Which of the following cities is both a harbour and a capital?

Analyze the question: We need a city that is a capital city (the seat of government of its country) and also a harbour (a port on the coast).

Check each option:

• A. Accra: This is the capital of Ghana and it is on the coast. However, Ghana's main harbours are Tema and Takoradi. Accra itself is not considered a true harbour city.
• B. Abidjan: This is a major port on the Atlantic coast and the economic capital of Côte d'Ivoire. The official capital is Yamoussoukro, so Abidjan is not the capital.
• C. Banjul: This is the capital of The Gambia. It sits on St Mary's Island at the mouth of the River Gambia, and it is the country's main seaport. It is both a capital and a harbour.
• D. Abuja: This is the capital of Nigeria but it is inland, so it has no harbour.

Answer: Banjul is the only option that is both a capital and a harbour.

Tip: Watch for "capital" traps. Abidjan is the famous port but not the official capital, and Abuja is the capital but landlocked. Remember the Gambian capital as "Banjul, the port on the river mouth." For this kind of question, test each city twice: Is it the capital? Is it a port?
