Problem: Question: "Which was the first year that a presidential debate was held at the mentioned university during the 21 century?"  Context: "Washington University has been selected by the Commission on Presidential Debates to host more presidential and vice-presidential debates than any other institution in history. United States presidential election debates were held at the Washington University Athletic Complex in 1992, 2000, 2004, and 2016. A presidential debate was planned to occur in 1996, but owing to scheduling difficulties between the candidates, the debate was canceled. The university hosted the only 2008 vice presidential debate, between Republican Sarah Palin and Democrat Joe Biden, on October 2, 2008, also at the Washington University Athletic Complex."  Answer:

A: 2000


Problem: Question: "Even though considered monogamous, what do birds sometimes commit?"  Context: "Ninety-five percent of bird species are socially monogamous. These species pair for at least the length of the breeding season or—in some cases—for several years or until the death of one mate. Monogamy allows for both paternal care and biparental care, which is especially important for species in which females require males' assistance for successful brood-rearing. Among many socially monogamous species, extra-pair copulation (infidelity) is common. Such behaviour typically occurs between dominant males and females paired with subordinate males, but may also be the result of forced copulation in ducks and other anatids. Female birds have sperm storage mechanisms that allow sperm from males to remain viable long after copulation, a hundred days in some species. Sperm from multiple males may compete through this mechanism. For females, possible benefits of extra-pair copulation include getting better genes for her offspring and insuring against the possibility of infertility in her mate. Males of species that engage in extra-pair copulations will closely guard their mates to ensure the parentage of the offspring that they raise."  Answer:

A: infidelity


Problem: Question: "what is Porto?"  Context: "Tourist hotspots in Portugal are Lisbon, Algarve, Madeira, Porto and the city of Coimbra, also, between 4-5 million religious pilgrims visit Fátima each year, where apparitions of the Blessed Virgin Mary to three shepherd children reportedly took place in 1917. The Sanctuary of Fátima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. Lisbon is the 16th European city which attracts the most tourists (with seven million tourists occupying the city's hotels in 2006, a number that grew 11.8% compared to previous year). Lisbon in recent years surpassed the Algarve as the leading tourist region in Portugal. Porto and Northern Portugal, especially the urban areas north of Douro River valley, was the tourist destination which grew most (11.9%) in 2006, surpassing Madeira (in 2010), as the third most visited destination.[citation needed]"  Answer:

A: Tourist hotspots


Problem: Question: "What is another word for methods?"  Context: "Mill's empiricism thus held that knowledge of any kind is not from direct experience but an inductive inference from direct experience. The problems other philosophers have had with Mill's position center around the following issues: Firstly, Mill's formulation encounters difficulty when it describes what direct experience is by differentiating only between actual and possible sensations. This misses some key discussion concerning conditions under which such "groups of permanent possibilities of sensation" might exist in the first place. Berkeley put God in that gap; the phenomenalists, including Mill, essentially left the question unanswered. In the end, lacking an acknowledgement of an aspect of "reality" that goes beyond mere "possibilities of sensation", such a position leads to a version of subjective idealism. Questions of how floor beams continue to support a floor while unobserved, how trees continue to grow while unobserved and untouched by human hands, etc., remain unanswered, and perhaps unanswerable in these terms. Secondly, Mill's formulation leaves open the unsettling possibility that the "gap-filling entities are purely possibilities and not actualities at all". Thirdly, Mill's position, by calling mathematics merely another species of inductive inference, misapprehends mathematics. It fails to fully consider the structure and method of mathematical science, the products of which are arrived at through an internally consistent deductive set of procedures which do not, either today or at the time Mill wrote, fall under the agreed meaning of induction."  Answer:

A:
procedures
