World Geography and Capitals

Vatican City is a city-state, meaning the entire country is essentially one city. Vatican City itself is the capital, as it is both the sovereign state and its urban center. The statement that it 'does not have a capital' is therefore false.

Bujumbura is the capital of Burundi. It's the country's largest city and sits on the northeastern shore of Lake Tanganyika. The other options are capitals of different countries: Moroni (Comoros), Yamoussoukro (Cote d'Ivoire), and Nicosia (Cyprus).

N'Djamena is the capital of Chad. It's the country's largest city and sits at the confluence of the Chari and Logone rivers. The other options are capitals of different countries: Belmopan (Belize), Djibouti (Djibouti), and Santo Domingo (Dominican Republic).

Vatican City is a unique city-state where the country itself is its capital. It is the smallest independent state in the world, both in area and population, located entirely within Rome, Italy. The other options are capitals of different countries: Washington D.C. (USA), Tashkent (Uzbekistan), and Harare (Zimbabwe).

Lusaka is the capital and largest city of Zambia, located in the southern part of central Africa. It became the capital when Zambia gained independence from British rule in 1964. The other options are capitals of different countries: Pretoria (South Africa), Bern (Switzerland), and Ankara (Turkey).

Sri Jayawardenepura Kotte is the administrative capital of Sri Lanka, where the government headquarters and parliament are located. Colombo is the commercial capital and largest city, but not the administrative capital. Jaffna and Vanni are regions in Northern Sri Lanka.

Dublin, the capital of Ireland, is situated at the mouth of the River Liffey, which divides the city into north and south. The River Liffey flows through the center of Dublin and empties into Dublin Bay. The other rivers listed (Apies, Blood, Bronkhorst Spruit) are all in South Africa. The Liffey is Dublin's defining geographical feature.

Tallahassee has been the capital of Florida since 1824, chosen for its strategic location between Pensacola and St. Augustine, the two major Spanish settlements in the region at the time.

Montpelier is the capital of Vermont and is the smallest state capital in the United States by population, with fewer than 8,000 residents. It was chosen as capital in 1805 for its central location.

Shanghai is located on the Yangtze River delta, and the Yangtze River is the major river passing through the city. The Yangtze is the longest river in Asia and plays a crucial role in Shanghai's geography and economy as a major transportation route.

Moscow is built on the Moskva River, which flows through the center of the city. The Moskva River is a tributary of the Oka River and has been central to Moscow's development since the city's founding.

The Nile River flows through Cairo, Egypt, and is the lifeblood of the city and country. Cairo is located on the Nile River's banks, and the river has sustained Egyptian civilization for thousands of years.
