question:
Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors.
answer:
What percentage increase in flight distance will often be adaptive?


question:
Cork was originally a monastic settlement, reputedly founded by Saint Finbarr in the 6th century. Cork achieved an urban character at some point between 915 and 922 when Norseman (Viking) settlers founded a trading port. It has been proposed that, like Dublin, Cork was an important trading centre in the global Scandinavian trade network. The ecclesiastical settlement continued alongside the Viking longphort, with the two developing a type of symbiotic relationship; the Norsemen providing otherwise unobtainable trade goods for the monastery, and perhaps also military aid.
answer:
Who was thought to have founded Cork?


question:
The Qing organization of provinces was based on the fifteen administrative units set up by the Ming dynasty, later made into eighteen provinces by splitting for example, Huguang into Hubei and Hunan provinces. The provincial bureaucracy continued the Yuan and Ming practice of three parallel lines, civil, military, and censorate, or surveillance. Each province was administered by a governor (巡撫, xunfu) and a provincial military commander (提督, tidu). Below the province were prefectures (府, fu) operating under a prefect (知府, zhīfǔ), followed by subprefectures under a subprefect. The lowest unit was the county, overseen by a county magistrate. The eighteen provinces are also known as "China proper". The position of viceroy or governor-general (總督, zongdu) was the highest rank in the provincial administration. There were eight regional viceroys in China proper, each usually took charge of two or three provinces. The Viceroy of Zhili, who was responsible for the area surrounding the capital Beijing, is usually considered as the most honorable and powerful viceroy among the eight.
answer:
What two provinces were formed from Huguang?
