Problem: Predation:

While successful predation results in a gain of energy, hunting invariably involves energetic costs as well. When hunger is not an issue, in general most predators will not seek to attack prey since the costs outweigh the benefits. For instance, a large predatory fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact that the apex predator is apparently uninterested). Surplus killing represents a deviation from this type of behaviour. The treatment of consumption in terms of cost-benefit analysis is known as optimal foraging theory, and has been quite successful in the study of animal behavior. In general, costs and benefits are considered in energy gain per unit time, though other factors are also important, such as essential nutrients that have no caloric value but are necessary for survival and health.

How is the behavior of prey fish around an uninterested predator measured?

Problem: University:

Early Modern universities initially continued the curriculum and research of the Middle Ages: natural philosophy, logic, medicine, theology, mathematics, astronomy (and astrology), law, grammar and rhetoric. Aristotle was prevalent throughout the curriculum, while medicine also depended on Galen and Arabic scholarship. The importance of humanism for changing this state-of-affairs cannot be underestimated. Once humanist professors joined the university faculty, they began to transform the study of grammar and rhetoric through the studia humanitatis. Humanist professors focused on the ability of students to write and speak with distinction, to translate and interpret classical texts, and to live honorable lives. Other scholars within the university were affected by the humanist approaches to learning and their linguistic expertise in relation to ancient texts, as well as the ideology that advocated the ultimate importance of those texts. Professors of medicine such as Niccolo Leoniceno, Thomas Linacre and William Cop were often trained in and taught from a humanist perspective as well as translated important ancient medical texts. The critical mindset imparted by humanism was imperative for changes in universities and scholarship. For instance, Andreas Vesalius was educated in a humanist fashion before producing a translation of Galen, whose ideas he verified through his own dissections. In law, Andreas Alciatus infused the Corpus Juris with a humanist perspective, while Jacques Cujas humanist writings were paramount to his reputation as a jurist. Philipp Melanchthon cited the works of Erasmus as a highly influential guide for connecting theology back to original texts, which was important for the reform at Protestant universities. Galileo Galilei, who taught at the Universities of Pisa and Padua, and Martin Luther, who taught at the University of Wittenberg (as did Melanchthon), also had humanist training. The task of the humanists was to slowly permeate the university; to increase the humanist presence in professorships and chairs, syllabi and textbooks so that published works would demonstrate the humanistic ideal of science and scholarship.

Problem: 51st state:

Residents of Puerto Rico pay U.S. federal taxes: import/export taxes, federal commodity taxes, social security taxes, therefore contributing to the American Government. Most Puerto Rico residents do not pay federal income tax but do pay federal payroll taxes (Social Security and Medicare). However, federal employees, those who do business with the federal government, Puerto Ricobased corporations that intend to send funds to the U.S. and others do pay federal income taxes. Puerto Ricans may enlist in the U.S. military. Puerto Ricans have participated in all American wars since 1898; 52 Puerto Ricans had been killed in the Iraq War and War in Afghanistan by November 2012.

How many Puerto Ricans have died in the Iraq War and War in Afghanistan?
---
A: 52

Problem: Literature:

Greek drama exemplifies the earliest form of drama of which we have substantial knowledge. Tragedy, as a dramatic genre, developed as a performance associated with religious and civic festivals, typically enacting or developing upon well-known historical or mythological themes. Tragedies generally presented very serious themes. With the advent of newer technologies, scripts written for non-stage media have been added to this form. War of the Worlds (radio) in 1938 saw the advent of literature written for radio broadcast, and many works of Drama have been adapted for film or television. Conversely, television, film, and radio literature have been adapted to printed or electronic media.

What is the genre associated with religious themes and mythological festivals?
