This basin encompasses 7,000,000 km (2,700,000 sq mi), of which 5,500,000 km (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations contain ``Amazonas'' in their names. The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.
 Question: the amazon rainforest is the largest rainforest in the world Context: The country's standing as the largest Caribbean economy, second-largest country in terms of population and land mass, with large bilateral trade with the United States, and its proximity to the United States and other smaller Caribbean nations make the Dominican Republic an important partner in hemispheric affairs. The Embassy estimates that 100,000 U.S. citizens live in the Dominican Republic; many of whom are dual nationals. An important element of the relationship between the two countries is the fact that more than 1 million individuals of Dominican origin reside in the United States, most of them in the metropolitan Northeast and some in Florida.
 Question: is the dominican republic a part of the united states Context: Angel Falls (Spanish: Salto Ángel; Pemon language: Kerepakupai Meru meaning ``waterfall of the deepest place'', or Parakupá Vená, meaning ``the fall from the highest point'') is a waterfall in Venezuela. It is the world's highest uninterrupted waterfall, with a height of 979 meters (3,212 ft) and a plunge of 807 meters (2,648 ft). The waterfall drops over the edge of the Auyán-tepui mountain in the Canaima National Park (Spanish: Parque Nacional Canaima), a UNESCO World Heritage site in the Gran Sabana region of Bolívar State. The height figure 979 metres (3,212 ft) mostly consists of the main plunge but also includes about 400 metres (0.25 mi) of sloped cascade and rapids below the drop and a 30-metre (98 ft) high plunge downstream of the talus rapids.
 Question: salto ángel is the tallest waterfall in the world Context: The black eagle is a large but slender eagle, at about 65 to 81 cm (26 to 32 in) in length and 148 to 182 cm (4 ft 10 in to 6 ft 0 in) in wingspan. Despite its large appearance (it is one of the largest eagles in its range), known weights are relatively modest, at between 1,000 and 1,600 g (2.2 and 3.5 lb), about half the weight of the partially sympatric mountain hawk-eagle, the latter being of a similar total length. Adults have all-black plumage, with a yellow bill base (cere) and feet. The wings are long and pinched in at the innermost primaries giving a distinctive shape. The tail shows faint barring and upper tail covers paler. When perched the wing tips reach till or exceed the tail tip. The wings are held in a shallow V (wings just above the horizontal plane) in flight. Seen on hot afternoons, scouring the treetops for a nest to maraud, this bird is easily spotted by its jet black colour, large size, and a 'characteristic' slow flight, sometimes just above the canopy.
