TASK DEFINITION: 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.
PROBLEM: One character in this novel receives news of her brother's death from her father while he uses a lathe. This novel's protagonist develops a friendship with Platon Karataev, a peasant he meets in a prisoner of war camp. Another character, Nikolai, is led to financial ruin after(*) losing 40,000 roubles to Dolokov. Andrei Bolkonski is wounded in battle following the end of his engagement to Natasha Rostova, who falls in love with the novel's protagonist. For 10 points, name this gargantuan Leo Tolstoy novel about Pierre Bezukhov set during the Napoleonic Wars.

SOLUTION: Literature

PROBLEM: The yield of these compounds can be increased through ball milling of some of their components, and one mode of operation of these compounds proceeds through a mechanism called enantiomorphic site control. A process for the operation of these compounds that proceeds through migratory insertions and obeys the "principle of least nuclear motions" was developed by Cossee and Arlman. Compounds such bis(cyclopentadienyl)titanium chloride and bis(indenyl)zirconium dichloride, known as metallocenes, have been developed as an alternative to the traditional compounds of this type. Those traditional initiators include vanadium trichloride and triethylaluminum, and the product of the application of these compounds to alkenes can result in syndiotactic, isotactic, or atactic products. For ten points, identify these stereoselective compounds used to initiate polymerization, named for a German and an Italian chemist.

SOLUTION: Science

PROBLEM: In flow cytometry, these molecules bind to fluorophores to differentiate test cells, and HRP is bound to them for use in another process. Kohler and Milstein discovered that myeloma cells can produce the monoclonal variety of these molecules. Three layers of these are used in the "sandwich" variety of the ELISA technique, and these proteins exhibit disulfide bonds between their two heavy and light chains to form a Y-shaped structure. The type of these molecules which attack A and B blood groups is known as Immunoglobulin M. Released by plasma B cells, for 10 points, name these proteins produced by the immune system which each tag a unique antigen.
