Answer: Zero
The Amazon has the largest drainage basin in the world and discharges about 209,000 cubic metres per second or 55,000,000 US gal/second which is greater than the next seven largest rivers in the world combined. This represents 20% of the global ocean discharge from rivers.
The Amazon River is in the northern half of South America, flowing from west to east. It originates in the Andes Mountains in Peru then travels through Ecuador, Colombia, Venezuela, Bolivia, and Brazil before reaching the Atlantic Ocean 6400 kilometres or 4000 miles (approximately) later.
There are no capital cities on the river for two reasons: The river is actually a huge flood plain and along most of its length are protected conservation areas to preserve fauna and flora.
There are three major cities on the river: Iqitos in Peru, Manhaus in the centre of Brazil and Belem on the river's delta near the Atlantic coast. It is possible to reach Manhaus, a city of two million people, by road but it is an 11 hour bus journey from Boa Vista in northern Brazil or 36 hours from Venezuela. Iquitos, a city of nearly half a million, can only be reached by river or plane.
Another fascinating piece of trivia: Not one bridge crosses the Amazon in its entire 6400 km length. While any such bridge would be very long there are no plans to build one as the population around the river is very small and ferries are all that is required.

The Volga is the main waterway in this great nation. Its importance to the Russian people stretches far back into the mists of time, leading to this river being given the affectionate title "Mother Volga". It contains many locks which were built to bypass reservoirs and dams. Trade is important upstream and downstream on this giant waterway, with building materials, fish, and grain ferried to its upper regions, and lumber shipped downstream.

The Snake begins in Yellowstone National Park in Wyoming, USA, then flows through Oregon, Idaho and Washington. With steep mountains and deep canyons, it is part of the largest North American river system to empty, eventually, into the Pacific Ocean. Shoshone and Nez Perce peoples have lived along this river since prehistoric times. In its best years it ran millions of salmon.

The third was launched as HMS Duddon but was given to Canada in 1944 and renamed HMCS Ribble. The last one was sold to Brazil in 1995 and recommissioned as H-37 Garnier Sampaio. The "African Queen" was built by Lytham Shipbuilding and Engineering Limited in 1912.

The River Irwell is 39 miles long and separates Manchester and Salford city centres, yet flows close to the heart of Manchester city centre. The "Big Ditch" is a term used to describe the Manchester Ship Canal, which helped Salford and Manchester become a major port in the late 19th century. Despite its polluted past the River Irwell has been cleaned up somewhat and is stocked with fish in places. It is also the river where Manchester and Salford Universities have their boat race.

Any body of water feeding the Great Lakes drains into the St. Lawrence, but the Lake of the Woods (mostly in Ontario and Minnesota) drains, via the Winnipeg River, into Lake Winnipeg, and thus into the Hudson Bay watershed. Lac St.-Jean (in Quebec), drains into the Saguenay River, a tributary of the St. Lawrence.

Answer: Manaus
Manaus, the capital of the Brazilian state of Amazonas, has a population of about 2 million. Because of its unique location, it is generally reached by boat or plane, though in recent years roads have been built that pass close to the city. Manaus was founded in the late 17th century as a fort named Fort de São José da Barra do Rio Negro, then elevated to town status in 1832 with the name of Manaus (after the indigenous Manaós people). In the late 19th century, the rubber boom made Manaus the richest city in South America, nicknamed the Paris of the Tropics for its sophisticated and extravagant lifestyle - which included the introduction of electricity and the building of an opera house, the Teatro Amazonas. When the boom ended, the city underwent an abrupt decline, which lasted for most of the 20th century. In the 1960s, the introduction of a free trade zone and the opening of new roads encouraged the regrowth of the city's population. Now Manaus is one of Brazil's largest cities, with a thriving tourist industry that makes the most of the city's unique environment and culture. The Rio Negro ("black river") gets its name from the tannins from decaying vegetal matter that stain its water a dark brown colour; it is the Amazon's largest tributary (2,250 km/1,400 mi), and the one of the world's ten largest rivers in term of discharge. Solimões is the name given to the upper part of the Amazon River in Brazilian Portuguese.
The three remaining options are all major South American cities, two of them (Buenos Aires and Lima) also national capitals.

Answer: Tay
As well as being the longest river in Scotland at 188 km (117 miles), the Tay is the seventh longest river in the UK. The Tay flows across the Highlands from the slopes of Ben Lui in western Scotland. After flowing through three lochs, it travels through the centre of Scotland at Strathray, then flows through Perth in the southeast, and then to its mouth at the Firth of Tay. By volume, it is the largest river in the UK, its catchment being about 5,200 sq km (2,000 square miles).
The Tay has a large population of Atlantic salmon, freshwater pearl mussels and Eurasian otters. Anglers come from all over the world to fish for Atlantic salmon. The British record for the largest salmon ever caught by rod weighed 64 lbs, and was caught in the Tay River in 1922. The Tay has many tributaries that are also renowned for salmon fishing.

The Congo is almost 3,000 miles long. Interestingly, it is the deepest river in the world, reaching depths of 750 feet. The area of Africa through which it makes its long journey badly lacks roads and railways, apart from the very minimum of these. The Congo then is the lifeline that holds the economy together. Products that are ferried along this river include copper, palm oil, sugar, coffee and cotton. The Congo is also a vital source of produced electricity. Astonishingly, by the turn of the 21st century, it possessed forty hydropower plants along its journey, with more planned. These produce thirteen percent of the world's entire hydropower generated electricity. With the potential for many more to be constructed, the very real possibility exists for the Congo to become a leading trader in this necessity of the modern world.

The history of this mighty river is fascinating. Its giant floods, its massive change of direction, its enormous cost of life - it's almost as though this massive waterway is a country in its own right. Just one little snippet in this regard: such is the amount of sediment deposited in some parts of the river, the resulting build up of the same actually causes the river to flow ABOVE the level of the lands it flows through. For thousands of years this stupendous river has seen the enormous development of agricultural products. This allowed the increasing population along its banks to store and trade in these crops. With this then came the craftsmen and the artisans to add their products to an ever-growing trade along the river. Cites built around this economy grew from this. Today the river is an important source of hydroelectricity as well.
