The problem: Answer a question about this article:
Ninety-five percent of bird species are socially monogamous. These species pair for at least the length of the breeding season orin some casesfor 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.
What is extra-pair copulation?
****
The answer: infidelity

Problem: Please answer a question about the following article about Airport:
On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.
What may low-traffic airports use to save electricity and staffing costs?
A: pilot controlled lighting

As economic and demographic methods were applied to the study of history, the trend was increasingly to see the late Middle Ages as a period of recession and crisis. Belgian historian Henri Pirenne continued the subdivision of Early, High, and Late Middle Ages in the years around World War I. Yet it was his Dutch colleague, Johan Huizinga, who was primarily responsible for popularising the pessimistic view of the Late Middle Ages, with his book The Autumn of the Middle Ages (1919). To Huizinga, whose research focused on France and the Low Countries rather than Italy, despair and decline were the main themes, not rebirth.

What was the nationality of historian Henri Pirenne?
Answer: Belgian

Problem: Some Christian writers considered the possibility that pagan commentators may have mentioned this event, mistaking it for a solar eclipse - although this would have been impossible during the Passover, which takes place at the full moon. Christian traveller and historian Sextus Julius Africanus and Christian theologian Origen refer to Greek historian Phlegon, who lived in the 2nd century AD, as having written "with regard to the eclipse in the time of Tiberius Caesar, in whose reign Jesus appears to have been crucified, and the great earthquakes which then took place"
As what was the event mistaken by some pagans?
The answer is the following: a solar eclipse

Beyond combat flight crew personnel, perhaps the most dangerous USAF jobs are Explosive Ordnance Disposal (EOD), Combat rescue officer, Pararescue, Security Forces, Combat Control, Combat Weather, Tactical Air Control Party, and AFOSI agents, who deploy with infantry and special operations units who disarm bombs, rescue downed or isolated personnel, call in air strikes and set up landing zones in forward locations. Most of these are enlisted positions augmented by a smaller number of commissioned officers. Other career fields that have seen increasing exposure to combat include civil engineers, vehicle operators, and Air Force Office of Special Investigations (AFOSI) personnel.
What do some of these special missions in the USAF who deploy with the infantry do?
rescue downed or isolated personnel

Here is a question about this article: Dvaita Vedanta is a dualistic interpretation of the Vedas, espouses dualism by theorizing the existence of two separate realities. The first and the only independent reality, states the Dvaita school, is that of Vishnu or Brahman. Vishnu is the supreme Self, in a manner similar to monotheistic God in other major religions. The distinguishing factor of Dvaita philosophy, as opposed to monistic Advaita Vedanta, is that God takes on a personal role and is seen as a real eternal entity that governs and controls the universe. Like Vishishtadvaita Vedanta subschool, Dvaita philosophy also embraced Vaishnavism, with the metaphysical concept of Brahman in the Vedas identified with Vishnu and the one and only Supreme Being. However, unlike Vishishtadvaita which envisions ultimate qualified nondualism, the dualism of Dvaita was permanent.
What is the answer to this question: To what entity is the Vedanta Vishnu similar in other religions?
****
So...
monotheistic God
