Explanation: The capital of Singapore is Singapore itself. This is a unique situation because Singapore is a city-state, which means it is a sovereign state that consists of a single city. The concept of a city-state is important in understanding the political geography of certain countries. In a city-state, the city and the state are one and the same, and the city serves as the center of government, administration, and often the economy of the state.
Singapore, located in Southeast Asia, is an example of a modern city-state. It gained independence from Malaysia in 1965 and has since developed into a major global financial center and a hub for international trade. The city-state is known for its efficient governance, high standard of living, and advanced infrastructure.
The confusion in the options provided can be attributed to several factors:
1. **Sentosa**: Sentosa is a popular resort island located off the southern coast of Singapore. It is known for its beaches, theme parks, and other tourist attractions. However, it is not the capital of Singapore; it is a part of the city-state but not the political center.
2. **Sydney**: Sydney is the capital city of New South Wales, a state in Australia. It is a major city in its own right but is not related to Singapore in terms of geography or governance.
3. **Ottawa**: Ottawa is the capital city of Canada, located in North America. It is unrelated to Singapore and is chosen here to test the student's knowledge of global capital cities.
Understanding the concept of a city-state is crucial for correctly identifying the capital of Singapore. A city-state is a type of sovereign state that consists of a single city and its dependent territories. Other examples of city-states include Vatican City and Monaco. In these cases, the city and the state are inseparable, and the city serves as the capital by default.
In summary, the capital of Singapore is Singapore because it is a city-state, and the city itself is the center of government and administration for the entire country. This unique political structure is an important aspect of Singapore's identity and governance.
