Input: Bird migration
Some large broad-winged birds rely on thermal columns of rising hot air to enable them to soar. These include many birds of prey such as vultures, eagles, and buzzards, but also storks. These birds migrate in the daytime. Migratory species in these groups have great difficulty crossing large bodies of water, since thermals only form over land, and these birds cannot maintain active flight for long distances. Mediterranean and other seas present a major obstacle to soaring birds, which must cross at the narrowest points. Massive numbers of large raptors and storks pass through areas such as the Strait of Messina, Gibraltar, Falsterbo, and the Bosphorus at migration times. More common species, such as the European honey buzzard Pernis apivorus, can be counted in hundreds of thousands in autumn. Other barriers, such as mountain ranges, can also cause funnelling, particularly of large diurnal migrants. This is a notable factor in the Central American migratory bottleneck. Batumi bottleneck in the Caucasus is one of the heaviest migratory funnels on earth. Avoiding flying over the Black Sea surface and across high mountains, hundreds of thousands of soaring birds funnel through an area around the city of Batumi, Georgia. Birds of prey such as honey buzzards which migrate using thermals lose only 10 to 20% of their weight during migration, which may explain why they forage less during migration than do smaller birds of prey with more active flight such as falcons, hawks and harriers.

How much of their body weight do honey buzzards lose during migration?
Output: 10 to 20%

Input: Department store
Arnold, Constable was the first American department store. It was founded in 1825 by Aaron Arnold (1794?-1876), an emigrant from Great Britain, as a small dry goods store on Pine Street in New York City. In 1857 the store moved into a five-story white marble dry goods palace known as the Marble House. During the Civil War Arnold, Constable was one of the first stores to issue charge bills of credit to its customers each month instead of on a bi-annual basis. Recognized as an emporium for high-quality fashions, the store soon outgrew the Marble House and erected a cast-iron building on Broadway and Nineteenth Street in 1869; this “Palace of Trade” expanded over the years until it was necessary to move into a larger space in 1914. In 1925, Arnold, Constable merged with Stewart & Company and expanded into the suburbs, first with a 1937 store in New Rochelle, New York and later in Hempstead and Manhasset on Long Island, and in New Jersey. Financial problems led to bankruptcy in 1975.
