The Philippines is an island nation in Southeast Asia made up of thousands of islands. What is the capital city of the Philippines?

Introduction / Context:
This question focuses on the capital city of the Philippines, an archipelagic country in Southeast Asia. Capital city questions are fundamental in world geography and often appear in competitive exams. The Philippines is known for its many islands, diverse culture, and large population. Its capital city, Manila, plays a central role in government, commerce, and history, so recognizing this city country pairing is important for general knowledge.

Given Data / Assumptions:

The country mentioned is the Philippines in Southeast Asia.
You are asked to select the capital city from four given options.
The options are Warsaw, Manila, Lisbon, and Doha, all of which are real capital cities of different countries.
Only one option corresponds to the Philippines, while the others belong to European or Middle Eastern states.

Concept / Approach:
The concept is straightforward country capital matching. The Philippines has Manila as its capital city, located on the island of Luzon. Manila forms part of a larger metropolitan region called Metro Manila, which is the political, economic, and cultural hub of the country. Warsaw is the capital of Poland in Europe, Lisbon is the capital of Portugal, and Doha is the capital of Qatar in the Middle East. None of these cities are in Southeast Asia, so they cannot be capitals of the Philippines. Correctly identifying Manila as the capital demonstrates accurate geographic knowledge.

Step-by-Step Solution:
Step 1: Note that the question is asking for the capital city of the Philippines.Step 2: Recall that Manila is the capital of the Philippines and is located on Luzon island.Step 3: Review the options and see that Warsaw is linked with Poland, Lisbon with Portugal, and Doha with Qatar.Step 4: Recognize that none of those three cities are in the Philippines or even in Southeast Asia.Step 5: Choose Manila as the correct answer because it is the only city that corresponds to the Philippines.

Verification / Alternative check:
Verification can be done using maps of Asia or world atlases. The Philippines appears as a group of islands with Manila marked on the western side of Luzon as the capital. Wikipedia, encyclopedias, and official government websites all list Manila as the capital city of the Philippines. They frequently reference Metro Manila as the main urban region that includes the capital. In contrast, Warsaw, Lisbon, and Doha are always linked with Poland, Portugal, and Qatar respectively, never with the Philippines. This consistent information confirms that Manila is correct.

Why Other Options Are Wrong:
Warsaw is the capital of Poland in central Europe and has no role in Philippine governance. Lisbon is the capital of Portugal, a country on the Iberian Peninsula in southwestern Europe. Doha is the capital city of Qatar, a small but wealthy state on the Arabian Peninsula in the Middle East. Since the question is specifically about the Philippines, all these cities are incorrect. Only Manila is the true capital of the Philippines.

Common Pitfalls:
A common error is to answer based on vague familiarity with capital names without matching them to the correct region. All the distractor cities are well known, so test takers may choose them at random if they have not studied systematically. To avoid this, learners should organize capitals by region and practice recalling them along with the countries and continents they belong to. For the Philippines, remembering Manila together with Southeast Asian neighbors such as Bangkok for Thailand and Jakarta for Indonesia can help reinforce the association in memory.

Final Answer:
The capital city of the Philippines is Manila.
