Bird migration is primarily, but not entirely, a Northern Hemisphere phenomenon. This is because land birds in high northern latitudes, where food becomes scarce in winter, leave for areas further south (including the Southern Hemisphere) to overwinter, and because the continental landmass is much larger in the Northern Hemisphere. In contrast, among (pelagic) seabirds, species of the Southern Hemisphere are more likely to migrate. This is because there is a large area of ocean in the Southern Hemisphere, and more islands suitable for seabirds to nest.
Which species of seabirds are more likely to migrate?
species of the Southern Hemisphere

Input: Article: Jefferson and James Madison's conceptions of separation have long been debated. Jefferson refused to issue Proclamations of Thanksgiving sent to him by Congress during his presidency, though he did issue a Thanksgiving and Prayer proclamation as Governor of Virginia. Madison issued four religious proclamations while President, but vetoed two bills on the grounds they violated the first amendment. On the other hand, both Jefferson and Madison attended religious services at the Capitol. Years before the ratification of the Constitution, Madison contended "Because if Religion be exempt from the authority of the Society at large, still less can it be subject to that of the Legislative Body." After retiring from the presidency, Madison wrote of "total separation of the church from the state." " "Strongly guarded as is the separation between Religion & Govt in the Constitution of the United States," Madison wrote, and he declared, "practical distinction between Religion and Civil Government is essential to the purity of both, and as guaranteed by the Constitution of the United States." In a letter to Edward Livingston Madison further expanded, "We are teaching the world the great truth that Govts. do better without Kings & Nobles than with them. The merit will be doubled by the other lesson that Religion flourishes in greater purity, without than with the aid of Govt." Madison's original draft of the Bill of Rights had included provisions binding the States, as well as the Federal Government, from an establishment of religion, but the House did not pass them.[citation needed]

Now answer this question: What is essential to the purity of both religion and civil government?

Output: practical distinction


Article: Even so, the decision by OKL to support the strategy in Directive 23 was instigated by two considerations, both of which had little to do with wanting to destroy Britain's sea communications in conjunction with the Kriegsmarine. First, the difficulty in estimating the impact of bombing upon war production was becoming apparent, and second, the conclusion British morale was unlikely to break led OKL to adopt the naval option. The indifference displayed by OKL to Directive 23 was perhaps best demonstrated in operational directives which diluted its effect. They emphasised the core strategic interest was attacking ports but they insisted in maintaining pressure, or diverting strength, onto industries building aircraft, anti-aircraft guns, and explosives. Other targets would be considered if the primary ones could not be attacked because of weather conditions.

Question: When would other targets be considered available?
Ans: if the primary ones could not be attacked because of weather conditions


Here is a question about this article: Town Quay is the original public quay, and dates from the 13th century. Today's Eastern Docks were created in the 1830s by land reclamation of the mud flats between the Itchen & Test estuaries. The Western Docks date from the 1930s when the Southern Railway Company commissioned a major land reclamation and dredging programme. Most of the material used for reclamation came from dredging of Southampton Water, to ensure that the port can continue to handle large ships.
What is the answer to this question: In what decade were the Eastern Docks that can be seen today created?
****
So... 1830s


Article: In 1849, Horne's began operations and soon became a leading Pittsburgh department store. In 1879, it opened a seven-story landmark which was the first department store in the city's downtown. In 1972, Associated Dry Goods acquired Horne's, and ADG expanded operations of Horne's to several stores in suburban malls throughout the Pittsburgh region as well as in Erie, Pennsylvania and Northeast Ohio. In December 1986, Horne's was acquired by a local investor group following ADG's acquisition by May Department Stores. By 1994, Federated Department Stores acquired the remaining ten Horne's stores and merged them with its Lazarus division, completely ceasing all operations of any store under the Horne's name.

Question: In what year did Horne began doing business?
Ans:
1849
