Context and question: 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.

Context and question: The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snježana Kordić has been leading an academic discussion on that issue in the Croatian journal Književna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandić states: "During the last ten years, it has been the longest, the most serious and most acrid discussion (…) in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.
Is it the majority or minority opinion that two different standard languages existed and overlapped at some historical point?
Answer:
majority
