Q: Slogans which became popular in this country included "we don't want to be slaves anymore" and "down with the government, down with the police." This country was home to the underground Christian organization Young Congregation, which helped instigate an event whose nine demands were issued by the Bitterfeld committee, the most influential of the workers' councils which emerged here. People in this country received boxes containing peas, flour, milk, and lard that were known as (*) Eisenhower Packages. After this country announced the New Course program, replacing Constructing Socialism, and including a ten percent increase in production quotas, workers walked out onto Stalin Alley. In this country, where the play The Plebeians Rehearse the Uprising takes place, Soviet tanks were deployed to end a 1953 popular uprising. For 10 points, identify this country which erupted into mass demonstrations against Walter Ulbricht's regime.

Q: The lemma named for this person states that if a prime number divides a product, then it divides a factor of that product. Janos Bolyai and Nikolai Lobachevsky developed a system that was notable for not following all of this person's rules. A so-called orchard is named for this person because of his algorithm for finding greatest common divisors. A book he wrote states that if a line segment intersects two lines, then the lines meet on the side of the segment where the interior angle sum is less than two right angles, the last of his five postulates. Name this mathematician whose Elements was a standard text of geometry.

Q: 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.
