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: This work cites Proudhon's Philosophy of Poverty as an example of a form of a philosophy to which it claims economists, philanthropists, and humanitarians belong. Its second section advocates a ten-point program which calls for the establishment of industrial armies as well as free education for all children in public schools. That section follows one which examines the history of the (*) bourgeoisie and the proletarians and claims that the history of society is a history of class warfare. For ten points, name this work authored by Friedrich Engels and Karl Marx, which discusses how the problems of capitalism would be solved by adopting socialism and eventually the title ideology.

SOLUTION: Social Science

PROBLEM: Elliott Antokoletz argues that a certain treaty inspired this composer's "expansion in range" technique in his third string quartet, which begins with sections called "prima parte" and "seconda parte" and introduced his namesake pizzicato. He wrote a work based on a colinda in which nine sons are turned into stags, while another piece opens with a group of "Unison Melodies" and ends with six pieces dedicated to Harriet Cohen. This composer of Cantata Profana wrote a work parodying Shostakovich's "invasion" theme in the "intermezzo interrotto" fourth movement and wrote a collection of 153 instructional piano pieces titled Mikrokosmos. He wrote an opera ending when Judith opens the seventh door of the title location to uncover the three former wives of her husband. For 10 points, name this composer of Concerto for Orchestra and Duke Bluebeard's Castle who collected Hungarian folk songs.
