In world geography general knowledge, what is the capital city of Ethiopia, the landlocked country located in the Horn of Africa on the eastern side of the African continent?

Introduction / Context:
This general knowledge question tests your awareness of world capitals, with a specific focus on the African nation of Ethiopia. Knowing the capital cities of different countries is a common part of competitive exams and quiz competitions because it reflects basic geographical literacy. Ethiopia is one of the oldest civilizations in the world and plays an important role in African politics and culture, so its capital city is frequently asked in exams.

Given Data / Assumptions:

The country in question is Ethiopia.
The question asks specifically for the capital city of Ethiopia.
The options provided are Addis Ababa, Santo Domingo, Port-au-Prince, and New Delhi.
Each option is the capital of some other well known country except the correct one for Ethiopia.

Concept / Approach:
The core concept here is simple recall of country capital pairs. Ethiopia is a landlocked country in the Horn of Africa. Its political and administrative capital is Addis Ababa. Addis Ababa is also an important diplomatic hub that hosts the headquarters of the African Union and several international organizations. The other options are all real capital cities, but they belong to different countries and serve as distractors. To answer correctly, you must match Ethiopia with Addis Ababa rather than confusing it with other capitals from the Caribbean or Asia.

Step-by-Step Solution:
Step 1: Read the question carefully and identify the country name, which is Ethiopia.Step 2: Recall or review the list of African capitals and confirm that the capital of Ethiopia is Addis Ababa.Step 3: Examine the options one by one and mentally match each to its known country.Step 4: Recognize that Santo Domingo is the capital of the Dominican Republic, Port-au-Prince is the capital of Haiti, and New Delhi is the capital of India.Step 5: Conclude that Addis Ababa is the only option that correctly matches Ethiopia, so it is the correct answer.

Verification / Alternative check:
To verify your answer, you can consult an atlas, a geography textbook, or an official government or tourism website. All standard references list Addis Ababa as the capital and largest city of Ethiopia. It is the center of government, major institutions, and foreign embassies. Addis Ababa also hosts the African Union headquarters, which reinforces its status as a major political city in Africa. None of the other options have any administrative connection with Ethiopia, confirming that they are only distractors in this question.

Why Other Options Are Wrong:
Santo Domingo is the capital of the Dominican Republic in the Caribbean, not of Ethiopia. Port-au-Prince is the capital of Haiti, another Caribbean nation that is completely separate from Ethiopia geographically and historically. New Delhi is the capital of India in South Asia, which is far from the Horn of Africa. None of these cities serve as the capital of Ethiopia, so they are incorrect options for this particular question.

Common Pitfalls:
A common mistake in capital city questions is to rely only on vague recognition of names. Many learners recognize New Delhi or other famous cities and select them simply because they look familiar, even when they do not match the country in the question. Another pitfall is confusing African capitals with each other, especially if you study them in a hurry. A good way to avoid this is to associate each country with a brief mental image or keyword, such as Addis Ababa with the African Union and Ethiopian history. Regular revision of world capitals using maps and flashcards helps fix these associations in long term memory.

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