Input: Article: Many bird species migrate to take advantage of global differences of seasonal temperatures, therefore optimising availability of food sources and breeding habitat. These migrations vary among the different groups. Many landbirds, shorebirds, and waterbirds undertake annual long distance migrations, usually triggered by the length of daylight as well as weather conditions. These birds are characterised by a breeding season spent in the temperate or polar regions and a non-breeding season in the tropical regions or opposite hemisphere. Before migration, birds substantially increase body fats and reserves and reduce the size of some of their organs. Migration is highly demanding energetically, particularly as birds need to cross deserts and oceans without refuelling. Landbirds have a flight range of around 2,500 km (1,600 mi) and shorebirds can fly up to 4,000 km (2,500 mi), although the bar-tailed godwit is capable of non-stop flights of up to 10,200 km (6,300 mi). Seabirds also undertake long migrations, the longest annual migration being those of sooty shearwaters, which nest in New Zealand and Chile and spend the northern summer feeding in the North Pacific off Japan, Alaska and California, an annual round trip of 64,000 km (39,800 mi). Other seabirds disperse after breeding, travelling widely but having no set migration route. Albatrosses nesting in the Southern Ocean often undertake circumpolar trips between breeding seasons.

Now answer this question: Which birds often undertake circumpolar trips between breeding seasons?

Output: Albatrosses nesting in the Southern Ocean

Input: Article: Estonia won the Eurovision Song Contest in 2001 with the song "Everybody" performed by Tanel Padar and Dave Benton. In 2002, Estonia hosted the event. Maarja-Liis Ilus has competed for Estonia on two occasions (1996 and 1997), while Eda-Ines Etti, Koit Toome and Evelin Samuel owe their popularity partly to the Eurovision Song Contest. Lenna Kuurmaa is a very popular singer in Europe[citation needed], with her band Vanilla Ninja. "Randajad" by Urban Symphony, was the first ever song in Estonian to chart in the UK, Belgium, and Switzerland.

Now answer this question: Who performed the song "Everybody"?

Output: Tanel Padar and Dave Benton

Input: Article: The loss of such a large portion of British America, at the time Britain's most populous overseas possession, is seen by some historians as the event defining the transition between the "first" and "second" empires, in which Britain shifted its attention away from the Americas to Asia, the Pacific and later Africa. Adam Smith's Wealth of Nations, published in 1776, had argued that colonies were redundant, and that free trade should replace the old mercantilist policies that had characterised the first period of colonial expansion, dating back to the protectionism of Spain and Portugal. The growth of trade between the newly independent United States and Britain after 1783 seemed to confirm Smith's view that political control was not necessary for economic success.

Now answer this question: Who argued that colonies were redundant?

Output:
Adam Smith
