 10 points, name this property notably displayed by helium, when a liquid or gas displays no resistance to flow.
Example Output: Science

Example Input: In nature, this element is prevalent in gypsum and dolomite, as well as a namesake birefringent mineral that marks the 3 on Mohs hardness scale. Its presence in biological cells can lead to the formation of inositol tri-phosphate and di-acyl-glycerol, and its influx into axons causes release of neuro-transmitters. It is stored in the sarcoplasmic reticulum of muscle cells, where it aids contraction by binding to troponin. For 10 points, name this element that needs vitamin D to be absorbed, which joins with phosphate to form the mineral basis of bone and is symbolized Ca.
