Addis Ababa is an important city in Africa. It serves as the capital of which country?

Introduction / Context:
Knowledge of world capitals is a fundamental part of general knowledge and political geography. Addis Ababa is not only a national capital but also a diplomatic hub in Africa, hosting many international organisations. This question asks you to identify which country has Addis Ababa as its capital, a fact that frequently appears in competitive examinations and map based questions.

Given Data / Assumptions:

• The city in question is Addis Ababa.
• We are to determine which country uses it as its capital.
• Options are Angola, Burundi, Chile, and Ethiopia.
• We assume current, widely accepted political boundaries and capital locations.

Concept / Approach:
Addis Ababa is the capital and largest city of Ethiopia, an East African country located in the Horn of Africa. It is also home to the headquarters of the African Union and other regional organisations, giving it continental importance. Angola's capital is Luanda, Burundi's capital is Gitega (previously Bujumbura was the main commercial centre), and Chile's capital is Santiago in South America. None of these match Addis Ababa. Therefore, Ethiopia is the correct choice.

Step-by-Step Solution:
Step 1: Recognise Addis Ababa as a well known African city often mentioned in news about African Union meetings. Step 2: Recall that Ethiopia is a landlocked country in the Horn of Africa and that Addis Ababa is its capital city. Step 3: Compare with Angola, whose capital is Luanda on the Atlantic coast. Step 4: Compare with Burundi, whose capital is Gitega (with Bujumbura as a commercial centre), not Addis Ababa. Step 5: Note that Chile is in South America, far from Africa, and has Santiago as its capital, confirming Ethiopia as the correct answer.

Verification / Alternative check:
Any standard atlas or world map listing countries and capitals shows Addis Ababa as the capital of Ethiopia. News reports covering African politics and summits often mention Addis Ababa in the context of Ethiopian government decisions and African Union conferences. Official websites of international organisations based in Africa also list their headquarters in Addis Ababa, Ethiopia. This broad consistency confirms that Ethiopia is the country whose capital is Addis Ababa.

Why Other Options Are Wrong:
Angola is an African country on the Atlantic coast, but its capital is Luanda, not Addis Ababa, so option A is incorrect. Burundi is a small African country in the Great Lakes region; its capital is Gitega and its largest city and former capital is Bujumbura, so option B is wrong. Chile is not in Africa at all; it is a long, narrow country in South America with Santiago as its capital, making option C incorrect. Only Ethiopia has Addis Ababa as its capital city.

Common Pitfalls:
Students sometimes confuse African capitals due to the large number of countries and similar sounding names. Another pitfall is overlooking that Chile is on a different continent and should not be considered for an African capital. To avoid errors, consistently revise country capital pairs, especially for Africa and South America, and create mental maps associating Addis Ababa firmly with Ethiopia and with the African Union headquarters.

Final Answer:
Addis Ababa is the capital city of Ethiopia.
