PROBLEM: Harnik et al. argue against the anthropic principle by proposing a universe that lacks this. One instance of this interaction is modeled with a unitary matrix that includes three mixing angles and a complex phase that models CP violation. A vector minus axial Lagrangian for this force leads to maximal parity violation, making this force only affect left-handed particles. This force is responsible for quark flavor changing, was unified with electromagnetism by Glashow, Weinberg, and Salaam, and is transmitted by the massive W and Z bosons. For 10 points, name this fundamental force involved in radioactive decays.

SOLUTION: Science

PROBLEM: One member of this phylum, Strongylocentrotus purpuratus, is often used to study developmental processes, and another, Pisaster ochraceus, is an example of a keystone species. Most members of this phylum have pedicellariae that possess three jaws, and some have a chewing apparatus known as Aristotle's lantern. Members of class Asteroidea of this phylum have an ambulacral groove, and the madreporite is the entrance to their water vascular system that includes tube feet. FTP name this phylum whose "spiny skinned" members have radial symmetry and include sand dollars, sea urchins, and sea stars.

SOLUTION: Social Science

PROBLEM: This man's troops donned surplus slaughterhouse tunics while fighting against Juan Manuel de Rosas. In another campaign, he won at Calatafimi after landing at Marsala. He was ordered not to attack Trentino, but he earlier defeated the Neapolitans at the Volturno River. This leader of the Expedition of the Thousand allied with the prime minister of Sardinia-Piedmont, the Count di Cavour, to install Victor Emmanuel II as king. For 10 points, name this leader of the Red Shirts during the Risorgimento, the military leader behind Italian unification.
