instruction:
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.
question:
Vietnamese national hero Le Loi defended his country against this dynasty's forces. The Fish Scale Records were used to calculate taxes by this dynasty's founder, the Hongwu Emperor. This dynasty's Yong-le Emperor ordered the construction of Beijing's Forbidden City. The (*) Yuan Dynasty fell during the Red Turban Rebellion, which brought this dynasty to power. Zheng He was a eunuch admiral who explored under this dynasty's banner. For 10 points, name this Chinese dynasty that began in the 1300s and was renowned for its porcelain.
answer:
History


question:
This reaction is combined with an aldol condensation to produce cyclohexenones in a process named for Robinson, and a variation of this uses silyl ethers and titanium tetrachloride, in a reaction named also for Mukaiyama. In a process analogous to this reaction, performed with simple ketones, the equilbrium is shifted towards the reagents, unlike in the Claisen and aldol condensations, necessitating the use of an enolate in conjugate addition to produce the 1,4-addition. For 10 points, what is this reaction named for an American chemist, which consists of the addition of a carbanion to an alpha, beta unsaturated carbonyl
answer:
Science


question:
Henry Kister wrote numerous books on the design and operation of this type of process. It is possible to adjust equilibrium behavior to observed behavior in this type of process using an efficiency calculation named after Murphree, and Hengstebeck diagrams can be used for troubleshooting when multiple components are present. Stanislaw Wasylkiewicz developed a model using bifurcation theory to determine effectiveness of two sequential processes of this type running at different pressures. A one-stage related process is called a (*) flash unit, and the upper portion of columns where this process occurs is known as the rectifying section. When multiple components are present the bulk separation in this process is targeted between a light and a heavy key. It's not adsorption, but its pressure-swing form or addition of entrainers can be used to break azeotropes. For 10 points, name this technique for separating components by volatility, often conducted in multi-trayed columns.
answer:
