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.

Q: George Meredith's bitter collection Modern Love is composed of works in a modified form of this style. Edmund Spenser's Amoretti is composed of eighty-nine of these, and Elizabeth Barrett Browning wrote a collection of them "from the Portuguese." Works in the English variety of this form can be divided into three quatrains and a couplet, and the Petrarchan type is divided into an octave and a sestet. For 10 points, name these fourteen-line poems.
